Sepals, petals, stamens and carpel
Explanation:
These floral structures which are attached to the receptacle in whorls include the following:
- Sepals which protect the inner parts of the flower especially in the early stages of development.
- petals are brightly coloured, large and conspicuous especially in insect-pollinated flowers. If petals are fused, the corolla is said to be gamopetalous.
- Stamens constitute the androecium, which is the male part of the flower. Stamens are made up of filaments and anthers which produce pollen grains.
- Carpel form the pistil or gynoecium which is the female part of the flower. A carpel is made up of stigma, style and ovary.
