The zygote lasts for four days. On the fifth day, the cells become known as a blastocyst. The period will last for approximately two weeks, after this period of time the organism is known as an embryo;
The Embryo:
An Embryo is a fertilized egg that has begun cell division. An embryo grows arms and legs and begins to develop fingers and toes as it develops into a foetus it. In the eight week of pregnancy the embryo begins to form lungs, and its brain continues developing. At this stage, the embryo is very small, at less than 0.75 of an inch long.

The baby may relax and become still to slower sounds and more energised when hearing high sounds. A baby will also usually stop crying to listen to a voice by two weeks old. Every baby is born with tiny taste buds; babies therefore enjoy sweet tastes such as breastmilk. A baby can also focus on an object 20cm away from them. The baby will also enjoy looking at human faces and tracking movements of people and
