Which of the following materials is not a living semi-permeable membrane?
Answer Details
A semi-permeable membrane is a barrier that allows some substances to pass through, but not others. All living cells have semi-permeable membranes that regulate the exchange of substances between the cell and its environment.
Out of the four options, the material that is not a living semi-permeable membrane is "sheet of cellophane". Cellophane is a synthetic, non-living material that is often used as a packaging material or for wrapping food. It does not have the ability to regulate the exchange of substances like a living semi-permeable membrane.
