Plants is the only organism that undergo photosynthesis, photosynthesis is important because it produces oxygen that we breathe and Lessens carbon dioxide that we exhale.
Plants pull carbon dioxide from the atmosphere, releasing the  oxygen and retaining the carbon, in a process known as  photosynthesis. Most photosynthesis is performed by ma â¦ rine (ocean)  cyanobacteria.    Plants, trees and forests act as big carbon sinks, provided they do  not burn.lants pull carbon dioxide from the atmosphere, releasing the  oxygen and retaining the carbon, in a process known as  photosynthesis.
