NEET BIOLOGY

Detailed explanation-1: -Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar. Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts.

Detailed explanation-2: -Plants are autotrophs, which means they produce their own food. 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-3: -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.

Detailed explanation-4: -Photosynthesis happens in small compartments within the plant cells, called chloroplasts. In a two-step process, plants obtain chemical energy from sunlight. The collected energy is used in a second reaction to produce the sugar glucose.

Detailed explanation-5: -(i) Photosynthesis is a process used by plants and other green organisms to convert light energy into chemical energy. (ii) Photosynthesis takes place only in the presence of sunlight. (iii) Only glucose is formed in the process of photosynthesis.
