Question

What are the three steps of development that a fertilized egg goes through before birth?

Answer 1

A fertilized egg goes through three stages of development before birth: the germinal stage, the embryonic stage, and the fetal stage.

Step-by-step explanation:

In prenatal development, a fertilized egg goes through three stages before birth: the germinal stage, the embryonic stage, and the fetal stage.

1. The germinal stage lasts for the first two weeks after fertilization and involves processes such as fertilization, cleavage, blastulation, and implantation.
2. The embryonic stage starts at implantation and lasts until the eighth week after fertilization. During this stage, significant growth and changes occur, including gastrulation, neurulation, and organogenesis.
3. The fetal stage begins after the embryonic stage and lasts until birth. In this stage, the developing embryo is referred to as a fetus and undergoes rapid growth and maturation of organs and body systems.
