Biology- Photosynthesis Coursework
The task set was to -
"Investigate the relationship between light intensity and the rate of Photosynthesis"
Photosynthesis
"Photosynthesis is a scientific process by which green plants trap light energy from the Sun. This energy is used in the making of chemical reactions, which lead to the formation of carbohydrates. The carbohydrates are found in the form of simple sugar, or glucose, which provides the basic food for both plants and animals. For photosynthesis to happen, the plant must possess chlorophyll and must have a supply of carbon dioxide and water. Photosynthesis takes place inside chloroplasts, which are found mainly in the leaf cells of plants.
The by-product of photosynthesis, oxygen, is of great importance to all living organisms, and virtually all-atmospheric oxygen has originated by photosynthesis.
Chloroplasts contain the enzymes and chlorophyll necessary for photosynthesis, and the leaf structure of plants is specially adapted to this purpose.
Most of the glucose that forms during photosynthesis is stored in the chloroplasts as starch. As plant- eating animals eat the leaves they too depend on plant photosynthesis to supply their basic energy needs. Photosynthesis depends on the ability of chlorophyll to capture the energy of sunlight and to use it to split water molecules.
