Contractile vacuole of Amoeba is found surrounded by

Options

A. many mitochondria
B. few ribosomes
C. few lysosomes
D. many ribosomes and lysosomes.

Answer

To answer the question about what surrounds the contractile vacuole of Amoeba, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Contractile Vacuole**:
- The contractile vacuole is an organelle in Amoeba responsible for osmoregulation, which is the process of maintaining the balance of water and salts in the cell.

2. **Function of the Contractile Vacuole**:
- The primary function of the contractile vacuole is to expel excess water that enters the cell due to osmosis. Amoeba lives in a hypotonic environment (freshwater), where the concentration of water outside the cell is higher than inside, leading to water influx.

3. **Energy Requirement**:
- The process of expelling water requires energy, as the contractile vacuole needs to contract and push out the excess water.

4. **Source of Energy**:
- The energy required for the functioning of the contractile vacuole is provided by mitochondria, which are the powerhouses of the cell, generating ATP (adenosine triphosphate) for cellular activities.

5. **Surrounding Structures**:
- Given that the contractile vacuole requires energy for its function, it is surrounded by many mitochondria to supply the necessary energy.

6. **Conclusion**:
- Therefore, the correct answer to the question is that the contractile vacuole of Amoeba is surrounded by **many mitochondria**.

### Final Answer:
The contractile vacuole of Amoeba is found surrounded by **many mitochondria**.
