-Flowers of wind pollinated plants are small; with no bracts, sepals or petals; if present the
petals are small,inconspicuous; often white or green in colour; while insect pollinated flowers
are large; often with brightly coloured petals, bracts or inflorescence; to attract insects.
-Flowers of wind pollinated plants have no nectaries; and no scent; while flowers of insect
pollinated plants are scented; and produce nectar;
-In wind pollinated flowers, the anthers are large; and loosely attached on a flexible filament;
to allow pollen grains to be readily released when wind blows on the anthers; while anthers of
insect pollinated flowers are usually small; and firmly attached on the filaments; this ensures
that the insect rub against the anther; as they crawl into the flower collecting pollen grains
onto their bodies;
-In wind pollinated flowers, the stigmas are feathery; widely spread; this acts as nets to catch
pollen as it floats through the air; while in insect pollinated flowers the stigmas are small;
smooth; and sticky; and are also enclosed; this feature ensures that pollen grains from the body
of an insect stick onto it;
-In wind pollinated flowers, the flowers are simple with no particular shape; while some
flowers that are insect pollinated have petals with grooves or dark lines; leading from the petal
boarder to the nectaries; some have tubular or funnel-shaped corolla; and landing platforms;
to guide the insect to the source of the nectar for their food;
-Flowers of wind pollinated plants are either on long stalks above the leaves; or develop from
flower buds that open before the leaf buds; to increase the flower exposure to air currents;
while flowers of insect pollinated plants are on short stalks; often enclosed by the corolla;
