The overall charge on the cytoplasmic side of a plant cell plasma membrane is <u>negative.</u>
A plasma membrane is a kind of membrane that separates the inner material of the cell from the outer side material and is also called a cell membrane.
Only in plants and bacteria, a cell wall is present on the outer side of the cell membrane whereas in animals the cell wall is absent.
It also protects the cell material from the outer materials that are harmful in nature.
When an impulse occurs the overall charge on the cytoplasm of the membrane becomes negative.
