Acrosome of sperm is formed from which part of the spermatid?

Acrosome of sperm is formed from which part of the spermatid? Correct Answer Golgi body

Concept:

• Sperm is the male gamete. The sperm unites with (fertilizes) an ovum (egg) of the female to produce a new offspring.
• A sperm has three main parts:

1. The head of the sperm contains an elongated haploid nucleus, which holds the DNA of the cell and the anterior portion is covered by a cap-like structure acrosome.
2. The midpiece of the sperm is packed with mitochondria. Mitochondria are organelles in cells that produce energy. Sperm use the energy in the midpiece to move.
3. The tail of the sperm moves like a propeller, around and around. This tail is a long flagellum that pushes the sperm forward.

• Spermatids is haploid cells formed by meiotic division of spermatocytes and develops into a spermatozoon after maturational events.

Explanation:

• The acrosome is a membrane-bound structure formed from the Golgi apparatus located most anteriorly in the head of the sperm, It is a cap-like structure. The acrosome of sperm helps in penetration of sperm into the ovum. The acrosome carries hyaluronidase enzyme for penetration of egg.
• Mitochondria are organelles in cells that produce energy. Sperm use the energy in the midpiece to move.
• sperm has very less quantity of Ribosome.

Additional Information

• Seminal plasma along with sperm constitutes the semen.
• The process of formation of sperms is called spermatogenesis. It involves 3 phases:
• In multiplication phase, male germ cells also called spermatogonia undergo mitotic divisions to form a large number of spermatogonia.
• In the growth phase, spermatogonia increase their size by the accumulation of nutrition in the cytoplasm and are ready for meiotic division and the spermatocytes are called primary spermatocytes with 46 chromosomes.
• In maturation phase, primary spermatocyte completes the first meiotic division-leading formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each and the secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids.
