Question

Name the process by which plants make their own food.

Answer 1

Photosynthesis:

1. Photosynthesis is a physiological process, by which green plants synthesize carbohydrates, with the absorption of solar energy from the sunlight and CO₂ from the atmosphere, and water from the soil.
2. O₂ is the by-product of this process.
3. The presence of chlorophyll is a must for this process.
4. Chlorophyll and other photosynthetic pigments help in the absorption of sunlight.

Chemical equation $6C{O}_2+12H_{2}O\underset{chlorophyll}{\overset{sunlight}{\to }}\frac{C_6{H}_{12}{O}_6+6O_2}{carbohydrate}+\frac{6O_2}{oxygen}\uparrow +\frac{6H_{2}O}{water}$

1. With the help of photosynthesis, plants make their own food
