Ethylene is

Options

A. Neither a growth promoter nor growth inhibitor
B. A nitrogenous phytohormone
C. A gaseous phytohormone that hastens fruits ripening
D. A volatile phytohormone that caused wounds in plants body

Answer

**Step-by-Step Solution:**

1. **Understanding Ethylene**: Ethylene is a plant hormone, also known as a phytohormone. It plays a significant role in various plant processes.

2. **Identifying the Nature of Ethylene**: Ethylene is classified as a gaseous compound. This is important because it distinguishes it from other types of phytohormones that may be solid or liquid.

3. **Evaluating the Options**:
- **Option 1**: "Neither a growth promoter nor a growth inhibitor" - This is incorrect. Ethylene can promote certain growth processes while inhibiting others, particularly in roots.
- **Option 2**: "A nitrogenous phytohormone" - This is also incorrect as ethylene is not nitrogenous; it is a gaseous compound.
- **Option 3**: "A gaseous phytohormone that has significance in fruit ripening" - This is correct. Ethylene is well-known for its role in the ripening of fruits.
- **Option 4**: "A volatile phytohormone that caused wounds in the plant body" - This is misleading. While ethylene is volatile, it does not cause wounds; that role is attributed to auxins.

4. **Conclusion**: The only correct statement regarding ethylene is that it is a gaseous phytohormone that plays a significant role in fruit ripening.

**Final Answer**: Ethylene is a gaseous phytohormone that has significance in fruit ripening.
