Bacteria 💡 , fungi 💡 , and viruses 💡 are distinct types of microorganisms with unique characteristics.
: Bacteria are single-celled organisms that can exist in various environments. They have a cell wall and a simple internal structure. Bacteria can be beneficial or harmful to humans. Some bacteria aid in digestion and produce vitamins, while others can cause infections and diseases. Antibiotics are commonly used to treat bacterial infections.
:Unlike bacteria, fungi are eukaryotic, meaning their cells have a nucleus and membrane-bound organelles. They obtain nutrients through absorption and are often found in moist environments. Some fungi are beneficial, such as those used in food production, while others can cause infections like athlete's foot or fungal pneumonia.
: Viruses are tiny infectious agents that are smaller and simpler than bacteria. They consist of genetic material (DNA or RNA) surrounded by a protein coat. Viruses require a host cell to reproduce and cause infections in humans, animals, and plants. Common viral infections include the flu, common cold, and COVID-19. ❕ Antiviral medications can sometimes be used to treat viral infections, but prevention through vaccines is often the best approach.
