Accuracy is when you hit as close as to the target as you can and precision is when you are on point

Granules on the photosphere of the Sun are caused by convection currents (thermal columns, Bénard cells) of plasma within the Sun's convective zone. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
I hope this helps!!!! :)
