Why Do the Cells Die When the Ambient Temperature Drops

Question

Why do the cells die when the ambient temperature drops to freezing?
A) because of the increased cellular signalling inside the cell
B) because of the inhibition of cell division
C) because of the inhibition of molecule transport across the cell membrane
D) because of the increased metabolic reactions inside the cell

Accepted Answer

When the ambient temperature drops to freezing, the fluidity of the cell membrane decreases, significantly inhibiting the transport of molecules across the cell membrane. This disruption in transport mechanisms can lead to cell death as essential nutrients, ions, and signaling molecules cannot be adequately exchanged.
