What is meant by the cell plasma membrane being selectively permeable?
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay...
What advantage of the cell membrane being selectively permeable?
The membrane acts as a barrier that prevents most things from entering. Small molecules and water can diffuse across the membrane but most proteins and larger molecules cannot. The cell can use this...
How are cell membranes selectively permeable?
A cell membrane (the outer casing or inner casing in a plant cell) is selectively permeable. This is because some materials can pass freely through the cell membrane while others cannot.
How is the membrane selectively permeable?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
