Power of regeneration in sponges is due to

Options

A. Amoebocytes
B. Archaeocytes
C. Scleroblasts
D. Thesocytes

Answer

### Step-by-Step Solution:

1. **Understanding Regeneration in Sponges**:
- Regeneration is the ability of an organism to replace lost or damaged cells and tissues. In sponges, this ability is quite remarkable.

2. **Identifying Key Cell Types**:
- To understand the power of regeneration in sponges, we need to identify which cells are responsible for this process. The main cell types involved in regeneration are:
- **Amibocytes**: These cells are found near pseudopodia and are known for their totipotent nature, meaning they can develop into various cell types.
- **Archeocytes**: These are also totipotent cells and play a significant role in regeneration. They can develop into any type of cell needed for repair and are involved in digestion as well.
- **Scleroblasts**: These cells contribute to the formation of the sponge's skeletal structure but do not play a role in regeneration.
- **Thesocytes**: These cells store food and assist in nutrient distribution but are not directly involved in regeneration.

3. **Determining the Correct Cell Type**:
- Among the mentioned cells, **Archeocytes** are the most crucial for regeneration in sponges. They can transform into any cell type required for the sponge's repair and regeneration processes.

4. **Conclusion**:
- The power of regeneration in sponges is primarily due to **Archeocytes**, as they are the totipotent cells responsible for forming new cells after damage.

### Final Answer:
The power of regeneration in sponges is due to **Archeocytes**.
