What are Archaea? – Unique prokaryotes found in extreme environments | @Anthara_EduConnects

1. Definition
Th Definition
Archaea are single-celled, prokaryotic microorganisms that lack a true nucleus and membrane-bound organelles. They belong to a separate domain of life called Archaea.

2. Cell Structure
Cell wall does not contain peptidoglycan (unlike bacteria).
The cell membrane has unique lipids that provide stability.
Genetic machinery is similar to that of eukaryotes.

3. Key Characteristics
Can survive in extreme conditions (high temperature, salinity, acidity).
Some are also found in moderate environments like oceans and soil
Show diverse metabolic activities.

4. Types of Archaea
Methanogens – produce methane (found in swamps, guts of animals).
Halophiles – live in highly salty environments.
Thermoacidophiles – thrive in hot and acidic conditions.

5. Reproduction
Reproduce asexually by binary fission, budding, or fragmentation.
No formation of spores.

6. Metabolism
Can be autotrophic or heterotrophic.
Some perform chemosynthesis.
Methanogenesis is unique to archaea.

7. Importance
Help in biogeochemical cycles (carbon cycle).
Used in biotechnology and research due to their stability in extreme conditions.
