THIS HAPPENS AUTOMATICALLY WITH A CELL IF ITS IS PERMEABLE TO THE AND IF THERE IS A DIFFERENCE IN OF THE MOLECULES ON EITHER OF THE MEMBRANE. THIS IS .

movement; cell membrane; molecules; concentration; side

THIS IS know as diffusion

Explanation:

Diffusion is the movement of molecules from the side of the membrane with a higher concentration to the side of the membrane with a lower concentration. Facilitated diffusion is a process that occurs if the cell membrane is permeable to these molecules and if there exists a difference in the concentrations on the two sides of the membrane. This mechanism is also known as passive transport because no energy is needed for the movement of molecules across the membrane.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape
