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.
|Insect Pollinated||Wind Pollinated|
|large, brightly coloured petals - to attract insects||small petals, often brown or dull green - no need to attract insects|
|often sweetly scented - to attract insects||no scent - no need to attract insects|
|usually contain nectar - to attract insects||no nectar - no need to attract insects|
|moderate quantity of pollen - less wastage than with wind pollination||pollen produced in great quantities - because most does not reach another flower|
|pollen often sticky or spiky - to stick to insects||pollen 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 it||stigma hangs outside the flower - to catch the drifting pollen|
|stigma has sticky coating - pollen sticks to it||stigma feathery or net like - to catch the drifting pollen|
