Unicellular organisms are organisms that have one cell. They are divided into two quite different types, from different classification kingdoms. 1  The prokaryotes, bacteria and archaea, have cells with no nucleus and a simple cell structure.2  Eukaryotes have a nucleus, and a more complex cell structure.nicellular organisms are organisms that have one cell.

Reproduction based on the number. Unicellular organisms are single celled forms whereas multicellular organisms are made up of many cells. Depending upon the complexity of the body, reproduction in unicellular organisms is different from that of multicellular organisms. 1  Unicellular organisms reproduce by asexual means.2  This asexual mode of reproduction involves single parent to produce their offspring. Amoeba is a simple, unicellular organism which reproduces by transverse binary fission. 2  The division begins with the division of nucleus. 3  Binary fission can also be observed in multicellular animals like sea anemones and planarians. 4  Binary fission observed in Leishmania is longitudinal binary fission.
