Multicellularity is the characteristic in which the organisms are composed of more than one cell. In contrast to this, the whole body of a unicellular organism consists of a mere one cell. Examples of multicellular and unicellular organisms include animals, plants, fungi and bacteria, protists, etc. respectively. The multicellular organisms evolved by the successive divisions which led to forming an aggregation composed of cells.
Colonial organisms also depict multicellularity. The colonies are formed when the individuals of the same species join together to form a colony. Moreover, the life span of multicellular organisms is longer but due to this, they may face the challenges of not regulating their growth which resultantly form various forms of cancers.
