Cyanophages have been isolated from

(a) Lyngbya (c) Plectonema

(b) Phormidium (d) All of these

Distinguish between a virion and a viroid. Name the types of microorganisms that harbour viruses. Do these viruses differ from animal and plant viruses? If so, how? Compare the mechanism whereby an animal virus and a bacterial virus attach to and enter a host cell.
