Pistils: Compare the Carpels and Pistils

The pistil is the female part of the flower, which mainly consists of the stigma, style, ovary, and ovule. It is primarily designed for the process of pollination and is further followed by the fertilization process. During the process of pollination, a compatible pollen grain lands on the stigma, and then further it germinates, forming a pollen tube.
The pollen tube starts to grow down to deposit sperm for the process of fertilization with ovules in the ovary. The pistils are a kind of collective sense of the female reproductive system to collect the male gametes from the male reproductive part or androecium.

Structure of Pistil

It is the female reproductive part of the flower, which is located centrally in the flower. It mainly consists of the swollen base, ovary, a stalk or style arising from the ovary, a pollen receptive tip, and the stigma, which is variously shaped and often sticky. The number of pistils in the flower usually varies with the different species of the flower. From one to many leaf-like structures are enrolled to form each pistil, and its main function is to safeguard the ovules.


Functions of Pistil

The importance of the pistil is given below:

  • It is the female reproductive structure of the flower.
  • It helps to receive pollen and in the fertilization process.
  • The pistil is also involved in the process of germination of the pollen grains.
  • It also helps to transfer pollen grains in the process of pollination.
  • It is composed of the stigma, which has a sticky top and it plays a vital role in the germination process of the pollen grains.

Differences Between the Carpels and Pistils



Flowers have a female reproductive structure, which is called carpels.

A pistil is the female organ of a flower that bears seed.

It consists of an ovary, stigma, and style.

It contains a variety of carpels.

Egg cells are produced within these carpels.

In the pistil, Egg cells are not produced

Undergoes fertilization.

No fertilization occurs.

There is a production of seeds.

There is no production of seeds.

Helps with seed dispersal.

Acts as the flower’s reproductive component.

Carpels and styles play an important role in helping to differentiate the number of carpels in a flower.

It serves to distinguish the number of ovaries in a flower from the number of pistils.
