Azalea 4


Group Members: Lavanya, Rachael, Julie, Anita

Our group investigated the processes of sexual reproduction in Azalea's plants. The Azalea thrives in acidic conditions in almost all areas of Australia, it comes from the Rhododendron family. It grows as a tree with bright pink flowers and doesn't have fruit.

Pollination and Fertilisation:
  • pollen transfered from anther to stigma
  • pollen is trapped in stigma and germinates to produce pollen tube
  • pollen tube contains male gametes
  • the male gametes fuse with female gametes in ovule (Fertilisation)

Pollen is abundant in Azalea because it lacks nectar therefore it compensates with Pollen to attract and reward the insects.
