HORTICULTURE

Detailed explanation-1: -In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1).

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.

Detailed explanation-3: -Plants use water, carbon dioxide, and sunlight to make sugar and oxygen. During photosynthesis radiant energy or solar energy or light energy is transferred into chemical energy in the form of sugar (glucose).

Detailed explanation-4: -During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
