8. REASON FOR THE DIFFERENCE IN CHARGES ON BOTH SIDES OF THE PLASMA MEMBRANE.

9. ARRANGE THE FOLLOWING IN CORRECT ORDER

• This is due to the difference in the distribution of certain ions.

• This momentary charge difference stimulates its adjacent parts and similar

changes occur there too.

• The outer surface of the plasma membrane of the neuron is positively

charged and the inner surface is negatively charged.

• As this process proceeds, impulses get transmitted as electric charges

• When stimulated, the distribution of ions in that particular part changes and

hence the inner surface becomes positively charged and the outer surface

becomes negatively charged.
