Question

How does photosynthesis take place?

Answer 1

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar.
The overall chemical reaction involved in photosynthesis is:
$6C{O}_2+6H_{2}O(+lightenergy)\to C_6{H}_{12}{O}_6+6O_2.$
There are two parts to photosynthesis. They are called the light reaction and the dark reaction.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. Furthermore, two further compounds are generated: reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.
