The property that is being described is cleavage. Cleavage refers to the ability of a mineral to break along smooth, flat planes, which is typically characteristic of the mineral's internal structure. In contrast, fracture refers to a rough or irregular break, and hardness, density, and other properties are not related to the manner in which the mineral breaks when struck.
