EVERYDAY SCIENCE

Detailed explanation-1: -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: -nectar, sweet viscous secretion from the nectaries, or glands, in plant blossoms, stems, and leaves. Nectar is mainly a watery solution of the sugars fructose, glucose, and sucrose but also contains traces of proteins, salts, acids, and essential oils.

Detailed explanation-3: -In contrast to humans and other animals, plants can produce glucose through a process known as photosynthesis. The green parts of plants use sunlight, water, and the gas carbon dioxide from the air to produce glucose and oxygen.
