The different stages of prenatal development are as follows:

1. Germinal Stage: This stage begins at conception and lasts for about two weeks. During this stage, the fertilized egg, called a zygote, undergoes rapid cell division and travels down the fallopian tube to the uterus. The zygote eventually implants itself into the uterine wall.

2. Embryonic Stage: This stage occurs from the third week to the eighth week of pregnancy. During this time, the zygote is now called an embryo. Major organs and body systems begin to form, and the embryo is most vulnerable to external factors that can cause birth defects.

3. Fetal Stage: This stage begins at the ninth week and continues until birth. The developing organism is now called a fetus. During this stage, the organs and body systems continue to develop and mature. The fetus also undergoes rapid growth and refinement of its features.

Throughout these stages, prenatal development involves various processes such as cell division, cell differentiation, and organ formation. It is important for expectant mothers to take care of their health and avoid harmful substances to ensure the healthy development of the fetus. Regular prenatal check-ups and proper nutrition are also crucial during this time.
