Question

How is an embryo developed?

Answer 1

Answer:

Each embryo starts development as a zygote, a single cell resulting from the fusion of gametes (i.e. fertilization of a female egg cell by a male sperm cell). ... Next, the cells in a blastula-stage embryo start rearranging themselves into layers in a process called gastrulation.

Answer 2

${\huge{\underline{\underline{\mathfrak{\pink{Answer:-}}}}}}$

Fertilisation results in the formation of zygote. The zygote divides repeatedly to give rise to a ball of cells which then begin to form groups that develop into different tissues and organs of the body. This developing structure is called an embryo. It gets embedded in the wall of the uterus for further development.
