Organisms like the amoeba, Paramecium are single-celled organisms, they are the oldest forms of life, they existed about 3.8 million years ago.

Prokaryotic unicellular organisms are protists and some fungi. Some of these unicellular prokaryotes live in colonies. They live together and all the cells of the colony is the same. All the process of life is carried out in each cell in order for the cell to survive. Simplest multicellular organisms are made of cells that dependent on each other for their survival.
