Question

Foetal membranes provide

• A. Protection to embryo
• B. Nutrition to embryo
• C. Protection and nutrition to embryo
• D. None of the above

Answer 1

The correct option is C Protection and nutrition to embryo

There are four fetal membranes and they are as follows :
Amnion: Protects the embryo from desiccation in the sac filled with amniotic fluid.
Yolk sac: Contains yolk which is the source of food.
Chorion: Lines the inner surface of the shell which is permeable to gases and allows the exchange of oxygen and carbon dioxide.
Allantois: Stores metabolic wastes of the embryo.
So, fetal membrane provides protection (amnion) as well as nutrition (yolk sac) to the embryo.
Thus, the correct answer is C.
