mitochondria in animals and chloroplasts in plants (these produce ATP [adenosine triphosphate] which is coupled to endothermic reacitons to provide the necessary activation energy)
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
Carbohydrates
A cell's main souce of energy is glucose.
glucose
solar light is the source of energy for a solar light
Glucose is a sugar, so yes it is a source of energy.
ATP is called the energy source (battery) of the cell.
mitochondria
ATP
Mitochondria
All cells have mitochondrea they are hte energy source for the cell All cells have mitochondrea they are hte energy source for the cell
if the cell is a plant cell then the sorce of energy woukd be light. if not there is some kind on food sorce
