The genomic characteristics and phylogenetic analyses indicate that P. bursaria is the basal clade of the Paramecium genus. Seine Größe beträgt 90 bis 150 μm. With the exception of the green Paramecium bursaria, which is positively phototactic, other species are indifferent to ordinary light. • Paramecium shows animal characteristics, whereas Euglena shows both animal and plant characteristics. These cilia are in constant motion and help it move with a speed that isfour times its body’s length per second. The green algae uses the waste from the paramecium as food and in turn supplies oxygen for the paramecium to use. Reproduction occurs when the paramecium doubles in size and then divides in two through the process of binary fission. It is the most common ciliates, characterized by the presence of cilia, nuclear dimorphism and unique type of sexual reproduction (conjugation). This protozoan is a member of the group of living beings, known as animal kingdom. A paramecium is a single-celled protist (single-celled microscopic organism) found naturally in most water habitats.

There are at least eight species of Paramecium.Two examples are Paramecium caudatum and Paramecium bursaria. To establish endosymbiosis with alga-free P. bursaria, symbiotic algae must leave the digestive vacuole (DV) to appear in the cytoplasm by budding of the DV membrane.This budding was induced not only by intact algae but also by boiled or fixed algae. Some species form relationships with bacteria. Provided below is the scientific classification of paramecium. General Description of Paramecium. Paramecium was named by John Hill in 1752. As symbionts, zoochlorellae use carbon dioxide and nitrogenous and phosphorous wastes and, in illuminated conditions, provide oxygen and useful nutrients to their hosts. P. bursaria Paramecium vary in length from about 0.05 to 0.32 mm (0.002 to 0.013 inch). However, when the light intensity is suddenly and sharply increased, a negative reaction generally follows. Does Hermione die in Harry Potter and the cursed child? Paramecium bursaria is the most studied model ciliate in endosymbiosis research because of its easiness of cultivating and cloning and it can be identified rather easily from its morphology [10,11].
