Which of the following does not have any enzyme in its cells?

Explanation

The word “virus” is derived from the Latin word “virus”, which literally means poison or sticky liquid. Viruses are acellular, ultramicroscopic organisms that can multiply only inside a living cell. Generally, enzymes are absent in viruses; however, some viruses such as retroviruses contain certain enzymes. Chemically, a virus is a segment of nucleic acid surrounded by a protein coat. Outside the host cell, viruses can neither perform any biological activity nor replicate. Enzymes are also present in lichen, bacteria, and algae.
