Parts of a Flower Petal Style Stigma Anther Filament Stamen Ovary Ovule Nectary Flower stem Sepal
Flower Part Petal Part Function These are used to attract insects into the flower, they may have guidelines on them and be scented. Is covered in a sticky substance that the pollen grains will stick to. It raises the stigma away from the ovary to decrease the likelihood of pollen contamination. It varies in length. Ovules are produced inside this. Stigma Style Ovary Ovule This will become a seed once fertilisation has taken place. Stamen This is the collective name for the anther and the filament. Flower Stalk Gives support to the flower and elevates the flower for the insects. This is where a sugary solution called nectar is produced. Nectary Sepal These protect the flower whilst the flower is developing from a bud. This is the stalk of the anther. Filament Anther Pollen is produced here.
