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 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. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-3: -Green plants manufacture glucose through a process that requires light, known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence of chemical reactions within the chloroplasts.

Detailed explanation-4: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-5: -Glucose can be used as a chemical building block and as an energy supplier. Plants use glucose to live and grow. For both plants and humans, glucose is like the fuel for a machine. Plants produce sugar in their leaves, but these leaves do not taste sweet.
