Hydrophobic molecules are permeable to the cell membrane. Anything that is samll and hydrophobic will pass easily. Larger, hydrophilic molecules require a transport protein to allow permeability.

Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
The cell membrane is semi-permeable.
it is not selective permeable. - Cell membranes are selective permeable. Cell walls are fully permeable - which means that it allows all substances/molecules to pass in and out of the cell. It is located outside of the membrane.
selectively permeable or differentially permeable membrane
A "semi permeable" membrane.

Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
The cell membrane is selectively permeable, allowing some molecules to pass through by osmosis
A selectively permeable membrane.
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell

selectively permeable or differentially permeable membrane
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
