All living organisms are made up of cells. Unicellular organisms consist of a single cell that performs all basic functions. In multicellular organisms, there are millions of specialized cells. Specialized cells in multicellular organisms carry out specific functions efficiently. Different groups of cells are responsible for different specialized functions.
