DENDROLOGY

Detailed explanation-1: -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-2: -The glucose produced in photosynthesis may be: Used for respiration (both aerobic and anaerobic) Converted into insoluble starch for storage in the stems, leaves and roots. Used to produce fat or oil for storage (especially in seeds)
