Explanation / Answer

A. Bacterial Cell : Archaeal Cell

Bacteria have only one ribosomal RNA Polymerase while archaea have three ribosomal RNA polymerases. So option “first” is correct i.e. look for different types of ribosomal RNA’s, a defining deference between bacteria and archaea.

B. Rough ER : Smooth ER

Rough endoplasmic reticulum has the ribosome on their surface and smooth endoplasmic reticulum lacks the ribosome. So option “last” is correct i.e. look for the presence of ribosomes, which are found on rough ER but not on smooth ER.
