Meaning of selectively permeable membrane
WebApr 12, 2024 · Cell membranes are considered selectively permeable; Some molecules like water can freely pass in and out to regulate solute concentration within the cell, other molecules such as Sodium (Na+), Potassium (K+), carbon dioxide (CO2), hormones and growth factors are regulated. Of course, some molecules are not allowed in at all.
