My husband and I *love* to walk ...for hours and hours, and if we decide to go ahead with this potential trip - I'm going to need good shoes. These days, I have some reasonably good shoes for the most part - but they are 2-3 hour walking shoes, not necessarily good for 6+ hours of tromping around.
In cell biology, selective permeability is the property of a living cell membrane that allows the cell to control which molecules can pass through the membrane, moving into or out of the cell.
However, only the Selectively cells can enter and go out of the cell! Thâ¦is is why the selectively permeable membrane is permeable! A cell membrane (the outer casing or inner casing in a plant cell) is selectively permeable because some materials can pass freely through the cell membrane while others cannot.
