Multicellularity. On the face of it, the concept seems simple and unambiguous: some organisms package everything needed for metabolism, behavior, locomotion and reproduction into a single cell, whereas others contain multiple cells, commonly with varying functions.

Accordingly, biologists commonly preface “multicellularity” with adjectives that acknowledge various axes of diversity.
