Is a archaebacteria a Autotroph or Heterotroph?
Archaea can be both autotrophic and heterotrophic. Archaea are very metabolically diverse. Some species of archaea are autotrophic.
How do eubacteria eat?
Nutrition. A great many of the most familiar eubacteria are heterotrophs, meaning they must take food in from outside sources. Of the heterotrophs, the majority are saprophytes, which consume dead material, or parasites, which live on or within another organism at the host’s expense.
What are three Archaebacteria examples?
Examples of archaebacteria include halophiles (microorganisms that may inhabit extremely salty environments), methanogens (microorganisms that produce methane), and thermophiles (microorganisms that can thrive extremely hot environments).
Are archaebacteria motile?
Archaea use a unique structure for swimming motility which is not hoomologous to bacterial flagella, but instead resembles type IV pili. But in contrast to type IV pili, motion is not achieved by elongation and disassembly of the filament, but by rotation.
Are archaebacteria terrestrial or aquatic?
archaea summary The archaea may be aquatic or terrestrial microorganisms. They exhibit a diversity of shapes, including spherical, rodlike, and spiral forms. In addition, archaea can survive in various extreme conditions, including very hot or salty environments.
What do archaebacteria make their own food?
They can be chemotrophs, which means they make their own food from chemicals around them. If their own food, archaebacteria can eat hydrogen gas, carbon dioxide, and sulfur. Archaebacteria can be eaten by fungi and other bacteria.
Are archaebacteria heterotrophic or autotrophic?
Some Archaebacteria are heterotrophic (get food from another source) and some are autotrophic (make their own food). They can be chemotrophs, which means they make their own food from chemicals around them.
What is the difference between archaebacteria and cocci?
Cocci bacteria are spheres and occur in strains, bacilli bacteria are rod shaped, and spirilla bacteria are spiral shaped. Archaebacteria have no symmetry. Some Archaebacteria are heterotrophic (get food from another source) and some are autotrophic (make their own food).
How do archaebacteria reproduce asexually?
Archaebacteria reproduce asexually through binary fission. Binary fission is where the circular DNA is copied and the cell divide with each cell having an identical copy of DNA. Archaebacteria have an adaption where there can undergo conjugation.
