"1 is true 2 is true 3 is true 4 is true 5 is false, making it the answer Water molecules cannot pass through the cell membrane because the lipids are hydrophobic (meaning that they repel water and won't let water or water soluble molecules to pass through it). In order for osmosis to occur, there must be special proteins called aquaporins on the cell membrane, which provide a channel through which the water molecules can pass."
