Question

The two structures shown below are formed in the process of spermatogenesis. Study them carefully and answer the questions that follow.

1. Identify the process which converts Structure A to Structure В.
2. State any two modifications observable in Structure B.

Answer 1

1. The process which converts Structure A to Structure B is Spermiogenesis.
2. Two modifications in Structure B are as follows:
   1. Tail (Flagellum) Formation: From the centriole, a long flagellum that provides mobility develops.
   2. Acrosome Formation: At the head, the Golgi apparatus transforms into a cap-like acrosome that contains hydrolytic enzymes necessary for fertilization, such as hyaluronidase.
