Question

What Are Formed During The Development Of Embryo?

Answer 1

Some of the cells from the placenta develop into an outer layer of membranes (chorion) around the developing blastocyst. Other cells develop into an inner layer of membranes (amnion), which form the amniotic sac. When the sac is formed (by about day 10 to 12), the blastocyst is considered an embryo.

Answer 2

Answer:

your answer

Fertilisation results in the formation of zygote. The zygote divides repeatedly to give rise to a ball of cells which then begin to form groups that develop into different tissues and organs of the body. This developing structure is called an embryo. It gets embedded in the wall of the uterus for further development.
