Insect pollinated flowers and wind pollinated flowers

Wind pollinated flowers are different in structure from insect pollinated ones. You need to be able to explain the main differences. This table will help to make these clear for you.

Table of flower structure

Insect PollinatedWind Pollinated
large, brightly coloured petals - to attract insectssmall petals, often brown or dull green - no need to attract insects
often sweetly scented - to attract insectsno scent - no need to attract insects
usually contain nectar - to attract insectsno nectar - no need to attract insects
moderate quantity of pollen - less wastage than with wind pollinationpollen produced in great quantities - because most does not reach another flower
pollen often sticky or spiky - to stick to insectspollen very light and smooth - so it can be blown in the wind and stops it clumping together
anthers firm and inside flower - to brush against insects anthers loosely attached and dangle out - to release pollen into the wind
stigma inside the flower - so that the insect brushes against itstigma hangs outside the flower - to catch the drifting pollen
stigma has sticky coating - pollen sticks to itstigma feathery or net like - to catch the drifting pollen
