NEET 2026, Biology Q86: Structure and Functions of Cell Organelles

NEET2026Biology
Q.

Select the correct statements regarding cell membrane in eukaryotic cell.

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.

Choose the correct answer from the options given below:

  1. A

    C, D and E only

  2. B

    B, C and E only

  3. C

    A, B and D only

  4. D

    A, C and E only

Solution

Mesosomes are extensions of plasma membrane into the cell, but they occur in prokaryotes, not eukaryotes, so statement C is wrong.

Glycocalyx is described on the plasma membrane of prokaryotes; eukaryotic cells do not characteristically have a glycocalyx of the same type, so statement E (as framed here) is incorrect.

Statements A, B and D are correct.
