The cells, those aggregate to form internal buds during asexual reproduction in sponges are :-

Options

A. Archaeocytes
B. Pinacocytes
C. Interstitial cells
D. Choanocytes

Answer

To answer the question regarding which cells aggregate to form internal buds during asexual reproduction in sponges, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction in Sponges**:
- Sponges can reproduce asexually through processes such as budding or fragmentation. In this context, we focus on the formation of internal buds.

2. **Identifying the Type of Asexual Reproduction**:
- The specific type of asexual reproduction in sponges that involves the formation of internal buds is called gemmulation.

3. **Role of Cells in Gemmulation**:
- During gemmulation, certain cells aggregate to form these internal buds.

4. **Identifying the Specific Cells**:
- The cells that aggregate to form these internal buds are known as archaeocytes (or amoebocytes). These cells are capable of differentiating into various cell types and play a crucial role in the sponge's regeneration and reproduction processes.

5. **Conclusion**:
- Therefore, the cells that aggregate to form internal buds during asexual reproduction in sponges are **archaeocytes**.

### Final Answer:
The cells that aggregate to form internal buds during asexual reproduction in sponges are **archaeocytes**.
