What are the functions of a stamen?
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.
What are the main parts of the stamen?
The stamen is the male reproductive organ of the flower (Fig. 1A). It consists of two parts: the anther and a supporting filament.
What is stamen write the function of its various parts?
Stamen is the male reproductive part of a flower, while pistil is the female reproductive part of a flower. The stamen is surrounded by anther and filament. The anthers produce pollen grains.
What is the function of stamen for Class 7?
Stamen is the male reproductive organ of the plant . The stamen is made of two parts: a filament and an anther. The stalk of stamen is called filament and the swollen top of stamen is called anther. Anther makes the pollen grains and stores them.
What are the parts of gynoecium?
Gynoecium is made up of three parts namely stigma, style, ovary.
What are stamens short answer?
The stamen is a male reproductive organ of a flower. It produces the pollen. The stamen has two parts: anther and stalk. These undergo meiosis, and produce pollen grains, which contain the male gametes (sperm). The pollen grains are actually haploid male gametophytes.
What is the role of stamen in reproduction?
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.
What’s the meaning of stamens?
stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. All the stamens of a flower are collectively called the androecium.
What are the parts of androecium and gynoecium?
The androecium has stamens with anthers that contain the microsporangia. The innermost group of structures in the flower is the gynoecium, or the female reproductive component(s). The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary. A flower may have one or multiple carpels.
What are the two parts of stamen in answer?
The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up.
What stamen means?
Pollen grains are microsporangium that carries male gametes, and stamens are microsporophylls that bear microsporangia. So, Stamens represent microsporophylls. Pollination is the process through which flowering plants reproduce sexually.
