Question

........... are embedded on the rough endoplasmic reticulum.

• A. Ribosomes
• B. Lysosomes
• C. Centrosomes
• D. Mesosomes

Answer 1

The correct option is A Ribosomes

a) The endoplasmic reticulum is associated with small dense granules called ribosomes, lying along the outer border of its membrane. They impart a rough appearance to the endoplasmic reticulum. The ribosomes synthesize the protein which is further modified by the endoplasmic reticulum.

b) Lysosomes are known as suicidal bags. They are spherical vesicles scattered in the cytoplasm which contains hydrolytic enzymes that help in intracellular digestion.

c) Centrosomes help to organize microtubules and perform cell division.

d) Mesosomes are folded invaginations in the plasma membrane of a prokaryotic cell which helps to increase the surface area for absorption.

So, the correct answer is option A.
