(a) Give one function of each of the following parts in a flower :
- (i)Ovary
- (ii)Stigma
- (iii)Anther (b) Name any three parts of a flower which may fall off after fertilisation.
Answer
Ovary holds ovules and becomes the fruit; stigma receives pollen; anther makes pollen; petals, sepals and stamens may fall off.
(a) (i) Ovary: contains the ovules with the female germ cells, where fertilisation takes place; after fertilisation it develops into the fruit.
(ii) Stigma: receives the pollen grains during pollination.
(iii) Anther: produces the pollen grains, which contain the male germ cells.
(b) Petals, sepals and stamens (the style and the stigma may also fall off).
