A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther.
30 gru 2023 · The stamen is the male reproductive organ of the lily flower. It consists of two main parts: the filament and the anther. The filament is a thin stalk that supports the anther, which contains the pollen. The anther releases pollen grains, which are essential for fertilization.
11 cze 2004 · Stamens are the male reproductive organs of flowering plants. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal.
Anther, in flowering plants, the part of a stamen that produces and contains pollen. Each anther is generally borne at the tip of a long slender stalk known as a filament and consists of two lobes that each house a pair of pollen sacs (microsporangia) that produce pollen for pollination.
Each stamen has a long filament holding up pollen sacs called anthers. Inside the androecium is the gynoecium (house of woman), which is composed of carpels. Each carpel has an ovary at the base where ovules are housed. The style emerges from the ovary and is topped by the stigma. Pollen grains land on the stigma and must grow a tube down the ...
1 maj 1987 · Abstract. The growth of the anther filaments in the Lilium bud is essentially exponential after a length of 5 mm is reached, when the cell division rate declines and growth is by cell extension, particularly of cells in the central part of the filament.
A stamen is made up of two parts: anther and filament. The anther produces pollen. The stalk to which the anther is attached is called the filament.
