Archaea are organisms that can survive in extreme hot or cold climates.
They have both the features of prokaryotes and eukaryotes.
They belong to the kingdom Monera and are classified as bacteria as they resemble bacteria when observed under a microscope.
Importance of Archaea:
Archaea contribute a lot to the functioning of the ecosystem.
They perform various functions involved in nutrient cycling, stress response, and phytohormone biosynthesis and by interacting with both bacteria and their hosts.
They are also used for the microbiome-based treatment of plants in agriculture.
