Prokaryotic cell bacteria
WebProkaryotes (domains Archaea and Bacteria) are single-celled organisms lacking a nucleus. They have a single piece of circular DNA in the nucleoid area of the cell. Most prokaryotes have a cell wall that lies outside the boundary of the plasma membrane. Some prokaryotes may have additional structures such as a capsule, flagella, and pili. WebMar 9, 2016 · Prokaryotic cells are tiny. They are about 10% as wide as the eukaryotic cells of plants, animals or fungi. The diameter of a prokaryotic cell is usually between 1-10 μm, whereas a typical eukaryotic cell is between 10-100 μm. The smallest bacteria, called mycoplasmas, can be as little as 0.1 μm in diameter.
