AP BIOLOGY

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: -The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament. This filament holds the anther in position, making the pollen available for dispersal by wind, insects, or birds.

Detailed explanation-3: -The filament is a long stalk-like structure which supports the anther. The anther is a two-lobed structure which contains microsporangia for the production of pollen grains. Small nectaries are found at the base of stamens which provide food for insect and bird pollinators.

Detailed explanation-4: -Anther and filament are the male parts of a flower. Ovary, stigma, and style are the female parts of a flower.

Detailed explanation-5: -The male reproductive part of the flower is collectively called androecium and consists of an anther and the filament. Pollen grains are present in the anther and they contain the male gametes.
