What is the process of photosynthesis​
statuscvo [17]

The process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.

<h3>WHAT IS PHOTOSYNTHESIS?</h3>

Photosynthesis is the process whereby green plants obtain their food (glucose) in the presence of sunlight as an energy source.

Photosynthesis takes place in two stages namely;

  • Light dependent reactions
  • Light independent reactions

Photosynthesis combines carbon dioxide and water as reactants as follows:

6CO2 + 6H2O = C6H12O6 + 6O2

Therefore, the process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.
