Question

In eubacteria, a cellular component that resembles eukaryotic cell is

• A. Cell wall
• B. Plasma membrane
• C. Nucleus
• D. Ribosomes

Answer 1

The correct option is B Plasma membrane

• Prokaryotic cells have primitive karyon, i.e. primitive nucleus, not having its own nuclear membrane.
• The prokaryotic cell wall is made up of peptidoglycan while the eukaryotic plant cell wall is made up of cellulose.
• The eukaryotic fungal cell wall is made of chitin.
• Prokaryotic cells have 70S ribosomes while eukaryotes have 80S ribosomes in their cytoplasm.
• The cell membrane structure is essentially the same in a prokaryotic and eukaryotic cell and made up of a phospholipid bilayer.

So, the correct answer is 'Plasma membrane'.
