In short, an embryo undergoes both cellular division and cellular differentiation to become a fetus. This is achieved by the genetic program present in the cell(s) which controls both mentioned processes. It is the stage of developing mammal.After 9th week of fertilisation,the embryo can be called foetus.
After 8 weeks
An embryo during the late stages of development is known as a fetus.
An embryo makes blood because it begins to develop into a fetus and later into a new infant. An egg can not become an embryo without the DNA that the sperm donates.
The development of a fertilized egg starts out as an embryo though after 8 weeks it is legally considered a fetus.

The fetus
fertilized egg,embryo, and fetus
There really isn't much difference between a zygote, embryo, and fetus. A zygote forms after fertilization and becomes an embryo, which later becomes a fetus.
In humans, the embryo becomes the fetus at the beginning of the 11th week in gestational age (the 9th week after fertilization). This stage starts when the major structures have formed.
