Answer:
The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
Answer: The cell membrane acts as a selective barrier for the entry and exit of the material from the cell.
Explanation: The proteins present in the cell membrane are specific to the material and they allow the entry or exit either according to the concentration gradient, for example, channel and carrier proteins or against the concentration gradient through the use of energy, for example, pump proteins. The lipid bilayer prevents the entry and exit of polar and large-sized material.
