| A. | The endomembrane system includes Golgi complex, endoplasmic reticulum and mitochondria. |
| B. | Rough endoplasmic reticulum bears ribosomes on its surface. |
| C. | Both mitochondria and plastids have circular DNA. |
| D. | A network of microtubules, microfilaments and intermediate filaments present in the cytoplasm is called cytoskeleton. |
| E. | Mitochondrion is a single membrane-bound structure. |
| A. | Membrane of human RBCs has approximately 52% protein. |
| B. | Major phospholipids are arranged in a bilayer. |
| C. | Extensions of the plasma membrane into the cell form mesosomes. |
| D. | Tails towards the inner part of lipids are hydrophobic and thus protected from aqueous medium. |
| E. | Glycocalyx is present on the outer surface of the plasma membrane. |
