true motility Correct Answer-directed motion of bacteria (energy expenditure by the cell) brownian movement Correct Answer-random back-and-forth jiggling motion due to collisions of water molecules with the cells (cells don't go anywhere)... results from kinetic energy of molecules around the cell flagella Correct Answer-long, whip-like structures that extend beyond the surface of the cell and glycocalyx and propel the cell through its environment. Composed of flagellin serovars Correc...
