A. It allows substances to go into the cell, and it filters them when they exit.
B. It allows some substances to move in and out, and it keeps others out.
C. It allows some gases and liquids to pass into the cell, and then prevents them from leaving.
D. It allows water to move in and out, but it prevents gases from passing through.
