Question

Answer

Unisexual Organism

A unisexual organism is an organism that has only one sex, either male or female. These organisms are also known as unisexual or gonochoric organisms. In unisexual organisms, reproduction occurs through the fusion of gametes produced by separate male and female individuals.

Example

The cockroach is an example of a unisexual organism. Cockroaches are dioecious, meaning that there are separate male and female individuals. The male cockroach has a pair of testes that produce sperm, while the female cockroach has ovaries that produce eggs. Fertilization occurs when the male deposits sperm into the female's reproductive tract.

Other Options

a) Earthworm - Earthworms are hermaphrodites, meaning that they have both male and female reproductive organs. They can mate with another earthworm to exchange sperm and fertilize each other's eggs.

c) Tapeworm - Tapeworms are also hermaphrodites. They have both male and female reproductive organs and can self-fertilize.

d) Leech - Leeches are hermaphrodites, and they can also reproduce through asexual reproduction by budding.

Answer

Cockroach is an example of a unisexual organism, which means it can produce only one type of gamete, either male or female. Leech, tapeworm and earthworm are bisexual organisms, organisms that can produce both gametes.
