Name the category of plant pathogens: Very small organisms that multiply in living cells.

The concept being tested is the nature of viruses. Viruses are extremely small infectious particles that cannot carry out metabolism on their own and must enter a living cell to replicate, using the host cell’s machinery. This requirement to multiply inside a host cell is what sets viruses apart from other pathogens. Bacteria are single-celled organisms that can grow and divide independently in appropriate environments, so they don’t fit the description of multiplying solely within living cells. Fungi range from single-celled yeasts to multicellular molds and generally can grow and reproduce outside a host, not restricted to intracellular replication. Nematodes are multicellular organisms and do not multiply inside living cells. So, the description best matches viruses.
