Photosynthesis

Introduction
The process of photosynthesis is vital to humans and all other living organisms
on earth. Through photosynthesis plants use water, carbon dioxide, and light to
supply themselves with food and the rest of the world with oxygen. Although all
plants carry out photosynthesis, the process by which they do so varies
depending on the plant. The rate at which plants produce oxygen is also
dependent on the plant. Two classifications of plants that differ in the way
they carry out photosynthesis are C3 plants and C4 plants. C3 plants such as
soybeans and rice go through two stages of photosynthesis which are light
reactions and the Calvin cycle. While in the light, during the Calvin cycle, C3
plants often go through a process called photorespiration when the plant uses O2
for the Calvin cycle instead of CO2 and therefore does not produce food or ATP.
This occurs when the weather gets too hot and dry for the stomata to be open and
