Ethylene is a by product of

Options

A. Developing seeds
B. Ripening in some furits
C. Developing ovules
D. Germinating seeds

Answer

**Step-by-Step Solution:**

1. **Understanding Ethylene**: Ethylene is a simple gaseous plant growth regulator (PGR) that plays a crucial role in various plant processes.

2. **Synthesis of Ethylene**: Ethylene is synthesized in large amounts by tissues undergoing senescence (aging) and by ripening fruits. This means that as fruits ripen, they produce more ethylene.

3. **Analyzing the Options**:
- **Option 1: Developing Seed**: This is incorrect because ethylene does not primarily function in the development of seeds; rather, it aids in the growth of seedlings.
- **Option 2: Ripening in Some Fruits**: This is correct. Ethylene is well-known for its role in the ripening process of fruits, making them softer and sweeter.
- **Option 3: Developing Ovules**: This is incorrect as ethylene does not play a significant role in the development of ovules.
- **Option 4: Germinating Seeds**: This is also incorrect because while ethylene can influence seed germination, it is not a by-product of the germination process itself.

4. **Conclusion**: The correct answer is that ethylene is a by-product of ripening in some fruits.

**Final Answer**: Ethylene is a by-product of ripening in some fruits.
