What is "semi permeable membrane"?

Read the given statements and select the correct ones. A membrane which permits the passage of pure solvent molecules to pass through it and not the solute particles is called semi-permeable. A membrane which allows some substances to pass through it more readily than other is known as selectively // differentially permeable. All living biological membranes are perfectly semi-permeable.
