Question

Correctly label the following parts of the sperm.

• A. X - Tail, Y - Middle piece, Z - Head
• B. X - Middle piece, Y - Head, Z - Tail
• C. X - Head, Y - Middle piece, Z - Tail
• D. X - Head, Y - Tail, Z - Middle piece

Answer 1

The correct option is C X - Head, Y - Middle piece, Z - Tail

• The topmost part of the sperm has a peculiar shaped head (X) which contains the male genetic material, i.e. all the genetic information necessary to make a young one.
• Just below the head is the middle piece (Y) and it contains mitochondria which provides the energy to the sperm for movement.
• Just beneath the middle piece, there is a long structure called the tail (Z) of the sperm which helps in movement.
