Name: Kingdom Monera
Type of organism: Bacteria
Numbers of species: We cannot begin to estimate
Where they are found: Everywhere - all imaginable habitats
Description: Bacteria are single celled organisms. Their cells have no nucleus. It is this characteristic that makes them different from any other form of life. They can be rod shaped, spiral shaped or round, with hairs (cilia) or tails (flagella) that let them move around. They reproduce by dividing - populations of bacteria can grow very quickly.
Need to know: Bacteria can live everywhere - deep in the ocean in complete darkness, in acid pools, in alkali lakes and even deep within the Earth's crust where no other life exists.
