MICROANATOMY

Detailed explanation-1: -The head of the sperm contains the DNA, which when combined with the egg’s DNA, will create a new individual. The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg.

Detailed explanation-2: -The head is covered by the ac cap and contains a nucleus of dense genetic material from the 23 chromosomes. It is attached from the neck to the body containing mitochondria that supply the energy for the sperm’s activity.

Detailed explanation-3: -Sperm usually consist of two morphologically and functionally distinct regions enclosed by a single plasma membrane: the tail, which propels the sperm to the egg and helps it to burrow through the egg coat, and the head, which contains a condensed haploid nucleus (Figure 20-25).

Detailed explanation-4: -Yes, sperm cells contain DNA. The male gamete, also known as a sperm cell, contains half the genetic material for the offspring. This is found in 23 chromosomes which will pair with the 23 chromosomes from the female gamete, the egg cell.
