Document Summary
Shape: coccus: spherical (cocci, bacillus: straight rod (bacilli, vibrio: curved rod (vibrios, spirillum: spiral (spirilla, pleiomorphic: cells with variable shapes, some are rod shaped, spherical , hypae: some bacteria have complex structures with branching, mycelia: 3d versions of hypae that can extend above, below, through the substrate, terichomes, shape is dependent on the organization of the cell wall and the semi rigid structure surrounding the cell, shape can change based on the environment and stressors, some cells either separate or stay connected after they divide, pleiomorphic: cells with variable shapes, some are rod shaped, spherical , hypae: some bacteria have complex structures with branching, mycelia: 3d versions of hypae that can extend above, below, through the substrate (tufts of hyphae, terichomes: smooth, unbranched chains with a polysaccharide sheath coat. Some bacteria have been found beyond the range: thomargarita namibiensis: 700um in diameter, spherical, epulipiscium fishelsoni: 600um, cigar shaped, some mycoplasma cells are up to.
