Non-motile male gametes are produced in

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Male Gametes**: Male gametes are reproductive cells that carry the male genetic material. In most organisms, male gametes are sperm cells in animals and pollen grains in plants.

2. **Defining Non-Motile Male Gametes**: Non-motile male gametes are those that do not have the ability to move on their own. For example, human sperm is motile because it has a flagellum that allows it to swim, while pollen grains do not have such structures and are therefore considered non-motile.

3. **Examples of Non-Motile Male Gametes**:
- In plants, the male gamete is represented by pollen grains. These grains do not move by themselves but can be transported by external agents such as wind, insects, or animals.
- In contrast, in animals, male gametes like sperm are motile.

4. **Analyzing the Options**:
- **Option A: Zia (Maize)**: Produces pollen grains, which are non-motile.
- **Option B: Pysum (Pea Plant)**: Also produces pollen grains, which are non-motile.
- **Option C: Hibiscus**: Produces pollen grains, which are non-motile as well.
- **Option D: All of the above**: Since all the previous options produce non-motile male gametes, this option is correct.

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