The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing

, and is often called the building block of life.[1] Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). Humans contain about 100 trillion (1014) cells.[2] Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope
This clearly states that a virus isnt a living organisim
bacteriophages
bacteria-infecting virus: a virus that infects bacteria and may integrate into the genetic material of its host cell. Bacteriophages are used as vectors in gene cloning and have other biotechnological uses.
