How are flowers adapted to wind and insect pollination?

answers

• ​Insect pollination / Entomorphilous flowers are scented to attract insects have stick stigma for pollen grains to stick on. Are brightly coloured to attract insects.
• Have nectarines to secrete nectar; nectar attracts insects
• Have nectar guides to guide the insects to the nectarines
• Stigma/ anthers are located inside the flower / tubular a 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 to be easily seen by the insects/ attract
• Anthers firmly attached to filament for insect to brush against
• Have landing platform to ensure contact with anther and stigma
• Mimiory to attract (male) insects/ flowers mimic female insects which attract
• Anthers firmly attached to filament for insect to brush against
• Have landing platform to ensure contact with anther and stigma
• Mimiory to attract (male) insects/ flowers mimic female insects which attract male insects for mating e.g. orchids. ​
• Anthers/ stigma hang outside the flowers to increase chances of pollination; style/ filament is long to expose stigma/ anthers stigma is hairy/ feathery/ branched  to increase surface are 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  are loosely attached to filaments to  enable them sway easily to release pollen grains;  pollen grains  may have  structures  which  contain  air  to increase buoy any  3 flowers have long stalks holding them  out in the wind
