Depolarisation
A membrane depolarization is a decrease in the potential difference between the outside of a cell and the intracellular medium, on either side of the plasma membrane, most often due to a positive ion input (Na +, Ca ++, etc.) inside the cell or sometimes due to the release of chloride ions, and involved in the mechanisms of transmission of nerve impulses and muscle contraction.
Hyperpolarization:
The depolarization is followed by a repolarization, thanks to the output of an equivalent quantity of ions k + which causes the return to the state of equilibrium. Then there is a hyperpolarization due to the output of more k + ions than Na + ions, because the potassium channels are slow to close. Finally there is a return to the resting potential.
Hyperpolarization is a term opposite to that of depolarization, it refers to values lower than that observed during the resting potential.

Answer: A plant root is an example of an ORGAN.
Explanation:
Organ consist of specialized cells that come together to perform similar function.
Plants have different organs which are leaves, stems, and reproductive organs which perform specialized functions.
Leaves, stems and roots are vegetative organs of the plants while flowers,seeds and fruits are reproduce structures.
Roots help to anchor the plant to the soil, they absorb nutrients and water and transport them to the stem.
The word 'science' is derived from the Latin word 'scientia' which means knowledge. Therefore, science is about gaining knowledge either through observing, studying, experience, or practice. Entire knowledge acquired through science is about discovering truths, finding facts, uncovering phenomenon hidden by the nature.
