Explanation

Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll. In this process, green plants and some bacteria change light energy and carbon dioxide gas into usable chemical energy in the form of a sugar called glucose. Carbon dioxide plus water yields glucose and oxygen gas.
