Answer 1

Answer:

1. The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. ... If plasma membrane ruptures or breaks down then molecules of some substances will freely move in and out of the cells.

2. The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. ... When the concentration outside the cell becomes low and it is high inside the cell, they moves out
