Detailed explanation-1: -The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules.

Detailed explanation-2: -The middle part of the pistil is called style. It is a tube which connects the stigma to ovary. It allows pollen grains to go down to the ovary.

Detailed explanation-3: -Structure of Pistil The pistil consists of a swollen base known as the ovary, which contains the ovule. The swollen base elongates upwards into a tube-like structure known as style. The tip of style is known as the stigma, which acts as a platform for receiving pollen grains.
