What is the significance of photosynthesis?

Question

Write a short note on the significance of photosynthesis.

Answer 1

Significance of Photosynthesis:

1. Green plants possess the green pigment, chlorophyll which can capture, transform, translocate and store energy which is readily available for all forms of life on this planet. 
2. Photosynthesis is a process in which light energy is converted into chemical energy. 
3. Except green plants no other organism can directly utilise solar energy, hence they are dependent on green pants for their survival. 
4. Green plants can prepare organic food from simple inorganic elements (autotrophic) while all other organisms cannot prepare their own food and are called heterotrophic. 
5. During photosynthesis, oxygen liberated into the atmosphere makes the environment livable for all other organisms. 
6. Simple carbohydrates produced in photosynthesis are transformed into lipids, proteins, nucleic acids and other organic molecules. 
7. Plants and plant products are the major food sources of almost all other organisms of the earth. 
8. Fossil fuels like coal, gas, oil etc represent the photosynthetic products of the plants belonging to early geological periods.
