Function of female structures in flower

[Carpel]

A

Stigma: Sricky top, receptive surface for pollen
Style: Stalk of Carpel
Ovary: Contains ovule. Matured to become fruit
Sepal: Leaf like structure. Protects flower bed

22

Functions of all organs

A

Roots: Absorb H2O. Anchor plant
Stem: Support leaves + flowers. Transport H2O + sugar. Store food
Leaves: Photosynthesis
Flowers: Reproductive organs. Produce seeds
