Bacteria Vs Virus

Bacteria are single-celled microorganisms that belong to the domain Bacteria. They are prokaryotic organisms, meaning they lack a defined nucleus and membrane-bound organelles. Bacteria can be found in various environments, from soil and water to the human body, where they can play beneficial roles, such as aiding in digestion, or harmful roles, causing diseases. They reproduce asexually through binary fission and can adapt quickly to changing environments, which contributes to their resilience and diversity.

Viruses are microscopic infectious agents that require a living host cell to replicate and propagate. Unlike bacteria, viruses are not considered living organisms because they cannot carry out metabolic processes independently and lack cellular structures. Composed of genetic material (either DNA or RNA) encased in a protein coat, viruses invade host cells and hijack their machinery to produce new viral particles. They are responsible for a wide range of diseases in humans, animals, and plants, and their study is crucial in fields like virology and medicine.
