Which of the following reproduces only inside a host cell? A. Bacteria B. Virus C. Protist D. Fungus

Dear student,

 

Bacteria, protists and fungus can regenerate and reproduce by cell division without the requirement of a host body. In contrast, viruses are considered to be between living and nonliving because outside the host acts as nonliving and inside the host, they multiply and thus are living. since they can only reproduce in the host cells. This is because the proteins and components required to build their body structures are not encoded by the viral nucleic acids. Thus they rely on host cells for building factors and can only reproduce by infecting living host cells.
So, the correct answer is option B.
