Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
As with many inventions there is no simple answer. The electric cell was invented not discovered. The Daniel cell (1836) is possibly the first example of electric cells, these were an improvement on the Leyden jars (1745), independently invented by Kliest and Musschenbroek. These were more like what we would refer to as capacitors. Volta then improved these further to what we would recognised today as a battery. That is, several 'cells' connected together which he referred to as a 'Crown of Cups'.

Sickle cell anemia was discovered in the 1870's and carried many names, but 1922 it was officially named sickle cell anemia.
He discovered the cell nucleus within cells as one of his major accomplishments

Graphite
Alessandro Volta was known for invention of the electric cell and discovery of methane.

The discovery of the cell was possible due to the invention of the microscope.
The present invention relates to a gamma-electric cell for producing a high-output voltage from a source of radiation wherein the gamma-electric cell includes a central collector constructed of a dense metal and with the central collector encapsulated within an outer layer of dielectric material. A further conductive layer is then disposed on or within the dielectric material so as to provide for a high voltage output between the conductive layer and the central collector upon the reception of radiation by the gamma-electric cell. The invention also includes the use of a plurality of collectors radiating from the central collector throughout the dielectric material so as to increase the collection area and thereby increase the current and/or output voltage. Other aspects of the invention are directed to the method of producing a high voltage output gamma-electric cell by encapsulation techniques using a dielectric material which is castable and curable so as to provide for an intimate contact between the collectors and the dielectric material which surrounds and encapsulates the collectors. Other aspects of the method of encapsulation of the present invention include the use of specific dielectric materials and also the elimination of trapped gases within the dielectric material.
When charges (means charged bodies) move , then we say that an electric current is produced. If charges remain at rest, current is zero. If charge Q moves through a metal in time t , then current I through metal is: I=Q/t; moreever, electric current can also be produced by rate of change of magnetic field through a metal...,
One invention was the cell phone.
i need this for science class!!!!!!!!!! If you do a bit of research, you will find that the answer is "THE MICROSCOPE". Look it up and see who invented it. Research is fun.
Well that was the fist discovered cell membrane
The cell phone was not discovered, it was invented. The man who invented the cell phone was Martin Cooper, who worked as an engineer at Motorola.
