Photosynthesis is the process by which plants, some bacteria, and some algae use the energy from sunlight to produce glucose in which cellular respiration converts into ATP that is used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we must have to live.

 The overall reaction of photosynthesis is:

   6H2O + 6CO2 ----------> C6H12O6+ 6O2

 

On this site you will learn the two stages of photosynthesis, how it works, and what molecules are used in the process. The equation that that is above will be shown step by step to help you understand more about photosynthesis. So sit back, relax, and enjoy the site!

The plant absorbs carbon dioxide from the atmosphere, draws water up through its roots and uses light to photosynthesize sugars, which it uses as food. It excretes oxygen as a by-product of the process. Without water, photosynthesis cannot take place.
