Electric cells:

• Supply energy to electrons for movement in an electric circuit.

• Store chemical energy and convert it to electrical energy.

• Electrons flow from one material to another provides an electric current.

• Different electrodes and electrolytes produce different chemical reactions affecting the battery’s functionality and energy storage capacity.

Fruit cells:

• Similar to a regular battery, consisting of copper and zinc nails and lemon juice as the electrolyte.

• Electrode connections cause chemical reactions allowing electron flow in the external circuit.
