A membrane which lets pass some materials and stops other is known as a selectively permeable membrane.
It is osmosis .
the chemical nature of the membrane
It makes it harder for viruses and free radicals to reach the nucleus.
active transport
Osmosis movement of water from high concentration to low concentration.
It is important because, if the cell membrane was not selectivly permable, we would not be able to do the things today.
Selective breeding.
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
