BOTANY

Detailed explanation-1: -As a plant’s reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.

Detailed explanation-2: -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-3: -Stamens: Male Reproductive Organs A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.

Detailed explanation-4: -Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells).

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.
