Question

The cell membrane controls the traffic of molecules into and out of the cell, prevents the entry of toxic material into the cell and permits selective uptake of nutrients. Which property of the membrane can this be attributed to?

Answer 1

It is the presence of a semi-permeable / selectively permeable membrane that can be attributed to the cell's ability to controls the traffic the flow of molecules into and out of the cell, to prevent the entry of toxic materials into the cell and to permit selective uptake of nutrients.
