Detailed explanation-1: -Plants synthesise their own food by the process of photosynthesis. Food is synthesised by the plants in the form of glucose, stored in the form of starch and is transported in the form of sucrose.

Detailed explanation-2: -Plants use a process called photosynthesis to make food. 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.

Detailed explanation-3: -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-4: -Glucose is usually present in solid form as a monohydrate with a closed pyran ring (dextrose hydrate). In aqueous solution, on the other hand, it is an open-chain to a small extent and is present predominantly as -or -pyranose, which interconvert.

Detailed explanation-5: -Plants synthesise glucose during the process of photosynthesis. The excess of glucose is stored in the form of starch. It is stored in roots, leaves, tubers, bulbs. Cellulose is present in the cell wall of the plants.
