Answer :

the plasma membrane of an excitable cell is more permeable to potassium ions because there are more non-gated channels for K+ than Na+.

The plasma membrane, also known as the cell membrane, safeguards the cell. It also keeps a consistent climate within the cell. And that membrane serves a number of purposes. One function is to bring nutrients into to the cell, the other is to transport harmful chemicals out of the cell. Proteins and lipids are being used to synthesise cell membranes. Endoplasmic reticulum plays a key role in membrane biogenesis. The type of cell membrane greatly influences the cell's function and structure. It safeguards the internal parts of the cell, including that of the nucleus.
