Question

Describe the structure of a typical flower. What are the essential organs of a flower?

Accepted Answer

A flower is the reproductive structure found in flowering plants. The typical flower consists of the vegetative part which includes corolla and calyx and reproductive part includes stamen and pistil. The following parts are given below:

1. Stalk- The part by which a flower is attached to the branch is called stalk.

2. Sepals- The small, green coloured, leaf shaped structures found on the outermost part of the flower are called sepals. They are considered to be modified leaves. They protect the flower when they are in the stage of bud and support the petals when in bloom.

3. Petals- Petals are coloured, modified leaves that surround the reproductive parts of flowers. They are brightly coloured or unusually shaped to attract insects for pollination.

4. Stamen- Stamen is the pollen- producing, male reproductive organ of a flower. Stamen usually consists of a long slender stalk, the filament, with the anthers at the tip.

5. Pistil- Pistil is the ovule producing, female reproductive part of a flower. It is the innermost part of a flower. The pistil consists of three parts: stigma, style, ovary.

The stamen, which is the male reproductive part, and pistil, which is the female reproductive part are essential organs in the flower. While sepals and petals are accessory parts of the flower.
