Disappearance of the tadpole tail during metamorphosis is brough about by

Options

A. Lysosomes
B. Golgi apparatus
C. Peroxisomes
D. Endoplasmic reticulum

Answer

### Step-by-Step Solution

1. **Understanding Metamorphosis**:
- Metamorphosis is a biological process where an animal undergoes significant physical changes after hatching or birth. In the case of frogs, this process includes the transformation from a tadpole to an adult frog.

2. **Identifying the Role of Lysosomes**:
- During the metamorphosis of a tadpole, specific cellular structures play crucial roles. Lysosomes are organelles that contain digestive enzymes capable of breaking down various biomolecules.

3. **Function of Lysosomal Enzymes**:
- The lysosomes contain enzymes such as cathepsin, which are responsible for degrading proteins and polypeptides. This degradation is essential for the removal of the tadpole's tail.

4. **Mechanism of Tail Disappearance**:
- As the tadpole undergoes metamorphosis, the lysosomal enzymes break down the proteins in the tail, leading to its gradual disappearance. This process is a vital part of the transformation from a tadpole to a frog.

5. **Conclusion**:
- Therefore, the disappearance of the tadpole tail during metamorphosis is primarily due to the action of lysosomes and their enzymes.

### Final Answer
The disappearance of the tadpole tail during metamorphosis is brought about by lysosomal action.
