Quizplus · Accepted Answer

Viruses are very small infectious agents that are obligate intracellular parasites, meaning they can only replicate by invading and taking over the machinery of living host cells. Yeast and fungus are types of microorganisms, but they do not solely rely on invading other cells for their survival. Pathogens are disease-causing agents, which can include viruses, but also other types of microorganisms such as bacteria and fungi.
