Look at this image-the water molecules are black. Select the best answer below:
The water molecules are going to move to the right side.
The water molecules are going to move to the left side.
There is going to be no movement of the water molecules.
The salt molecules are going to move to the right side.
What is the definition of Selective Permeability?
The movement of materials across the cell membrane that requires NO ENERGY from the cell.
The movement of materials through (or across) the cell membrane
The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
The movement of molecules from an area of high concentration to a area of low concentration
What is the main function of the cell membrane?
To store genetic information
To provide energy for the cell
To control the movement of substances in and out of the cell
To synthesize proteins
