Answer:
Correct Answer: B
Solution:
Floral parts are specialized leaves-sepals, petals, stamens and carpels.
Sepals are protective and green, petals are coloured and attractive, stamens are pollen bearing structures or microsporophylls while carpels are ovule-bearing megasporophylls.
In Poinsettia, the young leaves are brightly coloured to attract insects for pollination.
