HELP INDEX NEXT UP PREVIOUS FEEDBACK ATG Amoeba
Ameoba An amoeba is a little blob of living jelly (protoplasm) that creeps around by putting out pseudopodia (false feet) and flowing into them. It also uses pseudopodia to engulf bits of food which are then digested by enzymes inside the cell. A small bubble (contractile vacuole) in the cytoplasm is able to squeeze out excess water, from species like Amoeba proteus which lives in fresh water ponds. Other Amoebae live as parasites inside animals and may cause disease in man, such as amoebic dysentery caused by Entamoeba histolytica. If an Amoeba's puddle dries up, it can form a cyst membrane around itself and wait for conditions to improve before it emerges again. [CH] {EN}
