Detailed explanation-1: -Only certain organisms, called autotrophs, can perform photosynthesis; they require the presence of chlorophyll, a specialized pigment that can absorb light and convert light energy into chemical energy.
Detailed explanation-2: -The correct option is A True. Photosynthesis: Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll, where oxygen is evolved as a by-product. It takes place in the leaves of the plant.
Detailed explanation-3: -It helps in trapping the sun light energy for the plant. It is a pigment necessary for the process of photosynthesis. Animals lack chlorophyll which is why they can not perform photosynthesis.
