WebThe bacteria are unicellular, achlorophyllous prokaryotic micro-organisms leading either saprophytic or parasitic mode of life. An average bacterial cell may measure 1.25 μ in diameter. The smallest among the known bacteria is dialister pneumosintes (0.15 to 0.3 μ in length) and the largest bacterium is spirillum volutans (13 to 15 μ in length).
