Which of the following structures is not found in a prokaryotic cell?

  1. Mesosome
  2. Nuclear envelope
  3. Ribosome
  4. Plasma membrane

Answer

(2) Nuclear envelope

Solution

As per NCERT, prokaryotic cells have no well-defined nucleus: the genetic material is basically naked and is not enveloped by a nuclear membrane.

⇒ Mesosome (infolding of the plasma membrane), 70S ribosomes and the plasma membrane are all present in a prokaryotic cell.

∴ The nuclear envelope is not found in a prokaryotic cell.
