What allows material to pass in and out the cell?

Answer 1

what allows all materialsto move in and out of the cell Diffusion and osmosis are natural processes of molecules moving in and out of cells from an area of low concentration to one of high concentration across a semi permeable membrance. This requires no energy. Active transport is used to transport molecules against the concentration gradient, and requires the expenditure of energy. Hope that's what you wanted.

Answer 2

the cell membrane of the cell allows materials to pass in or out..but it does not allow all substances to enter or exit the cell..it is very specific about the substances..that is why it is also called the semi-permeable membrane.

Answer 3

Cells have a semi-permeable membrane that regulates the movement of materials in and out of the cell. Small molecules like oxygen and carbon dioxide can passively diffuse through the membrane, while larger molecules may require specific transport proteins to facilitate their passage. Additionally, some materials may be actively transported through the membrane using energy.
