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?

Carbohydrates present on the membrane

Lipid bilayer of the membrane

Membrane fluidity

Semi-permeable nature of the membrane

Answer 1

Answer 2

The cell membrane is a bi-layer its outer surface is hydrophilic and inner surface is hydrophbic so the substances that pass through it have to be sufficiently hydrophobic and hydrophilic in order to pass it and it also has small openings in it which allows the free exchange. D, since it is semi-permeable then it will be able to control what enters and leaves.
