Plants undergo a reaction called photosynthesis to turn the energy from the into food. In this reaction, carbon dioxide and are converted to glucose and oxygen using light energy absorbed by the .
Many factors influence the rate of photosynthesis. Light intensity varies with the law, which states that the amount of light a plant receives decreases with its distance from the light source. This property means that light intensity is often the for photosynthesis, especially since light intensity is often correlated with temperature. A temperature decreases the rate of photosynthesis because it means that particles have less energy and so reactions happen more slowly. The amount of and chlorophyll available also influences the rate. Many of these factors can be controlled in to ensure that plants have the optimum conditions for photosynthesis and growth.
The glucose that photosynthesis produces can be used in a variety of ways in the plant. It can be stored directly as , or used to produce fats or oils which can also be stored for later use. Much of the glucose is used directly in , and some may also be used to produce various compounds such as cellulose for or for protein synthesis. This last process also requires nitrate ions absorbed by the .
