Summary:In photosynthesis, green plants use the energy of sunlight to convert carbon dioxide into hydrocarbons that promote plant growth while generating oxygen from water and releasing the oxygen to the atmosphere. All animals including humans depend either directly or indirectly on this source of food and oxygen. Consequently, photosynthesis is considered the most important chemical process on Earth.

Photosynthesis
What is the chemical equation for photosynthesis?CO2 + 2H2O >> CH2O + O2 + H2O.
What organelles are involved in this process?chloroplasts
List three things you learned from this article in your own words.This helps the plant grow, all animals depend on this , and it is the most important chemical process on earth.
What impact would the absence of this process have on the biosphere?there wouldn't be any oxygen on earth.
