Question

The animals that consist of both male and female sex organs are known as
A) Viviparous
B) Oviparous
C) Sterile
D) Hermaphrodite

Answer 1

Hint: The unisexual organisms are the organisms which has either male or female reproductive parts. The bisexual organisms have both male and female sexual organs. An example of a bisexual organism is snail, slug.

Complete answer:
The sex organs are the organs which take part in reproduction. It is an essential organ of the plant and animal. The animals mostly have two sexes -Males in which only male sex organs are present which produces male gametes and female which has only female sex organs and produce female gametes. The fertilisation takes place in the female body called the internal fertilisation or can occur externally.

In some organisms both the sex organs are present in a single organism. These organisms are known as hermaphrodite. They are capable of producing organisms of their own. Example of bisexual organisms’ fishes, snail, snugs etc.

Viviparous- The animals which do not lay eggs but give birth to the young ones are called viviparous animals. The fertilisation is internal and the offspring develop inside the body of the parent. Example mammals, humans.

Oviparous- The animal which lays eggs is known as oviparous. The eggs develop into young ones. Example birds.

Sterile- The animals which are capable of mating but are not able to create offspring are called sterile animals. Example many hybrids like mules.

Thus the correct answer is option “D”.

Note: The sexual development in mammals occurs in the womb. It is rare in mammals. There are several species which are naturally born as hermaphrodites. They continue to remain as hermaphrodites for the entire life.
