The plant cells have the cell membrane line in the inside of the cell wall. The cell wall provides the turgidity to the cell. The cell wall is dead and allows all substances to pass freely through it whereas the cell membrane is alive and selective. This is the case also for the cell membrane of the animal cells. The only difference is however that the cell membrane is the only layer around the cell unlike the cell wall that is part of the plant cells. The cell membrane is alive and selective as we know. This means that it is semi-permeable. This is called a semi permeable membrane. Semi permeable means that it is a layer or a surface that allows only certain particles to pass through but not...
