Zygotic meiosis occurs in

Options

A. Pinus
B. Marchantia
C. Chalmydomonas
D. Dryopteris

Answer

**Step-by-Step Solution:**

1. **Understanding Zygotic Meiosis:**
- Zygotic meiosis is a type of meiosis that occurs immediately after the formation of the zygote. In this process, the zygote undergoes meiosis to produce haploid spores.

2. **Identifying Organisms that Exhibit Zygotic Meiosis:**
- Zygotic meiosis is primarily observed in certain algae. In these organisms, the sporophyte does not produce spores directly; instead, the zygote formed after fertilization undergoes meiosis to create spores.

3. **Analyzing the Options:**
- The options provided are:
- A) Pinus
- B) Marchantia
- C) Calamogrostis
- D) Diopteris
- Pinus (a gymnosperm) and Marchantia (a liverwort) do not exhibit zygotic meiosis. Diopteris (a fern) also does not follow this pattern.

4. **Identifying the Correct Answer:**
- Calamogrostis is a green algae that undergoes zygotic meiosis. In this organism, the zygote is diploid and undergoes meiosis to produce haploid spores, which can then develop into gametes.

5. **Conclusion:**
- Therefore, the correct answer to the question "Zygotic meiosis occurs in" is option C) Calamogrostis.
