Parts Of A Flower

Flower serves a significant function in plants. As the reproductive part, it ensures the continuance of a species of plant by the process called reproduction. Flowers are not only a part of reproduction but also a source of food for other living creatures. It is a rich source of nectar.

Flowers can either be complete or incomplete. Complete flower consists of:

  • Petals: This is the brightly colored part which attracts bees, insects, and birds. Colour of petals varies from plant to plant; some are bright while some are pale colored. Thus, petals help us to differentiate one flower from another.
  • Sepals: Sepal is the green colored part beneath the petals to protect rising budsSome flowers have fused petals-sepals but some have separated petals-sepals.
  • StamenThis is the male reproductive organ and consists of two parts namely: anther and filament which are usually yellow. Anther is a sac that produces and stores pollen whereas filament supports the anther.
  • Pistil: This is the innermost part of the flowers. The female reproductive organ of a flower comprises of three parts – stigma, style, and ovary which are collectively known as pistil. Stigma is the top most part; style is the long tube which connects stigma to the ovary. The ovary has lots of ovules. It is the part of the plant where the seed formation takes place.
