Atadpole will lose its tail as it grows into an adult. which cell structures in the tail of a tadpole cause this change to occur?

The correct answer will be- lysosomes.

Explanation:

Tadpole loses its tail by 9-10th week after the fertilization process has taken place. At this time, the tadpole loses its tail through the process of apoptosis.

The organelle which plays an important role in the apoptosis is lysosomes which contain the hydrolytic enzymes. The lysosomal proteases like aspartic protease and the cysteine cathepsins  present in the lysosomes gets released into the cytosol where they act as the mediators of the apoptosis in the tadpole tail.

Thus, lysosomes are the correct answer.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
