Answer: light intensity, chlorophyll density, water, carbon dioxide
Explanation:
Photosynthesis is a chemical process that occurs in the leaf cells of the plants. In this the light energy from sun is converted into chemical energy in the form of food. The light energy from sun is captured by the chlorophyll pigment of the leaf cells. The more the density of chlorophyll pigment the speed of the reaction will be more as it will be able to capture more amount of light energy.
The light intensity is also important because the more intense the light the more frequent will be the production of food products.
Water and carbon dioxide are the chief reactant for the process of photosynthesis. The more the concentration of the reactant the faster will be the rate of the reaction.
