Match the following. 

(i)	Ovary	(a)	fertilisation
(ii)	Oviduct	(b)	implantation
(iii)	Uterus	(c)	nourishes the growing embryo
(iv)	Placenta	(d)	makes the female gametes

The correct answer is i - d, ii - a, iii - b, iv - c.

Key Points

• Ovary (i) - makes the female gametes (d): The primary function of the ovary is to produce the female gametes, also known as ova or eggs. It also secretes hormones such as estrogen and progesterone.
• Oviduct (ii) - fertilisation (a): The oviduct, also known as the fallopian tube, is the site where fertilisation occurs. The sperm meets the egg in the oviduct to form a zygote.
• Uterus (iii) - implantation (b): The uterus is the organ where the fertilised egg implants and develops into a fetus. It provides a nurturing environment for the developing embryo.
• Placenta (iv) - nourishes the growing embryo (c): The placenta is an organ that develops in the uterus during pregnancy. It provides oxygen and nutrients to the growing baby and removes waste products from the baby's blood.
