Bacteria

Bacteria are microscopic, single-celled organisms that can be found in various environments, including soil, water, and living organisms. They are characterized by their simple structure and lack of a nucleus. While some bacteria are beneficial and essential for processes like digestion and nutrient cycling, others can be pathogenic and cause diseases. bacteria are classified into different groups based on their shape, staining properties, and metabolic capabilities.
