Question

How does the cell membrane help maintain homeostasis for the cell?
A
By providing a circular structure for all cells
B
By making proteins to provide the cell with energy
C
By regulating the transport in and out of the cell
D
By storing food as future energy for the cell

Answer 1

C — By regulating the transport in and out of the cell.
The cell membrane is selectively permeable, using channels, carriers and transport processes (diffusion, osmosis, active transport) to keep the internal environment stable.
