Flower Adaptations to Pollination

Insect pollinated flowers /entomorphilus flowers;
i. Are scented to attract insects;
ii. Have sticky stigma for pollen grains to stick on;
iii. Are brightly coloured to attract insects;
iv. Presence of nectar to attract insects;
v. Have nectar guides to guides to guide the insects to the nectarines;
vi. Have nectarines to secrete nectar;
vii. Stigma / anthers located inside the flower / tubular or funnel shaped corolla to increase chances of contact by insects;
viii. Sticky / spiny / spiky pollen grains which stick on the body of insect; and on stigma;
ix. Large/ conspicuous flowers to be easily seen by insects / to attract insects;
x. Anthers firmly attached to filaments for insects to brush against them;
xi. Mimicry to attract (male) insects;
xii. Landing platform to ensure contact with anthers and stigma;
Wind pollinated flowers /anemorphilous flowers
i. Anthers / stigma hang outside the flowers to increase chances of pollination;
ii. The filaments / style is long to expose anthers / stigma respectively;
iii. Stigma is hairy / branched / feathery to increase surface area over which pollen grains land / trap pollen grains;
iv. Pollen grains are smooth / dry / light / small to be easily carried by wind;
v. Large amount of pollen grains to increase chances of pollination;
vi. Anthers loosely attached to filaments to enable them sway to release pollen grains;
vii. Pollen grains may have structures which contain air to increase buoyancy;
viii. Flowers have long stalks holding them out in the wind;
