Etymology
Single-celled combines single ('one') and cell, which comes from Latin cella meaning 'small room' because early scientists thought the tiny parts in plants looked like little rooms under a microscope. So a single-celled living thing is 'made of one cell', which is why the word means a creature with only one cell.
