Q.

Which of the following statements with respect to Endoplasmic Reticulum is incorrect ?

  1. A

    RER has ribosomes attached to ER

  2. B

    SER is devoid of ribosomes

  3. C

    In prokaryotes only RER are present

  4. D

    SER are the sites for lipid synthesis

Solution

Prokaryotes lack all membrane-bound organelles, including the endoplasmic reticulum. So the claim that prokaryotes have only RER is incorrect.

The other statements correctly describe ER: RER bears ribosomes and is involved in protein synthesis, SER lacks ribosomes and is the principal site of lipid synthesis.
