Which statement below is an example of how a gamete's structure significantly helps its function?

Eggs have tails to help them travel down the fallopian tubes to the uterus.

Sperm have a well-protected head and a motor to help them travel.

Eggs are small to minimize their chances of double fertilization.

Sperm are large so that they can contain nutrients for the developing embryo.

Sperm have a well-protected head and a motor to help them travel.

Explanation:

Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.

- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.
