Cleavage is the tendency to break along flat surfaces, and fracture is the tendency of a mineral to break into irregular pieces.
It would be important because cleavage is a tendency of some minerals to break along smooth, flat surfaces.
Gold does not have a cleavage it has a fracture: The type of fracture is hackly or jagged. Cleavage usually relates to crystals (although cleaving crystals can also be made to fracture too).
Cleavage is a mineral's tendency to break along flat, parallel surfaces (cleavage planes). Excellent cleavage direction reflects light in one direction, it is considered basal, or book cleavage. Biotite and muscovite have excellent cleavage. Good cleavage reflects light in one direction from a set of many small flat surfaces, augite and gypsum are examples. Poor cleavage directions reflect light form surfaces that are hard to detect, and this is true for sulfur.

Cleavage.
Mica forms flat prisms that readily brakes into flakes.

Cleavage is the breaking of a mineral along flat surfaces. Fracture, on the hand is just the chipping or "fracture" of a mineral.Cleavage is the tendency to break along flat surfaces, and fracture is the tendency of a mineral to break into irregular pieces.
