Although generally not visible to the naked eye, organisms composed of prokaryotic cells still dominate the earth. Their collective mass is at least 10 times greater than the mass of all eukaryotes combined. Organisms composed of prokaryotic cells are classified into 2 main groups: archaea and bacteria. Archaea most closely resemble the first primitive cells on our planet.
a prokaryotic cell is a cell that does not have a nucleus or membrance covered organelles. and a a eukaryotic is a is a cell that has a nucleus membrane covered organelles.2 people found this useful. Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.   But, prokaryotic cells do not have membranes around their organelles (inside the cell â¦), whereas eukaryotic cells do.
