There's a biological and topological difference between a multinucleate cell (coenocyte) and an organism made up of distinct cells. > if you count this as a single cell, then presumably you'll count a muscle fibre, which is also many nuclei inside a single cell membrane, in which case there are larger single cells inside your own body: Certainly. Human muscle fibres and nerve axons are single-celled, but they aren't organisms.
