What plugs provide the spark that ignites the air/fuel combination, resulting in the explosion that causes the engine to generate power?

Spark plugs are little plugs that generate an electrical arc between two leads that are not in contact but near enough that energy can jump the distance between them. The spark plugs and the electrical equipment that drives them make up the ignition system.
