Answer: Sperm cell

Step-by-step explanation:

Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.

  • A somatic cell is the one which forms the body of an organism and contains all the genetic information.
  • A gamete is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
  • A Sperm cell is basically a male gamete. It contains only half the amount of genetic information as the other half is contributed by the female gamete.
  • This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
  • During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the complete genetic information.
  • During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each with half the amount of genetic material as present in the parent cell.

Since, sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.
