INVESTIGATION INTO THE FACTORS AFFECTING THE RATE OF PHOTOSYNTHESIS

AIM- To identify the factors affecting the rate of photosynthesis and, choosing one factor, to ascertain the effects it has.

Photosynthesis is an endothermic reaction that occurs in plants, by which plants use light energy to make glucose. It needs energy from the photons of light and it is their anabolic effect on the plant that gives the energy for the reaction to take place. During this process carbon dioxide combines with water to from glucose, and oxygen is released. The glucose made then has many uses in the plant: respiration, making ATP, active uptake….
Sunlight and chlorophyll must be present for the reaction to take place, and the light is trapped in the chlorophyll:

sunlight
Carbon dioxide + Water Glucose + Oxygen.
Chlorophyll


The amount of oxygen given off is an indication of the rate of photosynthesis. The more oxygen being given...
