In plants, the process of gamete formation involves

Options

A. mitosis
B. meiosis
C. both mitosis and meiosis
D. no cell division

Answer

To solve the question regarding the process of gamete formation in plants, we can break it down into the following steps:

### Step-by-step Solution:

1. **Understanding Gamete Formation**: In plants, gamete formation is primarily associated with the reproductive structures, which involve both male and female gametes.

2. **Meiosis in Gamete Formation**: The first key process involved in gamete formation is **meiosis**. This is a type of cell division that reduces the chromosome number by half, resulting in haploid cells.

3. **Formation of Female Gametes**:
- In the female part of the plant, the **megaspore mother cell** (also known as megasporocyte) undergoes meiosis.
- This process results in the formation of a single haploid egg cell from the megasporocyte.

4. **Formation of Male Gametes**:
- In the male part of the plant, the **microspore mother cell** (or microsporocyte) also undergoes meiosis.
- This division produces four haploid male gametes (pollen grains).

5. **Fertilization Process**:
- When the male and female gametes fuse during fertilization, a diploid zygote is formed.
- This zygote will then undergo mitosis to develop into an embryo.

6. **Conclusion**: Therefore, the processes involved in gamete formation in plants are **meiosis** (for the formation of haploid gametes) and **mitosis** (for the development of the zygote into an embryo).

### Final Answer:
In plants, the process of gamete formation involves **meiosis** and **mitosis**.
