Morphology

unicellular = cellular (transparent) = uni + cell + ular

The adjective 'cellular' means 'relating to cells', and adding the prefix 'uni-' ('one') yields the clear meaning 'consisting of one cell'.

Etymology

The word unicellular comes from the parts uni- 'one', like in unicycle, and cell 'a tiny living unit'. So a unicellular organism is a living thing made of just one cell.
