What are viruses, and why are they placed outside the five-kingdom system?
Original Khojo Papers practice question — not from a past board paper.
Answer
Viruses are non-cellular infectious particles consisting of a nucleic acid core surrounded by a protein coat. They are placed outside the system because they have no cellular organisation, cannot metabolise or reproduce on their own, and are inert outside a living host, so they fit none of the five kingdoms.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
They can be crystallised, which no cellular organism can.
