Question

How is fetus different from embryo?

Answer 1

Fetus and embryo are different from each other in reference to their degree of development. After fertilization of the male and female gametes, a zygote is formed which divide to form an embryo in which the cells organize themselves into the order of their development. After the 9${}^{th}$ week until the end of the gestation period, the developing embryo is regarded as a fetus.
