During photosynthesis which gas is absorbed by plants?

Options

A. Oxygen
B. Nitrogen
C. Carbon dioxide
D. Phosphorus

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose. It primarily occurs in the presence of sunlight, water (H2O), and carbon dioxide (CO2).

2. **Identifying the Reactants**: In photosynthesis, the main reactants are carbon dioxide (CO2) and water (H2O). The plants absorb these substances to produce glucose (C6H12O6) and oxygen (O2).

3. **Role of Chlorophyll**: The green pigment in plants, known as chlorophyll, plays a crucial role in capturing sunlight, which is necessary for the photosynthesis process.

4. **Gas Absorption**: The question specifically asks which gas is absorbed by plants during photosynthesis. It is important to differentiate between the gases absorbed and emitted by the plants.

5. **Conclusion**: During photosynthesis, plants absorb carbon dioxide (CO2) from the atmosphere. This gas is essential for the production of glucose and oxygen.

6. **Final Answer**: The gas absorbed by plants during photosynthesis is carbon dioxide (CO2).
