Organisms made up of different groups of specialized cells are always?

Organisms made up of different groups of specialized cells are always multicellular. These specialized cells work together to perform various functions, allowing the organism to grow, develop, and maintain homeostasis. Examples of multicellular organisms include plants, animals, and fungi, all of which exhibit complex structures and systems due to their cellular specialization. In contrast, unicellular organisms consist of a single cell that carries out all necessary life processes.
