The Archaebacteria include three types of bacteria that are found mainly in extreme habitats where little else can live. One group lives in oxygen-free environments and produces methane. This group of Archaebacteria are called Methanogens. They can live in the digestive tract of many animals.

Bacteria cells are typically 0.5–5.0 µm in length. Among the smallest bacteria are members of the genus Mycoplasma, which measure only 0.2-0.3 µm, while a few others are so big that they are visible even to the naked eye. For example, Thiomargarita namibiensisis the largest and longest bacteria with a diameter of 100–300 µm (0.1–0.3 mm).
Based on their shape and arrangement, bacteria can be classified into the following four main types: 1. Cocci: spherical, round or oval-shaped, example – Staphylococcus group 2. Bacilli: rod-like or cylindrical shaped, example – Bacillus group, 3. Spirilla: spiral or coil-shaped, example – Spirillum group 4. Vibrios: curved or comma-shaped, example...
Capsule: Made up of complex polysaccharides, it forms the outermost covering of the bacterial cell. Capsules are an important structural component that keeps the bacterium from drying out, also pro...Cytoplasmic Membrane: It is a semi-permeable membrane composed of lipids and proteins that separates the inside of the cell from its external environment. The cytoplasmic membrane carries out many...Cytoplasm: Present below the cytoplasmic membrane and distributed throughout the cell, it is a gel-like matrix mainly composed of water along with dissolved salts and minerals. Along with some cell...Discover the fascinating world of bacteria and archaea with our free printable science worksheets, designed to help science teachers educate and inspire students in their exploration of these microscopic organisms.
- Domain Bacteria (Kingdom: Eubacteria (True bacteria)) Bacteria are unicellular prokaryotic microscopic organisms. Their unique feature covers the presence of peptidoglycan in the cell wall unlike the Archaea and Eukarya, membrane composed of unbranched fatty acid chains attached to glycerol by ester linkages and their unique rRNA type.
- Domain Archaea (Kingdom: Archaebacteria) These are unicellular prokaryotic organisms that resemble bacteria in their appearance, and hence were fallaciously placed under bacteria before the rise of three domain systems.
- Domain Eukarya. Eukarya is the only domain that represents multicellular, nucleated, and visible organisms with distinct membrane-bound cell organelles although single-celled eukarya also exist.
most bacteria don’t actually affect us! In fact, some bacteria are actually useful to us and other animals and livings things! For example, cows depend on the bacteria that live in their stomach to help them digest the food they eat--if they didn’t have the bacteria, they wouldn’t be able to get the energy they need from their food!
