Unicellular organisms are the organisms which have only on cell as the body eg: Amoeba, This is a unicellular organism which can perform all functions just like a multicellular animal.

It performs respiration without any organs just like a multicelluar animal which has respiratory organs(Gills, lungs etc). and also reproduction, excretion, circulation, etc.

A multicellular animal has many cells(Millions, trillions of cells) these cells are grouped to form tissues which perform a similar function (ie all the cells in a tissue perform similar function) The tissues are organized to form organs (Liver, Pancreas, Muscles etc).

There are many differences between a unicellular organisms and multicellular organisms.
