Bacteria multiply by simple cell division (binary fission) as often as once every 20 minutes if they have enough nutrients and a suitable temperature. Example websites containing suitable images, including electron microscopy, include bbc gcse bitesize [additional resource 1] and the association of the british pharmaceutical industry’s web resources for schools [ar 2].
