  8. (Cleavage (embryology)) In embryology, cleavage is the division of cells in the early embryo. The zygotes of many species undergo rapid cell cycles with no significant growth, producing a cluster of cells the same size as the original zygote. ...
  9. (Cleavage (geology)) Cleavage, in structural geology and petrology, describes the tendency of a rock to break along preferred planes of weakness, caused by the development of a planar fabric as a result of deformation.
  10. (Cleavage (minerology)) Cleavage, in mineralogy, is the tendency of crystalline materials to split along definite crystallographic structural planes. ...
  11. (Cleavage (politics)) Cleavage in political science is a concept used in voting analysis and is the division of voters into voting blocs.
  12. (Cleave (fiber)) A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat endface, perpendicular to the longitudinal axis of the fiber. ...
  13. (cleavage) The act of cleaving or the state of being cleft. [from 19th c.]; The tendency of a crystal to split along specific planes. [from 19th c.]; The repeated division of a cell into daughter cells after mitosis. [from 19th c. ...
  14. (cleave) Flat, smooth surface produced by cleavage, or any similar surface produced by similar techniques, as in glass; To split or sever something or as if with a sharp instrument; To break a single crystal (such as a gemstone or semiconductor wafer) along one of its more symmetrical ...

  20. (Cleavage) refers to the tendency of a diamond to split along the grain parallel to one of its octahedral faces. It is also a term applied to rough diamonds that have at some time been cleaved from a larger stone.
  21. (Cleavage) An inclusion that can be caused by inherent internal strain or a heavy blow struck in parallel to one of the crystallographic planes within a diamond. The cleavage can sometimes reach the surface of the diamond.
  22. (Cleavage) The tendency of a mineral to break along a plane due to a direction of weakness in the crystal.
  23. (Cleavage) (a) The tendency of a crystalline mineral to break in certain definite directions, leaving a more or less smooth surface. (b) The act or process of producing such a break. (c) One of the portions of such a mineral resulting from such a break. ...
