Plants grow all around us. They are seen around our homes, schools, on the roadsides and fields. The majority of the plants that we see around us, bear flowers and reproduce by seeds. Hence, they are called flowering plants. These plants show great diversity in shape, size, habitat and structure. These plants are reproduced from their seeds. The parts of a flowering plant is given below:

  1. Calyx: It is the outermost whorl. Each member of the whorl is called sepal. They are mostly green in color. Calyx protects the flower when it is still a bud and helps in the photosynthesis process.
  2. Corolla: It is the next inner whorl of the flower. Each member of this whorl is called petal. Corolla has bright colors. In some flower, corolla has a kind of glands which secrete sweet juice. Rose flower has the sweet smell. Corolla attracts insects that help in pollination.
  3. Androecium: It is the third inner whorl of the flower, it is male reproductive whorl. Each member of this whorl is called stamen. Each stamen has upper lobe like anther and slender stalk called filament. Anther possesses numerous pollen grains which are male gametes. The anther has lobed sac which contains a mass of powder or dust grains called pollen grains. Each pollen grain has two sex cells which take part in reproduction.
  4. Gynoecium: This is the fourth inner whorl and is the female part of the flower. It is the single tube like swollen at its base and is made up of two carpels (female reproductive organs) fused together. It consists of 3 parts- stigma, style, and ovary. The short neck like part is called the style and longer wider lowermost part is called the ovary. The ovary has two chambers, each containing a number of ovules, the female reproductive unit.Each ovule has a special cell called female sex cell (egg cell or ovum) which takes part in reproduction.

Flower containing calyx, corolla, androecium and gynoecium is called complete and those lacking any one or more such part is called incomplete flower.
