clear all

Explanation:

• Contains genetic material: Both viruses (either DNA or RNA) and bacterial cells (DNA) have genetic material.
• Does not have a cell wall: Viruses do not have a cell - wall. Bacterial cells have a cell wall (made of peptidoglycan in most cases).
• Is considered a living thing: Bacterial cells are living organisms as they can carry out metabolic processes, grow, and reproduce on their own (by binary fission). Viruses are not considered living as they cannot carry out metabolic processes independently.
• Contains organelles: Bacterial cells (prokaryotes) have some organelles like ribosomes. Viruses do not have organelles.
• Cannot reproduce without a host cell: Viruses need a host cell (its machinery) to reproduce. Bacterial cells reproduce by binary fission independently.

Answer:

• contains genetic material: both viruses and bacterial cells
• does not have a cell wall: viruses
• is considered a living thing: bacterial cells
• contains organelles: bacterial cells
• cannot reproduce without a host cell: viruses
