The statements that are false about the cell membrane are:

B (which states that all materials can pass freely back and forth across the membrane) and

C (Water will repel off of the surface of the cell membrane because the phospholipid heads are hydrophobic)

The cell membrane is a defined as a flexible membrane that is made up of mainly proteins and lipids.

It provides the following function to a cell:

  • The presence of a double phospholipid bilayer controls the movement of substances in and out of the cell.
  • It prevents the cell contents from escaping to the exterior.
  • it contains carbohydrates that helps to identify a particular cell.

Therefore all materials cannot pass freely back and forth across the membrane.

The phospholipid bilayer consist of hydrophilic (water loving) heads and hydrophobic (water fearing) tails.

The hydrophobic heads covers the surface and the interior of the cell membrane while the hydrophilic tail is found within the cell membrane.

Therefore water will not repel off the surface of the cell membrane because the phospholipid heads are hydrophilic.
