Bacteria | Microschool Dev

Bacteria are single-celled prokaryotic microorganisms that form one of the three domains of life. They are ubiquitous, found in every habitat on Earth, from soil and water to the human gut. While often associated with disease, the vast majority of bacteria are harmless or even beneficial, playing crucial roles in nutrient cycling, decomposition, and symbiotic relationships. Their incredible adaptability and rapid reproduction rates have allowed them to evolve diverse metabolic strategies, making them key players in ecosystems and biotechnology.
