Male hormone in plant is

Options

A. auxin (IAA)
B. gibberellin (GA)
C. cytokinin (CK)
D. ethylene

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks for the male hormone in plants. We need to identify which plant hormone is considered the male hormone.

2. **Reviewing the Options:**
- **Auxin:** This hormone is primarily involved in cell elongation and growth, but it is not specifically a male hormone.
- **Gibberellin:** This hormone is known for promoting growth, particularly in stems and seeds. It plays a role in the development of male flowers and is often compared to testosterone in animals.
- **Cytokinin:** This hormone is involved in cell division and growth, but it does not specifically relate to male characteristics.
- **Ethylene:** This hormone is primarily involved in fruit ripening and plant responses to stress, not specifically male functions.

3. **Identifying the Correct Answer:** Among the options, gibberellin is recognized for its role in stimulating the formation of male organs and flowers in plants. Therefore, it is considered the male hormone in plants.

4. **Conclusion:** The male hormone in plants is gibberellin (or gibberellic acid).

**Final Answer:** Gibberellin (Gibberellic Acid)
