True or false: both diffusion and osmosis can occur in an open area or across a cell membrane

This is false.
Diffusion can occur under an open area and a cell membrane, but not for osmosis. Osmosis can only occur through a semi permeable membrane, which one example can be the cell membrane. Only water molecules move in osmosis, but diffusion can be any fluid which includes gas or liquids.
