Question

nourishment of growing embryo

Answer 1

After fertilization the lining of uterus thickens and is richly supplied with blood to nourish the growing embryo. The embryo gets nutrition from the mother’s blood with he help of a special tissue called placenta. It is embedded in the uterine wall. Placenta contains Villi on the embryo’s side of the tissue and blood spaces on mother’s side surrounding the villi. This provides a large surface from mother to the embryo and waste products from embryo to mother.

Answer 2

Embryo get its nourishment by attaching firmly to the Uterus of Mother.
There is a connection made between Embryo and Blood vessels of Mother's Uterus' inner lining which is formed after fertilisation.It is called PLACENTA.
It provides a surface to exchange essential food materials to the baby and to get rid of baby's waste.
