Detailed explanation-1: -Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
Detailed explanation-2: -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. Living things reproduce.
Detailed explanation-3: -Viruses are not cells: they are not capable of self-replication and are not considered “alive”. Viruses do not have the ability to replicate their own genes, to synthesise all their proteins or to replicate on their own; thus, they need to parasitise the cells of other life-forms to do so.
Detailed explanation-4: -Viruses are non-cellular organisms, but replicate themselves once they infect the host cell.
