Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
If the anther is cut perpendicular to its axis, it is observed that each anther contains one or two pollen sacs extending along its entire length. [18] [14] After the maturation of the pollen grains, dehiscence or opening of the anther occurs to let the pollen out. The tissue responsible is called endothecium.
An anther and its filament together form a typical (or filantherous) stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae. Each theca contains two microsporangia, also known as pollen sacs. The microsporangia produce the microspores, which for seed plants are known as pollen grains.
anther The pollen-bearing part of a stamen. antheridium in bryophytes, a specialized gametophytic organ that produces the male gametes. antheridiophore In liverworts of the order Marchantiales, a male gametophore, a specialized, stalked structure that bears the antheridia. antherode A sterile anther of a staminode. anthesis 1.
Stamens consist typically of an anther, made up of four pollen sacs arranged in two thecae, connected to a filament, or stalk. [2] The anther contains microsporocytes which become pollen, the male gametophyte, after undergoing meiosis. Although they exhibit the widest variation among floral organs, the androecium is usually confined just to one ...
The innermost spheres are the terrestrial spheres, while the outer are made of aether and contain the celestial bodies. In Plato 's Timaeus (58d) speaking about air, Plato mentions that "there is the most translucent kind which is called by the name of aether (αἰθήρ)" [ 9 ] but otherwise he adopted the classical system of four elements.
