All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni - and partially multicellular, like slime moldsand social amoebae such as the genus Dictyostelium.

Multicellular organisms arise in various ways, for example by cell division or by aggregation of many single cells.[2] Colonial organisms are the result of many identical individuals joining together to form a colony. However, it can often be hard to separate colonial protists from true multicellular organisms, because the two concepts are not distinct; colonial protists have been dubbed "pluricellular" rather than "multicellular".[3][4]
