The correct Answer is:
To determine where meiosis takes place, let's analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding Meiosis**: - Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid cells from a diploid cell. It is crucial for sexual reproduction as it produces gametes (sperm and eggs). 2. **Analyzing Option A: Gemmule**: - A gemmule is a vegetative structure that is involved in asexual reproduction. It does not undergo meiosis, as it does not produce gametes. Therefore, meiosis does not take place in gemmules. 3. **Analyzing Option B: Megaspore**: - A megaspore is produced from a megaspore mother cell through the process of meiosis. However, the megaspore itself is the product of meiosis, not the cell where meiosis occurs. Thus, meiosis does not take place in megaspores. 4. **Analyzing Option C: Meiocyte**: - A meiocyte is a diploid cell that is capable of undergoing meiosis to produce haploid gametes. Since meiocytes are specifically designated for the process of meiosis, this is the correct answer. 5. **Analyzing Option D: Conidia**: - Conidia are asexual spores that are typically haploid. Since meiosis is a process that occurs in diploid cells, meiosis does not take place in conidia. ### Conclusion: The correct answer is **C. meiocyte**, as it is the only option where meiosis occurs. ---
