Question

What is zygote? Differentiate between external fertilisation and internal

fertilisation.​

Answer 1

Answer:

a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.

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.

Answer 2

Answer:

A zygote is a eukaryotic cell formed by a fertilization event between two gametes.Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

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.
