Draw a neat well labelled digram of the human sperm. Also,write how its shape and size help it in its functioning

Answer:
The sperm cells are the haploid gametes which are produced in the male. There are different parts of the sperm cell.
The sperm cells are the haploid gametes which are produced in the male. There are different parts of the sperm cell. (a) Acrosome: This structure contains enzymes used for penetrating the female egg.

(c) Middle piece: The middle piece has a central filamentous core with many mitochondria spiralled around it which is used for ATP production for the journey through the female cervix, uterus and uterine tube.

Answer:
mature human sperm cell has snake like structure. It has following parts - head, neck, middle piece and tail.
Head: It is spherical in shape consisting of large nucleus and a dome shaped acrosome present on the nucleus.
Function: Nucleus contain genetic information and half number of chromosomes. The acrosome releases a hyaluronidase enzyme which destroys the hyaluronic acid of the ovum and enters into the ovum.
Neck: It contains centrioles which are proximal centriole and distal centriole.
Function: Distal centriole gives rise to axial filament of the sperm which runs up to the end of the tail.
Middle piece: It is tubular structure in which mitochondria are spirally arranged.
Function: Middle piece is called power house of sperm because it gives energy to the sperm to swim in the female genital tract.
Tail: It arises from middle piece and it is the end part of the sperm. It contains axial filaments.
Function: Tail helps the sperm to swim in the female genital tract. It is the main part of sperm to move.
