supports flower in suitable position for pollination
what does sepal do
enclose flower when in the bud
petals
usually bright colours to attract insects that help in pollination.
what does the filament do

stamen is made up of the
anther and filament
what is the carpel made up of
ovary, stigma and style
what does the stigma recieve during pollination
pollen
what does the ovary contain
ovules
what do ovules contain
female egg cells
anther
contains developing pollen grains and opens when pollen is mature
wind seed dispersal
seeds or fruits can float on the breeze or flutter to ground
need to be light weight and have hair or wings so wind can carry them off.
animal seed dispersal
animals eat seeds and then poo them out.
they eat a fruit and the pulpy part of it is digested but the seeds are excreted
water seed dispersal
called hydrocolloid
seeds of plants that grow or are planted near water are usually dispersed by it. they have adaptations to swim in water (light/boyoant)
