NEET BIOLOGY

Detailed explanation-1: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Detailed explanation-2: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-3: -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-4: -There are four factors which are necessary for the process of photosynthesis, water, carbon dioxide, sunlight, and chlorophyll. Chlorophyll pigments are present in the plant, carbon dioxide is obtained from the atmosphere, water is absorbed from the soil by the roots.

Detailed explanation-5: -The process of photosynthesis is completed in the following three steps: Absorption of sunlight : Pigment chlorophyll absorbs the Sunlight. Splitting of Water. Conversion of light energy into chemical energy, and splitting of water into hydrogen and oxygen by light energy.
