Why is it important for the cell membrane to be selective in allowing material into out of the cell?

Semi-permeability of cell membrane protects the internal parts and functions of the cell.

Explanation:

It adds to the sense that cell membrane houses the cell, which means not all external materials (e.g. molecules) can be penetrated within.

Cause Fluidity is they allow membrane proteins rapidly in the plane of bilayer and it permits membrane lipids and proteins to diffuse from sites where they are inserted into bilayer after their synthesis.

Explanation:

Fluidity is important for many reasons: 1. it allows membrane proteins rapidly in the plane of bilayer. 2. It permits membrane lipids and proteins to diffuse from sites where they are inserted into bilayer after their synthesis.

Plasma membranes must allow certain substances to enter and leave a cell, and prevent some harmful materials from entering and some essential materials from leaving. In other words, plasma membranes are selectively permeable—they allow some substances to pass through, but not others
