Investigation on how light intensity affects the rate of Photosynthesis.

Introduction: Photosynthesis is the process by which green plants use the sapless muscularity to convert carbon dioxide and irrigate into simple sugar called glucose, which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain transfigure cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll, consisting by and large of carbon and hydrogen. It gives green color and absorbs the necessary lightsome for photosynthesis. Chloroplasts nuclear number 18 found in palisade cells, they drive home a huge surface area, which means there is more change of light hitting a chloroplast. Light is a very cardinal factor when it comes to the process of photosynthesis, with forth light the reaction cannot be carried out and no glucose can be made. Light saturation is maven of the factors that affect the run of photosynthesis and that is what our essay is based on: Aim: In this experiment we shal l check out how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light intensity in pissing plants. Hypothesis: I predict that as the intensity of light increases, so go out the rate of photosynthesis. Furthermore, I hypothesise that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate.

Variables: everlasting VariedMeasured ShootLight intensityRate of photosynthesis Number of lightsDistance between light and pondweedNumber of Bubbles Water ------ Time between each result record ------ Materials: - Beaker almost fu ll of water - Pondweed - 60 watt Lamp - Rule! r - Stopwatch - Short-stemmed funnel - Test Tube -paper clip -pure CO2 Method: 1. source clip that end of the pondweed that was not cut. 2. Then commit a short-stemmed funnel over some pondweed in a beaker of water. Add pure CO2 to the beaker of water. 3. Fill a test tube with water... The decrease is caused by the light chroma point.. though I am not very grade of what it means.. If you want to get a full essay, order it on our website: OrderCustomPaper.com
