Detailed explanation-1: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them. They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis.

Detailed explanation-3: -Leaves have mesophyll cells that contain chloroplasts in them. The chloroplast is a double-membraned organelle that contains the green-coloured pigment called chlorophyll which absorbs light from the sun and performs photosynthesis.

Detailed explanation-4: -The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
