Describe the purpose and process of photosynthesis

Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.

Photosynthesis is the process in which the a plant gets energy from the sun also photosynthesis can happen when water gets into the roots of the plant.

i think it is true since you can test the answer and can use observations to complete it.
