Key Stage 3

Meaning

Gestation is the period of time while offspring is developing in the uterus of a mammal.

About Gestation

Gestation starts with conception and ends with birth of the offspring.

The offspring goes through several stages of development.


After fertilisation the ovum divides into two cells, then four cells.	This embryo has many cells that have not yet been given a specific job.

The cells in this embryo are being assigned specific jobs as it starts to look more like a human.	Once all the cells have been given their specific jobs it is called a foetus. A this point the offspring is preparing to live outside the uterus.
