Bacteria

Bacteria are primitive cells that have no nuclear membrane or organised intracellular organelles. They can be observed when magnified 1000 times. Bacteria have large surface areas compared to their volume, allowing nutrients to enter quickly. This explains the metabolism and rapid growth of bacteria: some bacteria undergo cellular division every 20 minutes!
