Detailed explanation-1: -Virus-a small nonliving particle that invades and then multiplies inside a living cell. Biologists consider viruses to be nonliving because viruses are not cells. Viruses do not use energy to grow or respond to their surroundings. Viruses can multiply. However they do it differently than other organisms.

Detailed explanation-2: -Viruses are tiny infectious agents that rely on living cells to multiply. They may use an animal, plant, or bacteria host to survive and reproduce.

Detailed explanation-3: -Viruses reproduce inside a living organism. They can develop only inside the cells of the host organisms (which may be an animal, plant or bacterium).

Detailed explanation-4: -Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

Detailed explanation-5: -Virus: Tiny, nonliving particle that contains DNA but lacks other characteristics of living cells. Virion: Individual virus particle. Capsid: The protein coat that encloses the virus’s genetic material. Latency: The dormant state of a virus.
