Unicellular organisms are often considered simple creatures and are far less complex than most multicellular organisms. Examples of unicellular organisms include bacteria (E. coli, Salmonella, etc.), yeast (Candida), and amoebas. Multicellular organisms are made up of more than one cell (the prefix multi means many). Multicellular organisms are often composed of millions or trillions of cells (in the case of animals and humans) and are considered to be more advanced on an evolutionary scale. It is an advantage for an organism to be multicellular rather than unicellular.
A hernia is the protrusion of an organ or piece of tissue from its normally contained space.
