Archaebacteria Kingdom
Archaebacteria
Description: Archaea are a group of microscopic organisms that are single-celled prokaryotes. They can exist in extreme conditions, such as extremely hot, acidic, or alkaline environments and are not reliant on any one source energy. Some archaebacteria sustain themselves by consuming hydrogen gas or metal ions, however other archaebacteria live inside more complex organisms.
Divergent Event: Aechaebacteria have a long evolutionary line, which makes it difficult for experts to identify exactly when they appeared and evolved from the Eubacteria. Through fossil examination, experts suggest that it occured about 3 billion years age, which is the age of the oldest deposit in which archaebacteris have been found. The lineage of archaebacteria is possibly the most ancient, as they are the simplest of prokaryotes.
Cell Type: Prokaryotic
Cell Structure: Prokaryotic cells have no true nucleus as the DNA is not separated from the rest of the cell, but coiled up in the nucleoid. Prokaryotic cells have a cell membrane, cell wall, one long DNA strand, simple cilia or flagella, and ribosomes.
Body Plan: Archaebacteria are unicellular.
Metabolism: Archaebacteria are both heterotrophic and autotrophic. Autotrophic archaebacteria create organic matter from mineral compounds, using the energy of certain chemical reactions and play a role in the circulation of matter in nature. Heterotrophic archaebacteria use organic compounds as a source of energy and take an active part in the natural recycling of substances.
Reproduction: Archaebacteria reproduce asexually by binary fission, budding, or fragmentation. Most Archaebacteria perform binary division to reproduce, splitting their nuclei into two.
Examples: Ferroglobus placidus, which lives next to hydrothermal vents, is able to endure temperatures of up to 95 degrees Celcius.
Sulfolobus solfataricus, an archaebacterium found in Yellowstone National Park, which lives in areas that have volcanic activity
