Eukaryotic Cell Structure and Reproduction. A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Unicellular organisms can be eukaryotes or prokaryotes, though bacteria are prokaryotes. The prokaryotes are unicellular organisms that do not develop or differ in multicellular forms. Yeasts are unicellular , which are eukaryotes. Yeasts are unicellular , which are eukaryotes. How do single-celled organisms maintain homeostasis? Prokaryotes are unicellular organisms (organisms that consist of one cell) that do not have a cell nucleus that is enclosed in a nuclear membrane, hence the name 'prokaryote' that comes from two Greek words — πρό (pro, 'before') and κάρυον (karyon, 'nucleus').They are some of the simplest beings on Earth.All prokaryotes are divided into two parts: bacteria and archaea. 3.
