Gametogenesis in haploid plants involves
(a) Binary fission
(b) Meiosis
(c) Mitosis
(d) Amitosis

Options

A. Binary fission
B. Meiosis
C. Mitosis
D. Amitosis.

Answer

To solve the question regarding gametogenesis in haploid plants, we will analyze each option provided:

### Step-by-Step Solution:

1. **Understanding Gametogenesis**:
- Gametogenesis is the process of forming gametes (sperm and egg cells). In haploid organisms, gametes are produced from cells that have a single set of chromosomes (N).

2. **Evaluating Option A - Binary Fission**:
- Binary fission is a form of asexual reproduction where a single organism divides into two parts. This process does not involve the formation of gametes, so it is not applicable to gametogenesis.
- **Conclusion**: Option A is incorrect.

3. **Evaluating Option B - Meiosis**:
- Meiosis is known as reduction division, where the chromosome number is halved. In haploid organisms, they already have one set of chromosomes (N). If meiosis were to occur, it would reduce the chromosome number further, which is not possible.
- **Conclusion**: Option B is incorrect.

4. **Evaluating Option C - Mitosis**:
- Mitosis is an equational division where the chromosome number remains the same. In haploid plants, mitosis can occur to produce gametes, maintaining the haploid state (N). This is the process that leads to the formation of gametes in haploid plants.
- **Conclusion**: Option C is correct.

5. **Evaluating Option D - Amitosis**:
- Amitosis is a type of cell division that involves only nuclear division without cytoplasmic division. This process does not lead to the formation of gametes, making it irrelevant for gametogenesis.
- **Conclusion**: Option D is incorrect.

### Final Answer:
The correct answer is **(c) Mitosis**.
