Unicellular organisms reproduce by asexual methods like fission, budding while multicellular organisms reproduce by sexual method & asexual method both. For ex. Guava is a multicellular plant that reproduce by vegetative propagation and sexual reproduction.

Methods of contraception :- (i) Use Barriers - It prevents the sperm to reach the egg. For eg. Condoms, Diaphragm. (ii) Chemicals - There are various chemicals or medicines which act by changing the hormonal balance of the body, So that fertilization cannot occur. (iii) Surgical - If vas deferens inRead more

(iii) Surgical – If vas deferens in male or fallopian tube in female is blocked , transfer of sperm or transfer of egg will be prevented respectively.
Advantages of Sexual Reproduction over asexual reproduction are :- (i)It promotes diversity. (ii)It results genetic variations. (iii)It contributes to evolution of species. (iv)It results in origin of new species.

How does the embryo get nourishment inside the mother’s body?
The embryo gets nourishment through placenta inside the mother's body. Placenta is disc-shaped tissue which connects the mother body and embryo.
