Flowers are how plants produce seeds to reproduce. In many cases, the flower contains male and female parts, roughly equivalent to the male and female sexes of animals. 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.n many cases, the flower contains male and female parts, roughly equivalent to the male and female sexes of animals.
