Detailed explanation-1: -Viruses are not classified as being alive because they don’t have their own machinery for reproducing. They can only take over the machinery of cells, turning them into virus factories. Q. A virus is considered as a living organism and an obligate parasite when inside a host cell.
Detailed explanation-2: -Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don’t reproduce independently but must replicate by invading living cells.
Detailed explanation-3: -Final Answer: Viruses do not infect bacteria, fungi and algae is not the correct statement.
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: -Living things have cells. Viruses do not have cells. They have a protein coat that protects their genetic material (either DNA or RNA). But they do not have a cell membrane or other organelles (for example, ribosomes or mitochondria) that cells have.
