(ii) The part where the development of the baby takes place.
(iii) The part through which the developing embryo passes to reach the uterus.
b. Explain the future development of the embryo that would take place after it gets embedded in the uterus.

Answer 1

Ovary - (i) The part which produces female gametes.
Uterus- (ii) The part where the development of the baby takes place.
Oviduct - (iii) The part through which the developing embryo passes to reach the uterus.

(b)
The embryo continues to grow and develop after it gets embedded in the uterus. It divides and differentiates into three germ layers which give rise to the different body parts such as hands, legs, head, eyes, ears, etc. This stage where all the body parts are distinct and easily identified in developing embryo is called foetus. A human embryo becomes a foetus after about 8 weeks of pregnancy. After completion of development of foetus (i.e. after about 38 weeks or 9 months), mother gives birth to baby.
