Biology - Multicellular organisms

Multicellular organisms

Organisms that are composed of many cells are multicellular. They normally
possess many types of cells each carrying out different functions. [1]

Often multicellular [2] organisms have groups of cells that act together
to perform a specific function. These groups of cells may be described as
tissues, organs or systems depending on how complex they are.
