Consider the following:1.Bacteria2.Fungi3.VirusWhich of the above can be cultured in artificial/synthetic medium?

1. A

   1 and 2 only

   1 and 2 only. Bacteria and fungi grow on synthetic media. Viruses need living host cells.

2. B

   2 and 3 only

   2 and 3 only. Viruses fail the artificial-medium test.

3. C

   1 and 3 only

   1 and 3 only. Same miss on virus.

4. D

   1, 2 and 3

   All three. Virus cannot be cultured on agar alone.

Summary. Official key is (a) 1 and 2 only. Bacteria and fungi take artificial media. Viruses are obligate intracellular — they are grown in eggs, cell lines or animals, not on a flask of broth alone.
