2. Polar molecules and ions need a transport protein to
diffuse across the cell membrane.
TRUE
FALSE

Answers

Answer:

True

Explanation:

Only small hydrophobic nonplar molecules can go through the hydrophobic interior of the phospholipid bilayer. Therefore, polar molecules and ions need transport proteins to diffuse across the cell membrane, also called facilitated diffusion. An example is water, which is polar, and through osmosis diffuses through transport proteins called aquaporins.
