Feeding process in amoeba
WebABSTRACT. Amoeba occasionally feeds on the ciliate Frontonia.In the instances of feeding observed, the Frontonia was not ingested whole but was cut in half by the Amoeba.One half of the Frontonia is engulfed in a food cup of the Amoeba, the pseudopods of the cup producing an annular constriction in the middle region of the ciliate.The pseudopodial … WebPinocytosis is the name given to the process by which the amoeba "imbibes" water from its surroundings. The process is essentially similar to phagocytosis, in which food particles are ingested, but instead, pond water is enclosed in a vesicle or vacuole which becomes part of the cell contents.
