Nutrition in Simple Animals: Amoeba and paramecium are two very simple unicellular animals. In 1959, ‘Ehret‘ and ‘Powers‘ have revealed with the help of electron microscope that the polygons are defined by a corresponding regular series of cavities which is know as alveoli. The dead bacterial cell is unfit for nutriment for P. aurelia and this is not due to the denaturing of a protein but to the loss of some labile substance. When the cilia are present around, the mouth region of paramecium move, back and forth. Genus of Euglena: The Euglena is an acellular, fresh water organism placed in the order Euglenida, class Phytomastigophora, subphylum Mastigophora, phylum Sarcomastigophora, subkingdom Protozoa. In caudatum, cilia of the posterior end of the body are long and form caudal tuft. It is a common method of reproduction in Paramecium which occurs during favourable condition. process in which an organism takes in food, and obtains and processes the nutrients to be broken down for energy, growth, repair and maintenance Auto-trophic (one feeder) Its size varies between 50 to 300um, depending on the species. Energy for beating is obtained from ATP (Adenosine triphosphate). Usually they live in the water having dead or decaying materials.
