What is photosynthesis?
Definition :
The process by which green plants and certain other organisms transform light energy into chemical energy.
How this process takes place ?
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
stages of photosynthesis :
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast:
(1) absorption of light,
(2) electron transport leading to the reduction of NADP+ to NADPH,
(3) generation of ATP, and
(4) conversion of CO2 into carbohydrates (carbon fixation).
