Scientific Name:Amoeba proteus
An amoeba feeds by sending out 'bulges' of its cytoplasm, called pseudopodia, to surround a small food particle eg a smaller protozoan or an alga. The food, together with a small drop of the water is taken into the cell to become a food vacuole.
Be on the Lookout
Sometimes amoebas will come together to form a big blob called a slime mold.
The name amoeba is derived from the Greek word ‘amoibe’, which means ‘to change’. Prior to that, amoeba was referred to as Proteus animalcule. Proteus is a Greek god, who could change shape.
contractile vacuole - a cavity within the amoeba that excretes excess water and waste; the waste is brought to the cell membrane and is then eliminated from the amoeba.
cytoplasm (ectoplasm and endoplasm) - a jelly-like material that fills most of the cell; the organelles (like the nucleus) are surrounded by cytoplasm.
food vacuole - a cavity within the amoeba in which food is digested (broken down in order to be absorbed by the amoeba).
