Explain why is it important for cells to have a variety of ways to transport materials across the cell membrane. Be specific.

Your answer is read correctly your answer The cell membrane is selectively permeable. It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all.

Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane. Larger molecules such as glucose require a specific transport protein to facilitate their movement across the cell membrane.

The arrangements of lipids in the membrane makes the cell semi permeable .
