As with the shutter speed, the aperture also affects the sharpness of your picture, but in a different way. Changing the aperture changes the depth of field, the depth in a scene from foreground to background that will be sharp in a photograph.
With a narrow aperture (so a high number like f/22), the depth of field is much greater, which is useful for things like landscape photography-it will limit the amount of light reaching your sensor, so you will get slower shutter speeds, which makes a tripod handy.
