Detailed explanation-1: -What is photosynthesis? Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

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). Photosynthesis powers almost all trophic chains and food webs on the Earth.

Detailed explanation-3: -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-4: -Photosynthesis is the most fundamentally important energy-converting process on Earth. It converts solar energy to chemical energy and provides all the food we eat, the fossil fuels we consume and the oxygen we breathe.
