The word 'one-celled' clearly indicates an organism consisting of a single cell, directly derived from 'one' + 'cell'.

Etymology

One-celled comes from the parts one and cell, and cell originally meant a 'small room', like a prison cell. So one-celled means a living thing made of a single tiny unit of life, not many cells.
