Meiosis in plant occurs, when there is a change from

Options

A. Gametophyte to sporophyte
B. Sporophyte to sporophyte
C. Sporophyte to gametophyte
D. Gametophyte to gametophyte

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms:**
- Define the two main stages in the plant life cycle: **Sporophyte** and **Gametophyte**.
- **Sporophyte**: This is the diploid (2n) phase of the plant, which means it has two sets of chromosomes.
- **Gametophyte**: This is the haploid (n) phase of the plant, which means it has one set of chromosomes.

2. **Identifying the Process of Meiosis:**
- Meiosis is a type of cell division that reduces the chromosome number by half. It is referred to as a **reduction division**.
- In plants, meiosis occurs to produce haploid spores from diploid cells.

3. **Determining When Meiosis Occurs:**
- In the plant life cycle, meiosis occurs when the sporophyte (diploid) generation produces spores that develop into gametophytes (haploid).
- Therefore, the transition from **Sporophyte to Gametophyte** is where meiosis takes place.

4. **Analyzing the Options:**
- The options given are:
- Gametophyte to Sporophyte
- Sporophyte to Sporophyte
- Sporophyte to Gametophyte
- Gametophyte to Gametophyte
- Based on our understanding, the only correct transition that involves meiosis is **Sporophyte to Gametophyte**.

5. **Conclusion:**
- Hence, the answer to the question is that meiosis in plants occurs when there is a change from **Sporophyte to Gametophyte**.
