Amoeba

Sunday, August 12, 2012

An amoeba is a genus of protozoan (a one-celled microscopic organism), which consists of a mass of protoplasm, constantly changing in shape as it moves about and engulfs organic debris, cells or bacteria particles. They live in stagnant water in pools and ponds, but also as parasites in the blood and organs of the human body, causing diseases that are sometimes fatal. Most amoebas have one nucleus and reproduce asexually by cellular division.
