Question

5. Suppose the tails of sperms are detached in an experiment. Will these speres participate
in fertilization ? Explain.​

Answer 1

The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg. The midpiece contains the mitochondria which supplies the energy the tail needs to move. The tail moves with whip-like movements back and forth to propel the sperm towards the egg.
