Interesting facts
bacteria are essential to many basic ecosystem processes. Some types of bacteria can break down fallen wood and litter returning nutrients to the soil.
The number of bacteria on earth is estimated to be 5,000,000,000,000,000,000,000,000,000,000.
Bacterial evolution refers to the heritable genetic changes that a bacterium accumulates during its life time, which can arise from adaptations in response to environmental changes or the immune response of the host. Because of their short generation times and large population sizes, bacteria can evolve rapidly.
Bacteria are often referred to as having a 'spherical' shape. Bacteria are categorized based on their shapes into three classes: cocci (spherical-shaped), bacillus (rod-shaped) and spirochetes (spiral-shaped) cells.
