Viruses are not classified based on:
Correct answer: C. Cell membrane
- A. Morphology
- B. Host specificity
- C. Cell membrane
- D. Envelope
Explanation
Viruses are not classified based on the presence or absence of a cell membrane because:- Viruses do not have a cell membrane like cellular organisms do. Instead, they have a protein coat called a capsid that surrounds their genetic material.- Some viruses have an envelope, which is a lipid bilayer derived from the host cell membrane, but this is not a universal characteristic among viruses.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
