NEET BIOLOGY

Detailed explanation-1: -Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases. This function is performed by stomata. Water is absorbed by roots from the soil, whether from irrigation or rain.

Detailed explanation-2: -The conversion of sunlight into usable chemical substances is attained by chlorophyll. The raw materials needed for the process of photosynthesis are CO2 and H2O. 6 molecules of water and 6 molecules of carbon dioxide with the help of sunlight produce glucose and 6 molecules of oxygen.

Detailed explanation-3: -Sunlight, chlorophyll, carbon dioxide, water and minerals are raw materials essential for photosynthesis.

Detailed explanation-4: -During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
