I would guess hydrophillic chemicals can pass through.© BrainMass Inc. brainmass.com October 9, 2019, 4:40 pm ad1c9bdddf
Wrong way round! The phospholipid bilayer is hydrophobic. The ease with which a molecule passes through the cell membrane depends on how easily it will mix with the lipid part of the phospholipids. This comes down to its charge or its size. To put it simply- small and/or hydrophobic molecules can pass freely through the phospholipid ...
The solution determines what types of chemicals can pass through phospholipid portions of the cell membrane and why.
