2.PETAL

Petals form a crucial role in a plant's reproductive cycle. This is because they allow plants to pollinate. They do this by using their scent, colour and other evolutionary features to attract the correct type of pollinator.
3.SEPAL

Sepals are small, leaf-shaped, green-coloured and outermost part of the flower. They are the vegetative part of a flower, which functions by protecting the rising buds and by supporting the petals when in bloom. The sepals are considered as the modified leaves.
4.STAMEN

Stamens are the male reproductive organs of flowering plants. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal.
5. OVARY

The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself will mature into a fruit, either dry or fleshy, enclosing the seeds.
