The question of whether paramecia exhibit learning has been the object of a great deal of experimentation, yielding equivocal results. However, a study published in 2006 seems to show that Paramecium caudatum may be trained, through the application of a 6.5 volt electric current, to discriminate between brightness levels.


The fine chromatin threads and granules are uniformly distributed throughout the cell and control reproduction of the cell. The number in a cell varies from species to species. There is no nucleolus present in caudatum. 6. Vacuole. Paramecium consists of two types of vacuoles: contractile vacuole and food vacuole.


Paramecium caudatum is a species of unicellular organisms belonging to the genus Paramecium of the phylum Ciliophora. They can reach 0.25mm in length and are covered with minute hair-like organelles called cilia. The cilia are used in locomotion and feeding. Appearance and physical characteristics


Paramecium are members of the Kingdom Protista, and some of the first organisms a biology student encounters in the laboratory. This lesson will describe Paramecium in nature and explain why they ...


Paramecium, 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. Paramecium vary in length from about 0.05 to 0.32 mm (0.002 to 0.013 inch). Their basic shape is an elongated oval with rounded or pointed ends, such as in P. caudatum.


Paramecium is a type of unicellular ciliates that are members of protista. These protists live in freshwater and constantly take in water by osmosis from outside.


It is claimed that Paramecium Caudatum shows a choice in the selection of its food, but there seems to be no basis for this though it engulfs only certain types of bacteria; available data suggest that 2 to 5 million individuals of Bacillus coli are devoured by a single Paramecium in 24 hours.


What Is a Paramecium? ... Paramecia are single-celled protists that are naturally found in aquatic habitats. They are typically oblong or slipper-shaped and are covered with short hairy structures ...


What type of protist is a paramecium? ... No. A paramecium is a protist which contains a nucleus and therefore is classified to be a eukaryote. If it did not have a nucleus, then it would be ...
