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.
Thank you... All cells are broadly classified into prokaryotic cells and eukaryotic cells, according to whether their genetic materials are enclosed by a nuclear envelope or not. Prokaryotic cells (pro-primitive, karyon-nucleus): From the morphological point of view, prokaryotic cells are the most primitive cells.They do not contain a definite nucleus. The chromatin bodies remain scattered inside the cytoplasm. Such a type of nucleus without a nuclear membrane is called a nucleoid.ukaryotic cells: These are believed to have been evolved from the prokaryotes. They contain a definite nucleus. The chromatin bodies are enclosed by a nuclear membrane. Eukaryotic cells are larger than the prokaryotes.
