Olympiad Test: Reproduction In Animals

The fusion of male and female gamete is called fertilization. Internal fertilization takes place in humans. Male releases sperms inside female's body. Sperms and ovum fuse together in fallopian tube, during fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus.

A sperm is a germ cell. It is one of two types of reproductive cells found in sexually reproducing animals. Sperm is produced by males. It consists of three parts. i.e  Head, middle, tail.

A foetus is the unborn offspring of an animal that develops from an embryo. In human prenatal development, fetal development begins from the ninth week after Fertilisation  and continues until birth. 

Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. Organisms such as hydra use regenerative cells for reproduction in the process of budding. 

Amoeba can't reproduce by the process of budding.

Earthworms are Simultaneous hermaphrodite, meaning worms have both male and female reproductive organs. During sexual intercourse among earthworms, both sets of sex organ are used by  both worms.
Earthworms only reproduce through sexual reproduction.
So, the given statement is false.

In- vitro fertilization ( IVF) can help to achieve pregnancy when other treatments have not worked. The process involves fertilizing an egg outside the body, and implanting it to continue the pregnancy.
