-bearing structure of the stamen of a flower, usually borne on a slender stalk called the filament. Each anther generally consists of two pollen sacs, which open when the pollen is mature. The method of opening, or dehiscence, is uniform in any single species of plant.



the principal part of the stamen. The anther consists of symmetrical halves, each of which has one or two pollen sacs. The two halves are united by the continuation of the anther filament. The pollen sacs of angiosperms are homologous to the microsporangia of Pteridophyta and gymnosperms; the anther itself is homologous to the synangium. Microspores develop in the pollen sacs; pollen grains form from the sacs. After the opening of the anther, the pollen grains leave through two vertical slits. The grains may fall onto the stigma of the pistil, where development continues.


The pollen-producing structure of a flower.


the terminal part of a stamen consisting usually of two lobes each containing two sacs in which the pollen matures

Finally, they share the anthers basally connate to each other, forming a stellate structure in a top view, and bearing a small central entrance-hole to the internal chamber formed by the filaments, which hides the female organs.
That observation got him and colleagues thinking: "If we could cover wheat heads and anthers with organisms that use choline, could we 'blind' the scab fungus to this cue'?
After that, they never touch the anthers and stigma again," Richardson says.
The 15cm (6in) wide flowers are a rich, velvety purple-red with a glowing boss of golden anthers.
Each flower has three sets of standards, falls, crests (small, upright, ridged structures at the base of each fall), stamens with pollen-bearing anthers that sit under the crest, and stigmas (lip-like structures on the lower side of the crest), where the pollen is deposited.
The combination of pink-flushed buds, opening to flowers of softest apricot splodged with chocolate, and alluring apricot flowers finished with marmalade orange anthers, is almost too much to take in.
Pollination is the transfer of pollen grains from the anthers (the male reproductive organs of flowers) to the stigmas (the female reproductive organs) to start the process of sexual reproduction.
