Solution

(i) Hibiscus (Rosa sinensis)
(ii) 1 - Corolla (petal) 2 - Stigma 3 - Stamen 4 - Ovary
(iii) Mechanism of pollination in the hibiscus flower:
Hibiscus is a flower with colourful corolla.
Insects get attracted to the nectar and the coloured corolla. Hence, they act as agents of pollination for the hibiscus flower. When insects suck the nectar, pollen grains stick to their legs and are carried to other plants where they germinate.
