Answer:
if a molecule is too large it cannot pass. also it depends on the concentration of a specific substance inside the cell. similarly, if a molecule is polar it cannot penetrate the phospholipid bilayer.
there are proteins that work as channels and pumps that allow these molecules to pass
Explanation:
The polarity of the molecule determines whether a molecule can cross a cell membrane. The correct option is D.
The asymmetric establishment of several cellular components, such as the plasma membrane, cytoskeleton, or organelles, is alluded to as cell polarity.
The polarity of the molecule determines whether a molecule can cross a cell membrane as the cell membrane is composed of phospholipids which are polar in nature.
Thus, the correct option is D.
