Flower Parts Lables

This is for my Nina,

Flower Parts and Part Function

  • Petal Petals:  are used to attract insects into the flower, they may have guidelines on them and be scented. 
  • Stigma:   Is covered in a sticky substance that the pollen grains will adhere to. 
  • Style:   The style raises the stigma away from the Ovary to decrease the likelihood of pollen contamination. It varies in length.
  • Ovary:   This protects the ovule and once fertilization has taken place it will become the fruit. 
  • Ovule:   The Ovule is like the egg in animals and once fertilization has taken place will become the seed. 
  • Receptacle:   This is the flower's attachment to the stalk and in some cases becomes part of the fruit after fertilization e.g. strawberry. 
  • Flower stalk:   Gives support to the flower and elevates the flower for the insects.
  • Nectary:   This is where a sugary solution called nectar is held to attract insects.
  • Sepal:   Sepals protect the flower whilst the flower is developing from a bud. 
  • Filament:   This is the stalk of the Anther.
  • Anther:   The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilized.
