Question

What purpose does the tail in sperm serve?
A. To swim to the egg
B. To provide direction
C. To carry genetic material
D. None of the above

Answer 1

Hint: Most animals generate sperm, also known as spermatozoon, a male reproductive cell. Sperm are flagellated, which means they have a whiplike tail, with the exception of nematode worms, decapods, diplopods, and mites. Sperm is produced in the testes of higher vertebrates, particularly mammals. The sperm combines with the female's ovum to create a new child. There are two distinct pieces to mature sperm: a head and a tail.

Complete answer:
Option A: The acrosome, which is located at the tip of the sperm head, allows the sperm to penetrate the egg. The mitochondria in the midpiece provide the energy required for the tail to move. To drive the sperm towards the egg, the tail makes whip-like movements back and forth.
So, option A is correct
Option B: The sperm tail is provided to allow for easy and rapid movement of the sperm so that it can swim to and unite with the egg.
So, option B is not correct
Option C: head is used to carry the genetic material.
So, option C is not correct.
Option D: The tail of sperm serves as a propulsion system. It aids sperm in reaching and fertilising the ovum by allowing them to travel through the female reproductive canal.
So, option D is not correct.

Hence, Option A is the correct answer.

Additional information:
Spermatogenesis is the process of male gametes, often known as sperm, forming in the testes, the male reproductive organs. Each sperm (haploid, containing a single copy of each chromosome) is used in this process. A cell goes through the process of meiosis, which involves the replication and division of the genome twice to produce four haploid gametes.

Note:
Structure of human sperm-
Acrosome apically is found in the head, and it includes enzymes that help sperm enter the ovum. It is followed by a nucleus that is elongated (haploid)
Multiple mitochondria can be found in the middle portion, which give energy for sperm motility.
The sperm tail is a flagellum that protrudes from the cell body and is responsible for sperm motility. The tail aids sperm in swimming, allowing them to reach the ovum.
Approximately \[200 - 300\] million sperm are ejected all at once.
