multicellular
Not single-celled life
Multicellular describes organisms composed of many cells working together, as opposed to single-celled life forms like bacteria or amoebas.
All animals, plants, and fungi are multicellular—their cells specialize for different functions: Multicellular organisms develop complex tissues and organs.
The term appears mainly in biological contexts.
