Explanation

The correct answer is option 4 i.e. Both I and II.

  • The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism.
  • The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

  • The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
