Answer 2

The required "option  (d) plasma membranes" is correct.

Explanation:

The cell wall is usually dead and it cannot regulate the transport of materials across it. The cell wall is fully permeable.

On the other hand, a plasma membrane or cell membrane is living and regulates the flow of ions across it. The flow of ions occurs through special ion carrier and channel proteins present in the plasma membrane.

Ion carriers are located in plasma membranes.

Thus, the required "option  (d) plasma membranes" is correct.
