-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.

Anther

 

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.

anther

that part of the STAMEN of a flower that produces the male GAMETES and that is located at the end of a flexible stalk (the filament). Each anther usually has four ‘pollen sacs’ in which POLLEN GRAINS (HAPLOID) develop by a process of MEIOSIS. The pollen-grain nucleus divides into generative and tube nuclei, representing a truncated version of the GAMETOPHYTE generation found more clearly in lower plants.
