Model Answer
(a) Placenta: Transfers glucose and oxygen from mother's blood to the embryo, and removes waste substances from embryo to mother's blood.
(b) Fallopian tubes: Carry the egg from the ovary to the uterus; fertilisation of the egg by sperm occurs here.
(c) Uterus: Receives and nurtures the embryo; its lining thickens and is richly supplied with blood to nourish the developing embryo.
(d) Ovary: Produces female germ-cells (eggs) and secretes female reproductive hormones.

Explanation
- The question has four sub-parts worth 2 marks total (~½ mark each), so keep each answer to one concise sentence.
- Examiners look for key function words: transfer nutrition/remove waste (placenta); carry egg/site of fertilisation (fallopian tube); nourish embryo/implantation (uterus); produce eggs/hormones (ovary).
- Avoid repeating the question; go straight to the function. Using terms like "zygote," "implantation," and "villi" where relevant can earn bonus credit.
