Filamentation (or filamentary structure) is often seen in plasmas.It is created because plasma contains free electrons, making it highly electrically conductive — even more than metals, and even in tenuous cosmic plasmas.As charged particles readily move in a plasma, a ring of magnetic field forms around the current that can pinch it into filamentary current strands (ie. Stamens can be connate (fused or joined in the same whorl) as follows: Anther shapes are variously described by terms such as linear, rounded, sagittate, sinuous, or reniform. filament meaning. A flower having only functional stamens and lacking functional carpels is called a staminate flower, or (inaccurately) male. Flower Flowers are the reproductive organs of the flowering plant. Stamen definition, the pollen-bearing organ of a flower, consisting of the filament and the anther. Meaning and Definition of filament. The male part in a flowering plant is the stamen.

Pollen carries the male sex cells of the plant, which are produced on a structure called the stamen or androecium, often known more descriptively as the filament. The filament serves a structural purpose to the reproduction of the plant by extending the anthers and making the pollen more accessible to pollinating animals, such as hummingbirds and honeybees. It may grow a pollen tube and undergoing mitosis to produce two sperm nuclei. Filament Means. After arriving, the pollen grain (an immature microgametophyte) typically completes its development.
