Selectively or differentially permeable 9. Found inside – Page 27(ICSE 2012) Ans. Plasma membrane is selectively permeable membrane or differentially permeable membrane which allows the passage of molecules selectively. b) a cell wall in between. Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis.The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. It is commonly used to detect mycoplasma in cell culture via fluorescence microscopy. b) a cell wall in between. Active transport 15. A solution whose concentration is equal to the cell sap. Solutions which have the same osmotic pressure.
