Minerals that break in irregular, jagged or splintered edges are said to have fracture. Quasi-cleavage fracture is related but distinct from cleavage in the sense that fracture surfaces are not true cleavage planes. (These three properties are listed on the same page due to their comparability, but are each individually discussed). Cleavage on the other hand is the second step in the process of cell division that is responsible for splitting of the parent cell into two . Initially, the zygote splits along a longitudinal plane. Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
