Explanation:
Detailed explanation-1: -Water passes through the membrane in a diffusion process called osmosis.
Detailed explanation-2: -Thus, gases (such as O2 and CO2), hydrophobic molecules (such as benzene), and small polar but uncharged molecules (such as H2O and ethanol) are able to diffuse across the plasma membrane.
Detailed explanation-3: -While diffusion transports materials across membranes and within cells, osmosis transports only water across a membrane.
