As seen above, bacteria can be rods, spheres, spirals, flagellated, unflagellated or other shapes. b. Oxygen demand According to the environment in which they are found, bacteria are placed in one of 3 groups: anaerobic, aerobic, or facultative aerobic bacteria. Introduction To Biology Aerobic bacteria: These need oxygen in their environment. Their respiration is aerobic (as in plants and animals). Because they lack mitochondria, they can get only a limited amount of energy. Enzymes responsible for respiration are found mainly in mesosomes.
