Question

Explain why photosynthesis is considered the most important process in the biosphere?

Answer 1

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce glucose. In this process, cellular respiration converts into ATP, the fuel used by all living things.

Complete Answer:
- Photosynthesis is the process by which green plants and certain other organisms renovate light energy into chemical energy. During the process of photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
- Mainly there are two types of photosynthetic processes, oxygenic photosynthesis, and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very much related, but oxygenic photosynthesis is the most common and which are mainly seen in plants, algae, and cyanobacteria.
- Photosynthetic organisms, including plants, algae, and some bacteria, play a vital role. They establish chemical energy and fix carbon into the ecosystems by using light to synthesize the sugars. These organisms produce their own food i.e. fix their carbon using light energy. They are generally called photoautotrophs (meaning self-feeders that use light).
- Humans and other organisms that cannot convert carbon dioxide to organic compounds themselves are known as heterotrophs. Heterotrophs must get the carbon fixed by eating other organisms or by eating their by-products. Animals, fungi, and many prokaryotes and protists are included in the group of heterotrophs. Plants are the most common autotrophs in terrestrial land ecosystems.
- All the green plant tissues can photosynthesize. But in most plants, the majority of photosynthesis usually takes place in the leaves. The cells in a middle layer of leaf tissue are called the mesophyll and they are the primary position of photosynthesis. Both photosynthesis and cellular respiration involve a series of redox reactions. In cellular respiration, electrons flow from glucose to oxygen, forming water and releasing energy.

Note: Photosynthesis takes place in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. Photosynthesis is the process that is used by plants, algae, and certain bacteria to bind energy from sunlight and turn it into chemical energy.
