What statement explains why oxygen molecules easily diffuse across a cell membrane well glucose molecules do not?

Oxygen molecules are small and nonpolar, allowing them to easily diffuse through the lipid bilayer of the cell membrane without the need for transport proteins. In contrast, glucose is a larger, polar molecule that cannot passively diffuse through the membrane; it requires specific transport proteins to facilitate its movement into the cell. This difference in size and polarity accounts for the varying ease of diffusion for these two substances.
