Why is the plasma membrane selective? a. so water cannot enter or exit the cell b. so waste products do not enter the cell c. so lipid-soluble molecules do not enter or exit the plasma membrane unassisted d. so large molecules can pass through the plasma membrane unassisted

Option (D).

Explanation:

Plasma membrane is made of the lipid bilayer and proteins are embedded or inserted in the membrane. Carbohydrates are attached with the proteins and lipids in the membrane.

The plasma membrane is the selectively permeable membrane that allows the movement of selected particles only. The large molecules pass through the plasma membrane unassisted and special molecules are required for their transport.

Thus, the correct answer is option (D).
