Non-motile male gametes are produced in

Options

A. Zea
B. Pisum
C. Hibiscus
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks where non-motile male gametes are produced. Non-motile male gametes are those that cannot move independently.

2. **Define Non-Motile Male Gametes**: Non-motile male gametes are typically represented by pollen grains in plants. Unlike sperm cells in animals, which are motile due to their flagella, pollen grains do not have the ability to move on their own.

3. **Identify Examples**:
- **Pollen Grains**: These are the male gametes in flowering plants (angiosperms). They are produced in the anthers of flowers and are carried by wind, insects, or water to the female reproductive parts.
- **Other Examples**: In some plants, such as those in the genus *Zea* (corn), *Pisum sativum* (peas), and *Hibiscus*, pollen grains are also produced as non-motile male gametes.

4. **Evaluate the Options**:
- Option A: *Zea* - Produces pollen grains (non-motile).
- Option B: *Pisum sativum* - Produces pollen grains (non-motile).
- Option C: *Hibiscus* - Produces pollen grains (non-motile).
- Option D: "All of these" - Since all the options A, B, and C produce non-motile male gametes, this option is correct.

5. **Conclusion**: The correct answer is option D: All of these, as all the listed organisms produce non-motile male gametes.
