It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties.

no!, this is false! prokaryotes don't have membrane-bound nucleus!

It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.

  • no!, this is false! prokaryotes don't have membrane-bound nucleus!


    so, for this we only needed to know that prokaryotes DON'T have a membrane-bound nucleus (and this is also perhaps their most important property)
