Draw a diagram of the microscopic structure of human sperm. Label the following parts in it and write their functions
(c) Middle piece
Draw a diagram of a mature human sperm. Label any three parts and write their functions.
Explain the structure of human sperm with labelled diagram.
Structure of human sperm
Function of Acrosome-It releases various chemicals like hyaluronidase and acrosin which helps sperm in fusing with egg cell.
Function of Nucleus-It stores the genetic information. It carries 23 chromosomes, out of which one is sex chromosome (either X or Y). Thus, it is responsible for determining the sex of the individual.
Function of Middle piece-The middle piece contains several mitochondria, which produce energy for the motility of the sperm.
- Head: It the flat oval part of the human sperm that contains the nucleus, containing genetic material, and acrosome, a small anterior part which is formed from Golgi complex. It secretes hyaluronidase enzyme which helps in the entry of sperm into the egg.
- Middle Piece: It is the middle, cylindrical portion of the sperm, which contains numerous mitochondria. They provide energy (ATP) to the sperm for its movement.
- Tail: It is the long, tapering structure composed of cytoplasm. It helps in the movement of the sperms inside the uterus.
