Question

What is an early embryo called?

Answer 1

Embryo:

A fertilised egg that attaches to the endometrium and begins maturing to form a foetus is called an embryo.

An early embryo is called a blastula.

Blastula:

1. After fertilization, the zygote undergoes rapid mitotic division which leads to the formation of a structure called blastula or early embryo.
2. In Blastula the cells are arranged in such a manner to form a Hollow mass structure, in which cells are aligned end to end leaving a cavity inside it.
