Perfect flowers have both male and female parts. the male part is called the and the female part is called the pistil, stamen stamen, pistil petal, stem bulb, corm

The male part is called the stamen and the female part is called the pistil. The stamen and pistil are both comprised of various structures.
The stamen has two parts: anthers and filaments. The anthers carry the pollen. These are generally yellow in color. Anthers are held up by a thread-like part called a filament.
The pistil has three parts: stigma, style, and ovary. The stigma is the sticky surface at the top of the pistil; it traps and holds the pollen. The style is the tube-like structure that holds up the stigma. The style leads down to the ovary that contains the ovules.
