  2. Fungi

  3. Animals

  4. Cork

Show answer
Correct Option: D
Explanation:

Robert cook first discovered the cells in a cork. He saw small spaces under a microscope and called them cells meaning "little rooms".

bio-chemistry taxonomy of angiosperms cell as structural and functional unit introduction to cell discovery and cell theory cell discovery

  1. Bacteria

  2. Fungi

  3. Virus

  4. Lichens

Show answer
Correct Option: C
Explanation:

  • Schleiden and Schwann in 1839 formulated cell theory. 
  • There are several exceptions to cell theory, e.g., viruses do not have a cellular structure. 
  • They replicate but are non-living particles made up of proteins and nucleic acids. 
  • Only one nucleic acid is found in a virus particle either RNA or DNA.
Thus, the correct answer is option C.
