3.3a: describe the structures of an insect pollinated and a wind pollinated flower and explain how each is adapted for pollination.
in pollination there must be a transfer of pollen from the anther of one plant to the stigma of another.
when pollination occurs between 2 separate plants it is called cross pollination.
pollen is a small structure which contains the male nuclei
the transfer of pollen in an insect pollinated plant is by insects. the flowers must attract insects.
adaptions of plant to attract insects include;
signals. - the colourful petals, scents
value/reward- food (from nectaries produce fructose), pollen as protein
the male part of the flower= stamen composed of anther and filament
the female part of flower= carpel composed of stigma, style, ovary (which contains eggs called ovules)

good notes well done. You can make the video smaller when copying from Youtube. Show you in class.
