Question

The plasma membrane is ______.

• A. permeable
• B. semipermeable
• C. differentially permeable
• D. impermeable

Answer 1

The correct option is C

differentially permeable

The correct option is C

Explanation of the correct option:

1. The permeability of the membrane can be classified as a freely permeable membrane, selectively permeable membrane, impermeable membrane, and semi-permeable membrane.
2. The selectively permeable membrane also called the differentially permeable membrane allows passage of only selected molecules to pass through it.
3. It is a selectively permeable membrane, which permits the movement of only certain molecules both in and out of the cell.

Final answer: The plasma membrane is a differentially permeable membrane.
