Whether a molecule can cross the plasma membrane depends upon the

• A. Size of the molecule
• B. Shape of the molecule
• C. Charge of the molecule
• D. All of these

Answer 1

The correct option is D All of these

The plasma membrane of a cell is semipermeable and hence allows only the transport of selective molecules. The ability of a molecule to cross the cell membrane depends on factors like the size, charge, and the shape of the molecule.

So, the correct answer is 'All of these'.
