AT1: Photosynthesis and Limiting Factors Aim: In this experiment, I will test to see how heat affects the rate of photosynthesis in a water plant as a limiting factor. Background Knowledge: Photosynthesis is the process by which chlorophyll containing organisms, (namely green plants, algae, and some bacteria), capture energy in the form of light and convert it to chemical energy. Virtually all the energy available for life in the earth's biosphere, (the zone in which life can exist), is made available through photosynthesis. A generalized chemical equation for photosynthesis is: Carbon Dioxide + Water + light energy = Sugar (Glucose) + Oxygen + Water This can be seen as two different chains of reactions... One involves the transfer of light energy into chemical energy that is light intensity dependant - if it is lighter the reaction happens more efficiently. The other shows the creation of glucose and is heat dependant. The glucose is created by carbon dioxide and...
