A haploid plant produces male or female gametes by

Options

A. binary fission
B. mitosis
C. meiosis
D. amitosis

Answer

### Step-by-Step Solution:

1. **Understanding Haploid Plants**:
- A haploid plant has only one set of chromosomes (n). This means that it has half the number of chromosomes compared to diploid organisms (2n).

2. **Gamete Production**:
- Gametes are reproductive cells that fuse during fertilization to form a new organism. In plants, these are typically male (sperm) and female (egg) gametes.

3. **Types of Cell Division**:
- There are different types of cell division: binary fission, mitosis, meiosis, and ametosis. Each has distinct processes and outcomes.

4. **Identifying the Correct Process**:
- **Binary Fission**: This is a form of asexual reproduction primarily seen in unicellular organisms, not applicable to gamete production in plants.
- **Mitosis**: This process results in two identical daughter cells and is used for growth and repair, not specifically for producing gametes.
- **Meiosis**: This is a specialized form of cell division that reduces the chromosome number by half, resulting in four non-identical daughter cells, each with a haploid set of chromosomes. This is the process that produces gametes.
- **Ametosis**: This is a type of cell division that does not involve the formation of a spindle, and it is not relevant to gamete production.

5. **Conclusion**:
- Since haploid plants produce male and female gametes through the process of meiosis, the correct answer is **option c: Meiosis**.
