Cell membranes permit small non-polar molecules to pass while blocking small polar molecules

the verdict
COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that cell membranes permit small non-polar molecules to pass while blocking small polar molecules?

Cell membranes are selectively permeable, readily allowing small non-polar molecules to cross the hydrophobic core via passive diffusion while largely blocking polar or charged molecules.
