Related to anther: anther culture


minute grains, usually yellow in color but occasionally white, brown, red, or purple, borne in the anther sac at the tip of the slender filament of the stamen of a flowering plant or in the male cone of a conifer.

-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
