How are flowers adapted to wind and insect pollination? Insect pollinated flowers
(entomophilus)


Answer:

•are scented to attract insects
•have stick stigma for pollen grains to stick on
•are brightly coloured to attract insects
•presence of nectar to attract insects
•have nectar guides to guide insects to the nectarines
•have nectarines to secrete nectar
•stigma/ anthers located inside the
flower/tubal/funnel shaped corolla to increase chances of contact by insects
•sticky/spiny/spiky pollen grains which stick on the body of insects and on
stigma
•large/conspicuous flowers easily seen by/attract insects
•anthers firmly attached to the filament for insects to brush against them
•landing platform to ensure contact with anthers and stigma Wind pollinated flower
(anemophilus)
•anthers/stigma hang outside the flower to increase chances of pollination
•the style/filament is long to expose stigma/anthers
•stigma is hairy/feathery/branched to increase surface area over which pollen grains land/to trap pollen grains
•pollen grains are smooth/dry/light/small to be easily carried by wind
•large amount of pollen grains to increase chances of pollination
•anthers loosely attached to filaments to enable them to sway to release pollen grains
•pollen grains may have structures which contain air to increase buoyancy
•flowers have long stalks holding them out in the wind
