In the experiment‚ the effect of light intensity on the rate of photosynthesis will be tested. Photosynthesis is the process in which autotrophic plants create their own food (energy) from sunlight. Photosynthesis involves three ‘ingredients’ or reactants‚ carbon dioxide‚ water‚ and light energy (sunlight). Carbon dioxide and sunlight come in through a leaf’s stomata which are tiny holes‚ and water is absorbed through their roots. When all of these reactants are combined in a plant’s chloroplasts

How does light intensity affect the rate of photosynthesis? Poorly Pondweed Questions 1) How does light intensity affect the rate of photosynthesis? 2) How does temperature affect the rate of photosynthesis? sunlight carbon dioxide + water glucose + oxygen chlorophyll sunlight 6CO2 + 6H2O àààààà C6H12O6 + 602 chlorophyll Prediction I predict that the more intense the light‚ the higher the rate of photosynthesis. To photosynthesise‚ plants need light. It provides the energy for the process

For this experiment I am investigating how the light intensity as my limiting factor will have in impact on the amount to oxygen produced‚ to should the rate of photosynthesis.Therefore‚ all the controlled variables must remain constant‚ if not there could be an affect on the accuracy of the dependent variable. The CO2 levels are the same for each trial because before placing the sodium hydrogen carbonate i will weigh it with a measuring scale for 1.5 grams. After completing the five measurements

This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of

How does light intensity and carbon dioxide levels affect photosynthesis rate Phaladi Phaladi 201102379 Department Of Mathematics And Science Education University Of Botswana 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. As with many chemical process energy is need to make and break molecules during the chemical process. The greater the light levels the more energy is available to carry
Premium Carbon dioxide Photosynthesis Oxygen
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. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll‚ consisting largely of carbon and hydrogen. It gives green color and absorbs the necessary light for photosynthesis. Chloroplasts

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. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from

changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined

out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because light intensity
