Photosynthesis

Photosynthesis. Chapter 8. PHOTOSYNTHESIS. Life is powered by the sun. The vast diversity of life on the Earth is due to about 1% of that radiant energy. Photosynthesis comes in different forms, anoxygenic & oxygenic. In plants, photosynthesis takes place primarily in the leaves.

Photosynthesis- The Basis for Life on Earth

Photosynthesis- The Basis for Life on Earth. Photosynthesis- is the process that converts light energy into chemical energy. This chemical energy is usually a carbohydrate. Only photoautotrophs can do photosynthesis. Heterotrophs must obtain their high organic nutrients from the environment.
