Concept:A living semi-permeable membrane is obtained from living cells, while a non-living one is synthetic or processed.
Explanation:A semi-permeable membrane allows certain molecules, especially water, to pass through while blocking others.
Living semi-permeable membranes contain biological plasma membranes from living organisms.
Pig’s bladder, unripe pawpaw fruit, and yam tuber all come from living tissues and act as living semi-permeable membranes.
