Flower is defined as highly condensed and modified reproductive shoot. The part from where flower arise is called bract. Flower has short or long flower stalk which is called pedicel. The upper part of pedicel is swollen, spherical shaped or conical which is called thalamus / Receptacle.

The important functions of flowers are mentioned below:

• Gametophytes develop in the flowers.
• The flowers can produce diaspores without fertilization.
• After fertilization, the ovary of the flower develops into a fruit containing a seed.
• The most important function of flowers is reproduction. They help in the union of male and female gametes.
• Flowers provide nectar to certain birds and insects, which in turn help in the transfer of pollen from one flower to the other.
• Flowers may promote selfing, i.e., the union of sperms and eggs from the same flower, or cross-fertilization, i.e., the union of sperms and eggs from different flowers.
