Question

3 differences between internal and external fertilisation.

Answer 1

Answer:

Internal is better because it is more secure for the baby to be born, and live a full life. It's better for the baby when it is born to be protected by the parents. It lives on land, so now there is a better chance for for the egg to actually fertilize.

Explanation:

External fertilization is when the male and female's gametes unite outside the female's body. Internal fertilization occurs inside the body, whereas external fertilization happens outside the body. Fertilization is the process by which a sperm cell and an egg cell unite to form a completely new individual.

Answer 2

Explanation:

Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.

Internal fertilization is followed by mammals, birds, while external fertilization is supported by mostly aquatic animals and few amphibians.

We all are aware of the word fertilization, which defines the union of sperm (male gamete) and egg nucleus (female gamete) to produce diploid cell or zygote, which further develops or grow into the young ones of their generation. Internal and External fertilization are the two types of fertilization, which takes place among various groups of animals, and with this content, we will be discussing the diverse features of them.
