The aim of the experiment was to determine whether different light intensities have different effects on the rate of photosynthesis of two plants, one grown in normal light conditions and one grown in shade conditions. Then from the syringe I will fill it with water and then ensure that the syringe head is pushed entirely in. According to my results my prediction was correct. Phaladi Phaladi
At higher temperatures, the thin Then the other ruler parallel to the test tube. ...Aim
2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. The plant then uses the glucose to produce energy which the plant needs to sustain life. At the same time as this the left over water vapour and oxygen are diffused out also through the stomata which again have to be turgid to let it out. I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. This carbon dioxide will be supplied by sodium bicarbonate dissolved in … But I do feel I could have changed a few things about the experiment. Aim. Then I will measure at 11 different distances (three times each) of the light away from the test tube with the plant in and then pull the syringe head out. The effect of light intensity on the rate of photosynthesis StudyMode.com. glucose is the resulting energy that is needed by the plant to grow and survive. The rate of photosynthesis increases linearly with increasing CO2 concentration (from point A to B ). More light, more molecules 'energised' to react. The effect of light, temperature and carbon dioxide in the air can be measured experimentally, varying one factor while keeping the others the same. So a greater light intensity gives a greater rate of photosynthesis. I did not have any anomalous results. I don’t feel that I could improve the way I carried out the experiment. For example I could have examined other variables such as lack of air or no soil or changes in water amounts given to the process of photosynthesis etc. Prediction. Yes, another boring IAA exam which makes it vital to have no slip ups in the method, validity, reliability, evaluation or conclusion. This will then reveal, (after a pre-set time of 5 minutes timed by the stopwatch) how much oxygen was given off measured in cm by the ruler next to the tube. I was correct as when we look at the for example we notice at the distance of 50 cm that the measurement of Oxygen was 2.96 cm where at when we look at the distance of 100 cm we see that it has approximately halved to 1.1 cm. The reason In photosynthesis, a plant takes Thus, if light intensity increases, then more leaf chads float because of increased photosynthetic rate. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants. Prediction. ...In my investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis.
This is because light energy is a driving force in photosynthesis, and one of the products of photosynthesis (oxygen) causes the leaf chads to float. According to past comparative studies, the dry matter of roots, stems, leaves, and whole plant as well as the photosynthetic rate, transpiration, an… In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. I had no problems due to the use of the computer program and overall I felt the experiment went well. Oxygen is the waste product that is given out via the stomata pores when they become turgid, this is during the process of respiration. light intensity, a slight trend suggested light intensity did have an effect on the rate of photosynthesis. Experiment to show the effect of different wavelengths of light during the process of photosynthesis: 5.

These bubbles can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis. It is taken in by the green pigment in all plant cells called chlorophyll, which is located in the chloroplasts of the cell. This easy science project shows simple and efficient method of chlorophyll extraction from a plant. StudyMode - Premium and Free Essays, Term Papers & Book Notes. 00:25 What is the colour change of the indicator if photosynthesis is occurring (faster than respiration)? I found that the experiment was easy to do. The active compounds in herb drugs are mainly secondary metabolites, which are greatly influenced by external conditions. Web. Retrieved 03, 2004, from https://www.studymode.com/essays/Effect-Light-Intensity-Rate-Photosynthesis-64970458.html, "The effect of light intensity on the rate of photosynthesis" StudyMode.com. 61, 62, 63) AIM The aim of this experiment is to investigate the effects of light intensity on the rate of photosynthesis by counting oxygen bubbles. We are using 2 kinds of light … 2004. Although the closer the light source is, the more p... ...does light intensity and carbon dioxide levels affect photosynthesis rate
I will set up my experiment using the following equipment: 1) test tube filled with water and 0.50 of sodium bicarbonate, 2) a plant that lives in a water ecosystem, 3) syringe connected to a clear tube and then to the test tube (with the plant inside). Prediction ... To investigate the effects of light intensity on photosynthesis. This is partly due to the fact we did the test via a computer program as the real test would be time consuming and less accurate. I think that the further away the light source is the smaller the rate of photosynthesis is. Light intensity and photoperiod had effects on the growth, survival and photosynthetic efficiency of corals. The concentration of water, carbon dioxide, the temperature and the light intensity are the most common environmental factors to affect photosynthesis (Lincoln 2010). It is best described from the following equation, Water + carbon dioxide sunlight glucose + oxygen, 6H O +6CO C H O +6O (The balanced equation). ; 01:22 What colour is the indicator solution at the start? This means that as the light moves away then there is less light given to the reaction for photosynthesis to happen. 03 2004. Background: Photosynthesis is a process that plants undergo to produce glucose. The reason that light intensity does affect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant. This easy science project shows simple and efficient method of chlorophyll extraction from a plant. Water is essential for the process of photosynthesis and also to stop the plant from wilting, because plant cells take up water via osmosis which makes them tight or turgid and so the plant stays upright, but if there is no water in the cell then the cell becomes flaccid and loose causing the plant to wilt and die. Light intensity is one of the factors affecting the rate of photosynthesis. 4. The only changes I will be making is to the light intensity by moving it closer or nearer to the plant. And so from my graph I can see that as the light moves away from the plant in the test tube that the rate of photosynthesis decreases. Aim: To investigate the effects of light intensity on photosynthesis. Also instead of measuring the length of the oxygen bubble I could have taken measurements changing the light intensity by percentage (%) or power of the light. Because due to the program we could easily set the temperature for 30 degrees and also easily set the time and the sodium bicarbonate and so make sure that all the possible variables stay the same. why plants have leaves, roots or being green is all linked Aim: In this experiment we shall investigate how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light intensity in water plants. Our library contains thousands of carefully selected free research papers and essays. We see this from the graph because the line of best fit drawn in goes on a downward slope indicating the amount of waste product of photosynthesis (oxygen). Light energy is needed for photosynthesis, so as the light intensity increases, the rate of photosynthesis chemical reactions steadily increases in a linear manner - 1st part of the graph is 'light limiting'. carbon dioxide from the air and water... ...Introduction: Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose, which provides a basic energy source for the plant. Other factors are concentration of carbon dioxide, temperature and to a lesser degree, water. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. ...In my investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis. This is only a demonstration of working method which can be refined and used for a full scale science project. In this experiment, the light intensity is changed by changing the distance of the source of light closer or further away from the elodea, so theoretically, when the intensity becomes stronger due to the light source being closer to the Elodea, the rate of photosynthesis should increase and therefore the number of oxygen bubbles will increase too. Biology Coursework ¡V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. GROUP MEMBERS: MARITONI VALENCIA, SANGITA TAMANG, RYUTARO SEIKI AND MAO The effect of light intensity followed a Michealis-Menten curve where increases in light intensity corresponded to increases in oxygen production until a peak in oxygen production occurred at a light intensity of 6000 lux. The rate of photosynthesis is determined by the number of bubbles formed by the Elodea plants. To work out how light intensity can affect the rate of photosynthesis. 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. Essaybank.co.uk/free_coursework/1649.html. Accessed 03, 2004. https://www.studymode.com/essays/Effect-Light-Intensity-Rate-Photosynthesis-64970458.html. In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. For most crop plants, even a slight increase or decrease in light intensity leads to considerable changes in leaf morphology and structure (Wu et al., 2017). As the bulb emits light in all direction we use the area of a sphere with the radius being the distance from the pond weed. Background: Photosynthesis is a process that plants undergo to produce glucose. 03, 2004. That corresponds with my prediction. You will then develop a conceptual model that explains why. The effect of light intensity on the rate of photosynthesis Photosynthesis depends on the amount of light available. Carbon dioxide is nessacery for the reaction of photosynthesis to take place, it gets in to the plant as one of the gases in air which then diffuses through the stomata pores (which have to be turgid to let it in and so need water for osmosis). later experiments on the effect of light intensity on photosynthesis.
This is because light plays a major role in photosynthesis, it helps the leaf to give out oxygen and take in carbon dioxide from the atmosphere which is polluting our world. You will notice that they are not direct halves of each other this is because of how much oxygen the plant decides to give off will change. ; 01:30 What colour is the indicator solution after illumination? ; 01:14 Why must the balls be restored to room temperature before use? ...Biology Coursework ¡V Does The Light Intensity
In this experiment a 100 Watt bulb was used. * I will leave the lamp to cool for 30 second periods between the different distances of the lamp to be tested. Photosynthesis is the process by which a plant cell converts carbon dioxide (CO2) to food sugars via light energy. The autora- diographic studies reported in Table 1 were done with algae from a temperature of 57C, where algal standing crop is the highest (Brock and Brock 1966; Brock 1967a). 1. Graph 1. Photosynthesis is how plants get their food. ...Aim
Photosynthesis represented by the equation 6H2O + 6CO2 → C6H12O6 + 6O2 is one of the most crucial chemical reactions on earth as it produces O2 molecules– a gas vital to the survival of many organisms (Vidyasagar, 2018) This process takes place during the light dependent phase of photosynthesis and is indicated by the production of bubbles and can be used to analyse the rate of photosynthesis (Benckiser, 2016). There are many factors, which affect the rate of photosynthesis, including light intensity, temperature and carbon dioxide concentration.”, Taken from www. I will follow the following safety precautions to make sure the test goes well. Also light helps photosynthesis to produce food for the … The rate falls gradually, and at a certain CO2 concentration it stays constant (from point B to C). Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. The results did approximately what I expected them to do ; decrease as the light was moved away so reducing the light intensity approximately proportional to the distance of which the lamp was moved. The Investigation
And finally sunlight is needed for the process of photosynthesis to take place. The plant then uses the glucose to produce energy which the plant needs to sustain life. 201102379
Evaluation The number of bubbles given off in a minute is taken as the rate of photosynthesis and plotted against the calculated light intensity. The faster the bubble moves, the greater the rate of transpiration. 03 2004
, "The effect of light intensity on the rate of photosynthesis" StudyMode.com. So the aim of this scientific experiment is to investigate the effects of light intensity on the rate of photosynthesis. Affect the Rate of Photosynthesis
The fact that all plants need light in order to photosynthesise has been proven many times in experiments, and so it is possible to say that without light, the plant would die. Increasing the light intensity will … No matter the topic you're researching, chances are we have it covered. When the light intensity is … Light intensity and quality are among the most critical environmental factors for crop physiology and biochemistry (Yang et al., 2018a). This is obtained by firstly the sunlight shining down on a plant, which gives the energy for the reaction to take place. My test will be fair, as I will be using the same equipment throughout my experiment and I will be taking all of the measurements throughout the experiment. Light Intensity = Power/Area. The portion of the leaf exposed to light gives positive starch test, i.e., it becomes deep blue in iodine solution, whereas, the covered portion of the leaf gives negative starch test and does not become blue-black in iodine solution. (2004, 03). Light intensity limitation. Use Cabomba or Elodea, which are sold in aquarium shops. Hypothesis
...The Effects of Light Intensity on the Rate of Photosynthesis
The effect of light intensity on photosynthesis can be investigated in water plants. #41 Effect of Light intensity on the rate of Photosynthesis Plants need light energy to make the chemical energy needed to create carbohydrates. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. And so when there is less energy the plant has the reduced ability to make glucose or food for itself to survive and so will give off less waste products as we see from the graph. V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. For example if one measurement is taken the if the light is moved away after it approximately double the distance then I would expect the rate of photosynthesis to drop. Then I will attach a clear tube to the test tube using a bung and on the other end of the tube I will attach securely the syringe.

Why is this? Here a rise in CO2 levels has no effect as the other factors such as light intensity become limiting. LIGHT INTENSITY. Experiment … There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in this case a half).
Then I will place the plant inside the test tube with the pre-set amount of sodium bicarbonate. As that is where the syringe will suck in the oxygen as shown below in the diagram. I also back my theory up using the following quote, “Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. With out this then even if the plant had all the nessacery reactants the photosynthesis would not take place. Department Of Mathematics And Science Education
. StudyMode.com, 03 2004. I predicted that as the light moved away the rate of photosynthesis decreases proportionately to the distance the light is moved away. 2), we want to determine the intensity and distance from light affect the rate of photosynthesis in aquatic plant because the plant itself needs more water to grow. This is because to cause the reaction of the reactants during photosynthesis this needs energy, which in a plants case comes form the sun light taken in by the green pigment called chlorophyll. (Walpole, Merson-Davies and Leighton, 2011, pg. The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. There fore I only plan to change the sunlight intensity because I feel that this would be the best variable for me to change to find out how light intensity affects the rate of photosynthesis. Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant’s ability to grow. Hypothesis: I predict that as the intensity of light increases, so will the rate of photosynthesis. "The effect of light intensity on the rate of photosynthesis" StudyMode.com. Increase in light intensity increases the rate of photosynthesis and less of it decreases its rate. Your Task Design a series of experiments to determine how temperature and light intensity affect the rate of photosynthesis in spinach. Plants contain many pigments in different proportions. Thus, as the amount of sunlight, or in this case light from a bulb, falls on the plant, more energy is absorbed, so more energy is available for the chemical reactions, and so more photosynthesis takes place in a given time.
Plants, through the use of chlorophyll (green pigment in plants) that traps light can generate ‘food’ by combining carbon dioxide in the air and water. Experiment to demonstrate that carbon dioxide enters the leaf through the stomata: 7. Water is taken in via the root hairs which stick out in to the soil, these are located on the roots themselves, because of these root hairs this gives the plant a bigger surface area in which it can absorb more water. Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen. Now I will place the meter ruler next to the test tube as shown in the diagram below and place the lamp along side it so the distance of the light can be measured accurately. To work out how light intensity can affect the rate of photosynthesis. Light intensity refers to the strength or amount of light produced and is the measure of the wavel…

What is Photosynthesis? affect how quickly photosynthesis takes place within a plant. * I will make sure the tempareture is not put on to high. (Root hairs also collect minerals and nutrients for the plant through active uptake). Plant Growth Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant’s use, according to the Texas A&M University Agricultural Extension Service. More oxygen bubbles are produced when the light is closer to the beaker. This experiment proves the necessity of light for photosynthesis. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. this is the same with the stomata pores except when they are turgid the pore opens and when flaccid the pore is closed.
The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Also we want to know if the rate of water could affect the photosynthesis process. First I will make sure that the temperature is set at 30 degrees Celsius. Aim: To investigate the effects of light intensity on photosynthesis. Photosynthesis is the process that plants use to create energy for themselves. The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Particularly, light intensity has a great influence on the photosynthesis and accumulation of secondary metabolites. INTRODUCTION:
The effect is that the higher the light intensity the increase in the amount of bubbles produced, this bubble produced from the plant is oxygen. This article will have all you need to know about the Biology IAA coursework on the investigation into the effect of light intensity on the rate of photosynthesis. 03 2004. But the way I explained to set up the experiment is the same way it was set up on the computer program, making my method correct. This would happen because of the age of the plant or the ability to carry out photosynthesis may have decreased slightly making it impossible to get exact answers. Experiment to determine the amount of chlorophyll ‘a’, chlorophyll ‘b’ and total chlorophyll in a given plant tissue: 6. 2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. ...The Effects of Light Intensity on the Rate of Photosynthesis
