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. The midpiece contains the mitochondria which supplies the energy the tail needs to move.
Detailed explanation-2: -The head of the sperm cell contains the male’s genetic information that is to be passed on to the next generation. Normally, the head of a sperm cell contains one copy of each chromosome .
Detailed explanation-3: -The acrosome is a specialized sperm organelle that contains digestive enzymes and covers the sperm head, which continues to surprise us with new findings (Zhang et al., 2020; Wang et al., 2020).
Detailed explanation-4: -The sperm cells have only 23 chromosomes, or half of the usual number. When a sperm cell unites with the ovum, which also has 23 chromosomes, the resulting 46 chromosomes determine the offspring’s characteristics. The sperm cells also carry the X or Y chromosome that determines the sex of the future child.
Detailed explanation-5: -The mature sperm cell (spermatozoa) is 0.05 milliliters long. It consists of a head, body and tail. The head is covered by the ac cap and contains a nucleus of dense genetic material from the 23 chromosomes.
