WebParamecium, genus of microscopic, single-celled, and free-living protozoans. Most species can be cultivated easily in the laboratory, making them ideal model organisms, well suited for biological study. … Paramecia cells are characteristically elongated. Historically, based on cell shape, these organisms were divided into two groups: aurelia and bursaria, according to the \"The Biology of Paramecium, 2nd Ed.\" (Springer, 1986). The aurelia morphological type is oblong, or \"cigar\" shaped, with a somewhat tapered … See more Cilia also aid in feeding by pushing food into a rudimentary mouth opening known as the oral groove.
