effect of light intensity on photosynthesis experiment

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. Photosynthesis is how plants get their food. Explanation. 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. Background: Photosynthesis is a process that plants undergo to produce glucose. Biology Coursework! Light intensity and photoperiod had effects on the growth, survival and photosynthetic efficiency of corals. #41 Effect of Light intensity on the rate of Photosynthesis Plants need light energy to make the chemical energy needed to create carbohydrates. Thus, if light intensity increases, then more leaf chads float because of increased photosynthetic rate. 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). The effect of light intensity on photosynthesis can be investigated in water plants. 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. The concentration of water, carbon dioxide, the temperature and the light intensity are the most common environmental factors to affect photosynthesis (Lincoln 2010). 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. 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. Hypothesis: I predict that as the intensity of light increases, so will the rate of photosynthesis. 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. Then the other ruler parallel to the test tube. Light intensity is one of the factors affecting the rate of photosynthesis. why plants have leaves, roots or being green is all linked Then I will place the plant inside the test tube with the pre-set amount of sodium bicarbonate. When the light intensity is … According to past comparative studies, the dry matter of roots, stems, leaves, and whole plant as well as the photosynthetic rate, transpiration, an… Prediction. The effect of light, temperature and carbon dioxide in the air can be measured experimentally, varying one factor while keeping the others the same. In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. I will follow the following safety precautions to make sure the test goes well. This easy science project shows simple and efficient method of chlorophyll extraction from a plant. 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). 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. 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. 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. Here a rise in CO2 levels has no effect as the other factors such as light intensity become limiting. This experiment proves the necessity of light for photosynthesis. Plants contain many pigments in different proportions. More oxygen bubbles are produced when the light is closer to the beaker. The chemical equation for photosynthesis can be expressed as: (light) 6CO2 + 6H2O ( C6H12O6 + 6O2 (in the presence of chlorophyll). It is taken in by the green pigment in all plant cells called chlorophyll, which is located in the chloroplasts of the cell. I predicted that as the light moved away the rate of photosynthesis decreases proportionately to the distance the light is moved away. 03 2004 , "The effect of light intensity on the rate of photosynthesis" StudyMode.com. The rate falls gradually, and at a certain CO2 concentration it stays constant (from point B to C). Oxygen is the waste product that is given out via the stomata pores when they become turgid, this is during the process of respiration. Also light helps photosynthesis to produce food for the … Aim. I think that the further away the light source is the smaller the rate of photosynthesis is. The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Discover great essay examples and research papers for your assignments. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Particularly, light intensity has a great influence on the photosynthesis and accumulation of secondary metabolites. 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. 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. Department Of Mathematics And Science Education The number of bubbles given off in a minute is taken as the rate of photosynthesis and plotted against the calculated light intensity. The active compounds in herb drugs are mainly secondary metabolites, which are greatly influenced by external conditions. 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. The Investigation 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. ...The Effects of Light Intensity on the Rate of Photosynthesis StudyMode.com, 03 2004. Prediction. 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. . According to my results my prediction was correct. At higher temperatures, the thin 03 2004. 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). Our library contains thousands of carefully selected free research papers and essays. 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. You will then develop a conceptual model that explains why. I don’t feel that I could improve the way I carried out the experiment. Then from the syringe I will fill it with water and then ensure that the syringe head is pushed entirely in. 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). glucose is the resulting energy that is needed by the plant to grow and survive. Yes, another boring IAA exam which makes it vital to have no slip ups in the method, validity, reliability, evaluation or conclusion. ...Aim 2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. 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. These bubbles can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis. Increase in light intensity increases the rate of photosynthesis and less of it decreases its rate. Experiment … More light, more molecules 'energised' to react. I did not have any anomalous results. 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. Is closed, more molecules 'energised ' to react as that is needed for the light intensity affect.
