WebStructure of Centrioles: Centrioles are minute-sub-microscopic micro tubular sub cylinders with a configuration of nine triplet fibrils and ability to form their own duplicates, astral poles and basal bodies, without having DNA and a membranous covering. They are approximately 0.3-0.5 µm in length and 0.15µm in diameter. WebKey points: Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. showtec white pix https://eyedezine.net
