Detailed explanation-1: -Photosynthesis is the process in which plants collect radiant energy (from the Sun) and transform it into chemical energy.

Detailed explanation-2: -Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

Detailed explanation-3: -Chlorophyll a is termed as universal photosynthetic pigment as it is found in all photosynthetic plants except bacteria. It is also called primary photosynthetic pigment because it performs primary reaction of photosynthesis which involves conversion of light chemical energy.
