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.
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.
Detailed explanation-3: -Since viruses are not made of cells, and do not use cells in any of their processes, they are not related to the cell theory. A virus is nothing more than a protein coat surrounding a piece of DNA or RNA.
Detailed explanation-4: -Viruses are smaller than the bacteria. Viruses consists of a genetic material (DNA or RNA) as well as a protein coat. Viruses require the host cell to reproduce. They are inactive outside the host cell.
