Sheree observed an amoeba feeding by engulfing the prey with its false feet or pseudopods. This process is known as phagocytosis.
The term comes from Greek and means: phagein = to devour, kytos = cell, -osis = process, so it literally means that it refers to a process in which a certain type of a cell (in this case, an amoeba) devours or eats another thing.
