P. cadatum is a microscopic, unicellular protozoan. The alga provides the Paramecium food and the Paramecium provides the alga a home and transportation. Paramecium bursaria is one of only two species in the genus Paramecium that harbor algal endosymbionts [39, 40]. One of the remarkable and poorly understood pecularities of this system is the steady state in the number of algae per protozoan cell. Possession of cilia is the only common characteristic. Paramecium caudatum is 180-300 um long. We performed an environmental study of viruses infecting the symbiotic single-celled algae of Paramecium bursaria (Paramecium bursaria Chlorella virus, PBCV) in Lake Biwa, the largest lake in Japan. Contact your company to license this image. Its size ranges from 170 to 290um or up to 300 to 350um. "Paramecium bursaria, ciliated protozoans measuring about 150 microns in length, swimming about in pond water. (c) When grown together, P. caudatum and P. bursaria coexist, although at lower densities than when alone. Figure 8.3 Competition in Paramecium. ABSTRACT. One of the remarkable and poorly understood pecularities of this system is the steady state in the number of algae per protozoan cell. This Paramecium species is unique in that it is the only one that forms a symbiotic relationship with zoochlorella, a green alga. Paramecium is a slipper-shaped, unicellular protozoan, with a size ranging from 50-350 µm (micrometer). Paramecium multimicronucleatum is 200-330 um long. Structure of Paramecium Caudatum: (i) Size and Shape of Paramecium Caudatum: Paramecium caudatum (Fig. Based on a phylogenetic tree constructed from Paramecium 18S rRNA sequences with T. thermophila as outgroup, P. bursaria is the most diverged species since the most common Paramecium ancestor , which may explain why P.
