Diversity Of Life - Part -5| Kingdom Monera Part -1 | CSIR NET Life sciences

Kingdom Monera is one of the classic biological kingdoms (used in older classification systems). It includes the simplest and most ancient forms of life on Earth. Monera includes prokaryotic organisms, meaning their cells do not have a true nucleus or membrane-bound organelles. Under the three-domain system of taxonomy, introduced by Carl Woese in 1977, which reflects the evolutionary history of life, the organisms found in kingdom Monera have been divided into two domains, Archaea and Bacteria (with Eukarya as the third domain) .Some of the important characteristics of Archaebacteria are given below: Archaebacteria Cell Walls: Their cell walls do not contain peptidoglycan, unlike bacteria. Instead, they have unique molecules like pseudopeptidoglycan. Extreme Environments: Archaebacteria can live in extreme conditions such as hot springs, salty lakes, and deep-sea hydrothermal vents. Diverse Metabolism: They can use a variety of energy sources, including hydrogen gas, carbon dioxide, sulfur, and even sunlight (for photosynthetic species). Methanogens: Some archaea produce methane gas as a byproduct of their metabolism. These are called methanogens and are often found in anaerobic environments like swamps and the guts of ruminant animals. No True Nucleus: Like bacteria, archaebacteria are prokaryotes, meaning they lack a true nucleus. Their genetic material is not enclosed in a nuclear membrane. Different Membrane Lipids: Their cell membranes have lipids that are different from those found in bacteria and eukaryotes. These lipids help them survive extreme conditions.
