Explanation: 

Detailed explanation-1: -The male parts of the flower are called the stamens and are made up of the anther at the top and the stalk or filament that supports the anther. The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.

Detailed explanation-2: -A flower that possesses both male and female reproductive parts are called bisexual flowers. The male part is called androecium and the female part is called gynoecium. Hibiscus and lily are two common examples of bisexual flowers.

Detailed explanation-3: -Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.

Detailed explanation-4: -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-5: -Stamens and carpels are the male and female reproductive parts of a flower, respectively. Stamens collectively form a whorl known as androecium. Each stamen consists of two parts; the filament and the anther.
