Yes all cell membranes are selectively permeable.

Explanation:

Animal cells are covered over by cell membrane only, but plant cells are covered over by cell wall made up of cellulose in addition to cell membrane.

Cell wall is not selectively permeable as it allows all substances to pass through it.

Cell membrane is always selectively permeable.
