Question

Some solutes are able to pass directly through the lipid bilayer of a plasma membrane, whereas other solutes require a transport protein or other mechanism to cross between the inside and the outside of a cell. The fact that the plasma membrane is permeable to some solutes but not others is what is referred to as selective permeability.

Answer 1

The fact that the plasma membrane is selectively permeable is referred to as selective permeability.

Step-by-step explanation:

• In selective permeability ions and large polar molecules cannot pass through the membrane, on the other hand, hydrophobic molecules and small polar molecules can diffuse through the lipid layer of the plasma membrane.
• This ability helps the sale to regulate the inflow and outflow of substances in and out of the cell.
