Press a sponge through a coarse cloth bag and extrude the whole cells through the holes. The cells then :

Options

A. reproduce sexually
B. die from being separated
C. form spicules in the pattern of the cloth
D. reassemble into a new organised sponge with each cell resuming its original job

Explanation

To solve the question regarding what happens to sponge cells when they are pressed through a coarse cloth bag, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Sponges**:
- Sponges belong to the phylum Porifera, which are known for their porous bodies. They are aquatic organisms that can be found in marine and freshwater environments.

2. **Identify the Types of Cells in Sponges**:
- Sponges have different types of cells, including archaeocytes, which are totipotent. This means they can transform into other types of cells as needed.

3. **Consider the Process of Extrusion**:
- When you press a sponge through a coarse cloth bag, you are forcing the cells out through the holes. This process separates the cells from their original structure.

4. **Evaluate the Options Provided**:
- **Option A**: "Reproduced sexually" - This is incorrect as sexual reproduction requires gamete formation, which cannot happen just by pressing the sponge.
- **Option B**: "Die from being separated" - This is also incorrect because sponges have a remarkable ability to regenerate.
- **Option C**: "Forms speckles in the pattern of the cloth" - This is not relevant to the biological function of the cells.
- **Option D**: "Reassembled into organized sponge with each cell resuming its original job" - This is correct. The totipotent cells can reorganize and take on their original functions.

5. **Conclusion**:
- After evaluating all options, the correct answer is **D**: The cells will reassemble into an organized sponge with each cell resuming its original job due to their regenerative capabilities.
