Detailed explanation-1: -Bacteria grow in a wide variety of habitats and conditions. While pathogenic bacteria are notorious for such diseases as cholera, tuberculosis, and gonorrhea, such disease-causing species are a comparatively tiny fraction of the bacteria as a whole.

Detailed explanation-2: -The bacteria Deinococcus radiodurans can live in extreme sircumstances. The most extreme extremophile that is known at the moment is the Deinococcus radiodurans. This microbe can survive extreme cold, drought, thin air and acid.

Detailed explanation-3: -A thermophile is an organism-a type of extremophile-that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). Many thermophiles are archaea, though they can be bacteria or fungi. Thermophilic eubacteria are suggested to have been among the earliest bacteria.

Detailed explanation-4: -Most bacteria are 0.2m (micron) in diameter and 2−8m (micron) in length. Bacterial cells are about one-tenth the size of eukaryotic cells.
