Question

Photosynthesis is important because it ____.

• A. Synthesis food
• B. Purifies atmosphere
• C. Maintains a balance of gases in the atmosphere
• D. All of these

Answer 1

The correct option is D

All of these

The correct option is (D):
Explanation of the correct option:

1. Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll.
2. 6 CO₂ + 12 H₂O → Glucose (C₆H₁₂O₆) + 6 H₂O + 6 O₂
3. In this process, food is produced in the form of glucose for plants.
4. Oxygen evolved from the process is essential for survival and helps in purifying the environment.
5. Plants inhale carbon dioxide exhaled by animals and other sources in the process and oxygen released is crucial for animals.
6. Therefore, it helps in maintaining balance of gases in the atmosphere.

Final answer: Photosynthesis is important because it synthesizes food, purifies the atmosphere and maintains a balance of gases in the atmosphere.
