Question

Cell theory does not apply to

• A. Fungus
• B. Algae
• C. Virus
• D. Bacteria

Answer 1

Answer:

C. Virus

• The cell theory is a fundamental principle in biology that describes the basic structural and functional unit of all living organisms as the cell.

• It states that: All living organisms are composed of cells.

• The cell is the basic unit of structure and organization in organisms.

• Cells arise from pre-existing cells through cell division.

• While the cell theory applies to most living organisms, including plants, animals, fungi, and bacteria, it does not apply to viruses.

• Viruses are considered non-living entities and are not made up of cells.

• Instead, viruses comprise genetic material (DNA or RNA) surrounded by a protein coat called a capsid.

• They cannot carry out vital life processes on their own and require a host cell to replicate and reproduce.
