A gas required for germination of (Pea) seed is

Options

A. Nitrogen
B. Oxygen
C. Hydrogen
D. Water vapours

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Germination**: Seed germination is the process by which a seed develops into a new plant. This process involves various physiological changes, including rapid cell division.

2. **Energy Requirement**: During germination, seeds require energy to fuel the rapid cell division that occurs. This energy is primarily obtained through metabolic processes.

3. **Role of Oxygen**: One of the key metabolic processes involved in generating energy is oxidation. Oxidation requires oxygen, which is taken from the atmosphere.

4. **Evaluating Options**:
- **Nitrogen**: While nitrogen is essential for plant growth, it is not directly required for the germination process.
- **Oxygen**: This is the correct answer, as it is necessary for the oxidation process that provides energy for germination.
- **Hydrogen**: This gas is not required for seed germination.
- **Water Vapors**: Although water is essential for germination, it is not classified as a gas required for the process.

5. **Conclusion**: Based on the analysis, the gas required for the germination of pea seeds is oxygen.

**Final Answer**: The gas required for germination of pea seeds is **Oxygen**.
