Answer :

Final answer:

Viruses that specifically infect bacterial cells are known as bacteriophages and they typically infect only certain strains or species of bacteria due to their specific host ranges. Therefore, the correct option is A) True.

Explanation:

A virus that can infect a bacterial cell is called a bacteriophage, often abbreviated to phage. These viruses are indeed known to infect only specific strains or species of bacteria. Viruses, being obligate intracellular parasites, have specific host ranges and typically can only infect particular hosts and specific cell types within those hosts. While viruses are known to infect various types of host cells, including those of animals, plants, fungi, protists, bacteria, and archaea, most viruses are highly specialized and will not have a broad host range. It is also true that viruses cannot replicate on environmental surfaces or in synthetic laboratory media as they require the cellular machinery found within living cells to reproduce.
