Photosynthesis and Cell respiration

by julius jackson


  1. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Cell Respiration

    the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

The Differences Between the Two

In other words, photosynthesis needs energy to make glucose, while cellular respiration uses this glucose to actually create energy. In scientific equations, photosynthesis takes carbon dioxide from the air, water and sunlight to create sugar. After this happens, oxygen is released back into the air.
