Added a label for the buccal overture, a structure frequently mislabeled as the cytostome on diagrams of Paramecium. For an accurate representation of these structures, see: Ralph Wichterman, The Biology of Paramecium, 2nd Edition, 1986 (fig. 1.3A, on... 19:47, 5 June 2017: 1,142 × 1,007 (149 KB) Deuterostome: Lengthened buccal cavity, for ...
Paramecium (/ ˌ p ær ə ˈ m iː s (i) ə m / PARR-ə-MEE-s(ee-)əm, /-s i ə m /-see-əm, plural "paramecia" only when used as a vernacular name) [2] is a genus of eukaryotic, unicellular ciliates, widespread in freshwater, brackish, and marine environments. Paramecia are often abundant in stagnant basins and ponds.
Paramecium are adaptive to many environments due to the diastole and systole movements of the contractile vacuole, which either let in or expel water from the cytoplasm depending on the environment. The micronucleus and macronucleus together contain all of the genetic information for the organism.

Paramecium caudatum [1] is a species of unicellular protist in the phylum Ciliophora. [2] They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. [3] The cilia are used in locomotion and feeding. [2] The species is very common, and widespread in marine, brackish and freshwater environments. [4] [5]
Three Boar's Head deli meat plants were cited for unsanitary conditions, including insects, mold, and "unidentified slime," according to newly released federal records. The new findings suggest ...
In paramecium, the anal pore is a region of pellicle that is not covered by ridges and cilia, and the area has thin pellicles that allow the vacuoles to be merged into the cell surface to be emptied. In ciliates , the anal cytostomes and cytopyge pore regions are not covered by either ridges or cilia or hard coatings like the other parts of the ...
