Quick Answer. Multicellular organisms are composed of more than one cell, while unicellular organisms are a single living cell. This difference determines the size and complexity of an organism, as well as the division of labor within it. Each kind of organism has its own set of survival benefits.
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. Historically, the simple single celled organisms have sometimes been referred to as monads, specially the unicellular flagellates. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi.
