The anther.
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
Pollen sacs are structures found on the anthers of flowers in which pollen grains are produced and stored. They are typically small, oval-shaped structures that contain numerous pollen grains. Pollen sacs can vary in color, size, and texture depending on the plant species.
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
a flower produce pollen sacs which has pollen grains in it
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.
microsporangium
pollen grains are the powdery pollens in the pollen sacs . Pollen sacs are situated in the anther. For a pistil to develop into a fruit and ovules to mature into seeds, pollen grains must be transfered from anthers to the stigma. This process is called pollination.

Pollen grains have air-sacs to help them float in the air and be carried by wind or insects for pollination. The air-sacs provide buoyancy and allow the pollen grains to be dispersed more effectively to reach other flowers for fertilization.
When bees are collecting pollen, the grains stick to specialized hairs around the knee joint of their hind legs, forming sacs. After an hour of collecting a build up of pollen grains, usually yellowish in color, is quite visible on the hind legs. The fuzzy hairs, stickiness of the pollen and electrostatic electricity contribute to the build up of these sacs.
