Quick Answer. Multicellular organisms are composed of more than one cell, while unicellular organisms are a single living cell. This difference determines the size and complexity of an organism, as well as the division of labor within it. Each kind of organism has its own set of survival benefits.
The biggest similarity between them is that they both contain cell. A unicellular organism only has one cell, a multicellular organism has many cells. Multicellular organisms have specialized cells to carry out different jobs (ie.humans have cardiac muscle cells in the heart, and nervous cells in the brain).est Answer: unicellular (bacteria and some eukaryotes) and multicellular organisms (like us) both have the basic unit of life, the cell.
