Best Answer

Ans. (i) Fertilisation takes place in fallopian  tube (oviduct).

(ii) Implantation of the fertilised egg occurs in the uterus.

Nourishment of embryo. After fertilisation, zygote  is formed which  develops into an embryo. The embryo gets nutrition from the mother's blood with the help of a special tissue  called   placenta. This  is  a  disc  which   is  embedded  in  the  uterine wall.  It contains villi on the embryo's side of the tissue.  On the mother's side are blood spaces, which surround the villi. This provides a large surface area for glucose  and oxygen  to pass from the mother to the embryo. In this way, embryo gets its nutrition
