What is the function of a cell’s selectively permeable plasma membrane? a) it the cell to manufacture proteins. b) it regulates the amount of atp the cell produces. c) it regulates what materials enter and leave the cell. d) it packages and stores most of the material in a cell.

What is the function of a cell’s selectively permeable plasma membrane? C) It regulates what materials enter and leave the cell.

Selective permeability is the cellular membranes property that only allows certain molecules to enter or exit the cell.  In other words it regulates what materials enter and leave the cell. The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. All of this is depend on the molecule size and the concentrations on either side of the membrane

A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by active or passive transport.

Active transport is require the cell to expend energy to move the materials, whereas the passive transport can done without using cellular energy.

The advantage of selectively permeable plasma membrane is the bigger and toxic molecules which might be potentially very harmful for the cell can be prevented from entering the cell  All of this is dependent on the size of the molecule and the concentrations on either side of the membrane
