How do you describe the process of photosynthesis?

Explanation

Solution

Plants require nutrients for the same reason as animals need them. They need to germinate, grow, combat diseases and pests, and reproduce. Plants provide food to virtually all terrestrial species including humans. We consume vegetables or other species that eat plants.

Complete answer:
Photosynthesis is a mechanism by which autotrophs convert light energy into chemical energy that is subsequently used to power cellular activities. Chemical energy is contained in the form of sugars derived by water and carbon dioxide. Chloroplasts are photosynthetic sites of plants and blue-green algae. At the cellular level, the process of photosynthesis takes place in cell organelles called chloroplasts. These organelles contain a green pigment called chlorophyll, which is responsible for the characteristic green colouring of the leaves. During the photosynthesis process, carbon dioxide enters through the stomata, The water is absorbed from the soil by the root hairs. After which the water is carried through the xylem vessels to the leaves. The light energy from the sun absorbs chlorophyll to split water molecules into hydrogen and oxygen. In glucose production, hydrogen from water molecules and carbon dioxide consumed from the environment is used. In addition, as a waste product, oxygen is released into the atmosphere from the leaves. Glucose is a food supply for plants to provide energy for growth and production, while the remaining is retained in roots, leaves and fruits for later use.

Note: Photosynthesis reaction involves two reagents, carbon dioxide and water. These two reagents produce two products, namely oxygen and glucose. The photosynthesis reaction is therefore considered to be an endothermic reaction.
