Amitosis is formed from the Greek words a meaning not, mito meaning thread and osis meaning state. The process in which a cell directly produces two daughter cells without any complex medium is called amitosis. Walter Flemming first used the term amitosis in 1882. In 1955 scientist Remak first observed amitosis cell division in red blood cells of chick embryos. Amitosis occurs in cells such as bacteria, yeast, amoeba, nostoc, cartilage of vertebrates, embryo membrane, endosperm of seeds etc.
