Answer:
A) an inability to transport ions, nutrients, and other substances across the membrane
Step-by-step explanation:
Some of the transmembrane proteins present in the plasma membranes serve as carries, channels or pumps. These proteins allow the active or passive movement of charged ions, polar and large substances across the membrane. These substances can not cross the inner non-polar core of the membrane. If a plasma membrane of a particular cell lacks trans-membrane proteins, it would not be able to move the above-mentioned substances in or out of the cells.
