What is the benefit of the plasma membrane being selectively permeable? It allows any substance through the membrane, ensuring that the cell has all the nutrients it requires. It guarantees that the cell will not grow so much that it ruptures. invading pathogens from infecting the cell.

The benefit of the plasma membrane being selectively permeable is primarily that it regulates the movement of substances in and out of the cell, allowing the cell to maintain homeostasis. This selective permeability ensures that essential nutrients can enter the cell while waste products and harmful substances can be kept out or expelled. Among the options you provided, the most accurate benefit related to selective permeability is that it helps prevent invading pathogens from infecting the cell. By controlling what can enter, the plasma membrane plays a crucial role in protecting the cell from potential threats while allowing it to take in necessary substances for survival and function. The other options you mentioned are not accurate representations of the benefits of selective permeability. It does not allow any substance through indiscriminately, nor does it directly prevent the cell from growing too large.
