WebCells can acquire specified function and carry out various tasks within the cell such as replication, DNA repair, protein synthesis, and motility. Cells are capable of specialization and mobility within the cell. Most cells are measured in micrometers due to their small size. WebAll prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface. Flagella and some pili are used for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange.

WebCell motility is the capacity of cells to translocate onto a solid substratum. This behavior is often a hallmark of fibroblastic cells. In epithelial cells, cell motility occurs after the dissociation of a cell from its neighboring cell (s) and after the modification of its position relative to other cells or a solid substrate. Many bacteria and other microorganisms, and multicellular organisms are motile; some mechanisms of fluid flow in multicellular organs and tissue are also considered instances of motility, as with gastrointestinal motility. Motile marine animals are commonly called free-swimming, and motile non-parasitic … See more Motility is the ability of an organism to move independently, using metabolic energy.
