What is archaebacteria nutrition?

Answer 1

Archaebacteria are microscopic organisms with diameters ranging from 0.0002-0.0004 . The volume of their cells is only around one-thousandth that of a typical eukaryotic cell. Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, liposomes, Golgi complexes, or chloroplasts. The cells contain a thick cytoplasm that contains all of the molecules and compounds of metabolism and nutrition. Archaebacteria have a cell wall that contains no peptidoglycan. This rigid cell wall supports the cell, allowing an archaebacterium to maintain its shape, and protecting the cell from bursting when in a hypotonic environment. Because these organisms have no nucleus, the genetic material floats freely in the cytoplasm. The DNA consists of a single circular molecule. This molecule is tightly wound and compact, and if stretched out would be more than 1,000 times longer than the actual cell. Little or no protein is associated with the DNA. Plasmids may be present in the archaebacterial cell.

Answer 2

Archaebacteria obtain nutrition through a variety of methods, including photosynthesis, chemosynthesis, and heterotrophy. They can utilize organic compounds, inorganic compounds, or light as energy sources for metabolism. Some archaebacteria are extremophiles and thrive in harsh environments such as high temperatures, high salinity, or acidic conditions.
