NEET BIOLOGY

Detailed explanation-1: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

Detailed explanation-2: -1) Splitting of water molecules into hydrogen and oxygen by sunlight. 2) Absorption of light energy by chlorophyll. 3) Reduction of carbon dioxide to carbohydrates.

Detailed explanation-3: -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-4: -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-5: -The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
