How are sperm cells adapted for their function? (AS1)

a) The major function of the sperm is to travel to the egg cell so as to fertilize it.

b) For this, sperm has to travel a large distance in short amount of time. The sperm cell consists of a long tail that helps in its movement.

c) Also, in order to introduce its nucleus into the female cell for fusion, the sperm has to break through the various layers enveloping the egg. For this, acrosome is present on the head of the sperm which releases enzymes that help in dissolving the layers around the egg.
