Question

Why is it advantageous for the cell membrane to be fluid in nature?

Short answer

The fluidity of the membrane allows membrane proteins rapidly in the plane of the bilayer. It also permits membrane lipids and proteins to diffuse from sites where they are inserted.

Step-by-step solution

Introduction

The cell membrane or the plasma membrane gives a protection activity to the cells. It can also provide a stable environment inside the cell and it also had several different functions like transporting nutrients into the cell and also transporting toxic substances outside the cell.

Explanation

The plasma membrane has flexibility with a combination of phospholipids, cholesterol, and proteins.

It is very flexible in nature that allows the cells to alter the shape and this is the primary function of the cell membrane. It allows membrane proteins in the plane of bilayers and permits lipids and proteins to diffuse at the inserted site. It also contains markers to allow the cells to identify one another during an early developmental stage.
