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 ...
The parts are as follows: 1) food vacuoles 2) micronucleus 3) oral groove 4) gullet 5) anal pore 6) contractile vacuole 7) macronucleus 8) cilia. Paramecium move by executing a whiplash movement with the cilia. The cilia also function to help the organism gather food by using them to sweep prey organisms through the oral groove, and into the ...
Paramecium feed on microorganisms such as bacteria, algae, and yeasts. To gather food, the Paramecium makes movements with cilia to sweep prey organisms, along with some water, through the oral groove (vestibulum, or vestibule), and into the cell. The food passes from the cilia-lined oral groove into a narrower structure known as the buccal ...

The spongiome serves several functions in water transport into the contractile vacuole and in localization and docking of the contractile vacuole within the cell. Paramecium and Amoeba possess large contractile vacuoles (average diameter of 13 and 45 μm, respectively), which are relatively comfortable to isolate, manipulate and assay.
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 ]
Paramecium bursaria harbors approximately 700 cells of zoochlorellae (green algae) from the genera Chlorella or Micractinium under its cell cortex, forming endosymbionts. [5] [6] The core principle of these endosymbionts is nutrition, where the host obtains nutrients through phagotrophy by engulfing cells or particles, including Chlorella, which are digested in the digestive vacuole (DV).
