Importance of Photosynthesis

Learn about the process of photosynthesis and understand its importance to our green environment.

Importance of Photosynthesis

Photosynthesis is a crucial energy-converting process by which plants produce molecular oxygen and carbohydrates by the use of photons present in the light. The natural source of light, the sun, helps the green colored plants to fix the atmospheric carbon dioxide in to usable molecular oxygen, that we humans happen to breathe.


They help in maintaining a balanced level of oxygen and carbon dioxide in the atmosphere. Almost all the oxygen present in the atmosphere can be attributed to the process of photosynthesis, which also means that respiration and photosynthesis go together. Also, the chemical energy stored in plants is transferred to animal and humans when they consume plant matter. Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.


In a nutshell, the process of photosynthesis benefits us in the following ways:
  • 1. Photosynthesis converts inorganic raw materials into food, that provides our ecosystem with energy.
  • 2. Green plants provide organic food to all the animals and humans.
  • 3. Rare fossil fuels like coal, petroleum and natural gas are formed through the degradation of the past plant and animal parts, which were originally formed by photosynthesis.
  • 4. Plant products like timber, rubber, herbs, medicines resin and oils are derived from photosynthesis.
  • 5. Photosynthesis helps in providing oxygen in the atmosphere required by all living organisms.
  • 6. Photosynthesis decreases the concentration of carbon dioxide and other harmful industrial wastes that lead to respiration problems in living beings.
