Answer:
The plasma membrane or cell membrane is the outer covering of all cells but in a plant cell, it is present below the cell wall. It is mainly composed of phospholipid bilayer structure with the embedded proteins. The fluid nature of membranes is due to the lipids. The lipids can be saturated or unsaturated.

Explanation:
The plasma membrane protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.If unsaturated fatty acids are compressed, the “kinks” in their tails push adjacent phospholipid molecules away, which helps maintain fluidity in the membrane. The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at cold temperatures.
