Photosynthesis & Cellular Respiration

Photosynthesis is the process where green plants use sunlight, carbon dioxide, and water to make food and oxygen. This is very important because all life depends on it for the oxygen. Photosynthesis is the source of energy for nearly all life on earth. Many photosynthetic organisms have adaptations that concentrate or store carbon dioxide, and helps take out photorespiration.

Cellular respiration is the set of metabolic reactions and processes that take place in the vells of organisms to change into biochemical energy. Respiration is one way a cell can gain useful energy to fuel cellular reformations. The energy released in respiration is used to synthesize ATP to store this energy.
