In Chlamydomonas, meiosis occurs in

Options

A. Gamete
B. Zygote
C. Sporogonium
D. Zoo spore

Answer

### Step-by-Step Solution:

1. **Understanding the Organisms**: Chlamydomonas is a unicellular green alga that reproduces both sexually and asexually.

2. **Identifying the Options**: The options provided are:
- Gamete
- Zygote
- Sporogonium
- Zoospore

3. **Analyzing Gametes**:
- Gametes are haploid cells (n) that fuse during fertilization to form a zygote.
- Since gametes are already haploid, meiosis cannot occur in them. Therefore, this option is incorrect.

4. **Analyzing Zygote**:
- A zygote is formed by the fusion of two haploid gametes, resulting in a diploid cell (2n).
- Meiosis can occur in the zygote because it is diploid, making this option a potential answer.

5. **Analyzing Sporogonium**:
- Sporogonium refers to a structure that produces spores.
- In Chlamydomonas, meiosis does not occur in sporogonium, so this option is also incorrect.

6. **Analyzing Zoospore**:
- Zoospores are asexual reproductive cells that are also haploid.
- Since they are haploid, meiosis cannot occur in zoospores, making this option incorrect as well.

7. **Conclusion**:
- After analyzing all the options, the only structure where meiosis occurs in Chlamydomonas is the **zygot**e. Therefore, the correct answer is **zygot**e.

### Final Answer:
In Chlamydomonas, meiosis occurs in the **zygot**e.
