Hello!
• Cell membrane is the outer most layer of animal cell
• It is also called as Plasma Membrane
• The material which are required for the cell are passed in through it
• The materials which donot require for the cell are passed out through it
• It only allows the selective materials
• So, it is called as selectively permeable membrans
• By this, we can say that cell membrans transports actively!
