Draw a neat diagram showing fertilisation in a flower and label (a) Pollen tube, (b) Male germ cell and (c) Female germ cell, on it. Explain the process of fertilisation in a flower. What happens to the (i) ovary and(ii) ovule after fertilisation?
The pollen tube is a tube that carries the male gamete cells from the pollen grain (or from the stigma of flowering plants) towards the ovules located at the base of the pistil for the process of fertilization.
After fertilization,
(i) the ovary of the flower transforms into fruit, and
(ii) the ovules of the flower develop into seeds.
