A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. Prokaryotes include bacteria and archaea. Many eukaryotes are multicellular, but the group includes the protozoa, unicellular algae, and unicellular fungi. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4 billion years ago.

Unicellular organisms are the organism which have only single cell. In such organisms all life process are carried out by single cell.
Eg.- Amoeba , paramaecium etc.
these organism starts life as usual from a single cell zygote . These unicellular organisms have short lifespan wheras multicellular have long lifespan because in these organisms have many cells so they can easily repair old and worn out cell. But unicellular have no such features.
Unicellular organisms are known as single celled organisms.
