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.
The other kingdom, Monera (bacteria & cyanobacteria), consists of prokaryotic cells. Prokaryotic cells, as their name implies, have no true nucleus. They have genetic material (DNA) but it is in a nucleoid region. The eukaryotes have their DNA in a nucleus that is enclosed by a membranous nuclear envelope.The nucleus of the eukaryotes is surrounded in the cell by the cytoplasm. The organelles are located in the cytoplasm. Many of the organelles that are found in eukaryotes are not found in prokaryotes.he other kingdom, Monera (bacteria & cyanobacteria), consists of prokaryotic cells.
