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. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther.
The anther is the fertile part of the stamen and usually consists of two distinguishable, contiguous parts, called thecae, joined by an area called the connective, which is also where the anther joins the filament. It is usually formed by two thecae, sometimes it can be constituted by a single theca as in malvaceae and cannaceae or by three in ...
The male stamen is inside the tube-shaped corolla of the disk floret. It has five anthers, five filaments, and produces pollen. The anthers and filaments are readily visible as separate entities in non-Asteraceae species. Here, they are fused together to form a cylinder, or tube, with their pollen on the inside only.
Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. 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.
It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. [1] The top part of the column is formed by the anther, which is covered by an anther cap. This means that the style and stigma of the pistil, with the filaments and one or more anthers, are all united.
[10] (also called pollen vectors): organisms that carry or move the pollen grains from the anther of one flower to the receptive part of the carpel or pistil (stigma) of another. [11] Between 100,000 and 200,000 species of animal act as pollinators of the world's 250,000 species of flowering plant. [12]
Valvular – anthers opening through valves or small flaps; e.g. Berberis. Versatile – anthers pivoting freely on the filament. Pollen – Stamen – Anther – the distal end of the stamen where pollen is produced, normally composed of two parts called anther-sacs and pollen-sacs . Filament – the stalk of a stamen.
Having two valves or hinged parts. Contrast trivalve. blade The lamina or flattened part of a leaf, excluding the stalk or petiole. bloom A fine white or bluish waxy powder occurring on plant parts, usually stems, leaves, and fruits. It is easily removed by rubbing. bole The trunk of a tree, usually the portion below the lowest branch.
