Question

Where is acrosome present in humans? Write its function.

Answer 1

In humans, sexual reproduction takes place due to the fusing of male gametes that is sperm cells and female gametes that is ovum. After the sperm ejaculation inside the female, the sperm cell swims towards the egg for fusion.

Complete answer:
To answer this question, we have to know about the sperm cells. The sperm cells are male gametes that formed inside the testicular organs or gonad of males. The sperm cells carry 23 chromosomes, the same as that of the female gametes that is formed due to the meiosis process. This cell is involved during the sexual reproduction among the humans and other animals.
So, the sperm cell comprises a distinctive head, mid piece that is also called body, and the tail. The head of the sperm cell is oval and smooth, it resembles an egg because of its tapering apex and broad base. It consists of the nucleus that has the genetic materials that are required for the formation of a new organism. Apart from this the sperm head is also made up of acrosome and acrosomal cap.

Now, the acrosome and acrosomal cap together form the acrosomal region that produces spermiogenesis. The acrosomal matrix consists of acrosin enzymes and also monosaccharides. It is found in the space between the nuclear membrane and the interior cell membrane. Therefore, acrosome is the cap-like structure found in the tip of the sperm of male human. It involves the fertilization of the ovum by dissolving the wall of the ovum and making passage for the nucleus of the sperm to enter the ovum.

Note: The mid piece found between the head and the tail part of a sperm cell comprises mitochondria that provide energy for the swimming of sperm when it moves towards the female gametes. The tail helps in the movement of the sperm cell.
