(a) Describe briefly the female reproductive system of a named mammal. (A diagram is essential).
(b) List three differences between reproduction in mammals and in amphibians.
(c) Describe the structure and function of the male reproductive organ of a flowering plant.
Explanation
(a)
The female reproductive system of human consists of two ovaries located below the kidneys. Close to each ovary is the oviductal funnel which lead into the fallopian tube or oviduct. The fallopian tubes are narrow spiralling tubes that lead down into a wider tube called uterus or womb. The two horned uteri join up to form vagina. The narrow lower end of the uteri which lead into the vagina are called the cervix which regulates the opening of the vagina. The urethra opens into the vagina to form a common passage called the vestible which serves as urinogenital tract. This has an opening through vulva?

(c) Description of male reproductive organ of a flowering plant: The male reproductive organ of a flowering plant is known as androecium which is made up of stemens. Stamens are made up of stalks called filaments, which carry the anthers. The anthers are made up of pollen sacs which contain the pollen grains containing the male gametes.
