Process of Synthesis of Food in Green Plants
Green plants undergo the process of photosynthesis to synthesize food. This process involves the conversion of light energy, usually from the sun, into chemical energy stored in glucose molecules. Let's break down the process in detail:

1. Absorption of Light
- Chlorophyll, a pigment found in chloroplasts of plant cells, absorbs sunlight.
- The light energy is used to split water molecules into oxygen and hydrogen ions.

2. Carbon Dioxide Uptake
- Carbon dioxide is taken in from the atmosphere through small pores called stomata on the leaves.
- The carbon dioxide combines with the hydrogen ions to form glucose molecules.

3. Production of Glucose
- The glucose molecules produced during photosynthesis serve as the primary source of energy for the plant.
- Excess glucose is stored in the form of starch in different parts of the plant.

4. Oxygen Release
- Oxygen, a byproduct of photosynthesis, is released into the atmosphere through the stomata.
- This oxygen is essential for the survival of other living organisms, including animals and humans.

5. Overall Impact
- Photosynthesis is a crucial process as it is the primary source of food for plants and indirectly for all living organisms.
- It also plays a vital role in maintaining the balance of oxygen and carbon dioxide in the atmosphere.
By understanding the process of photosynthesis, we can appreciate the significance of green plants in sustaining life on Earth.
