The tendency of some minerals or rocks to break along planes of weakness. This weakness occurs because of the nature of the bonds between mineral grains.

The process of cytokinesis in animal cells, characterized by pinching of the plasma membrane; specifically, the succession of rapid cell divisions without growth during early embryonic development tha [..]

1. of a mineral: The tendency of a mineral to split along planes determined by the crystal structure. 2. of a rock: see slaty cleavage

1816, in geology, "action of splitting (rocks or gems) along natural fissures," from cleave (v.1) + -age. General meaning "action or state of cleaving or being cleft" is from 1867. [..]

The splitting or tendency of a crystal to split along definite crystalline planes to produce smooth surfaces. See Cleavage in Mineral Properties for more information.

Multiple definitions. To embryologists, cleavage refers to stages in the development of embryos, when then go from one-cell to two-cell to four-cell embryos and so on.

natural plane of breakage along which consecutive breaks produce smooth, parallel splits.

the line of weakness in a rock along which it will break when put under stress.

The series of mitotic cell divisions that produce a blastocyst from a zygote. © Nature Education

The ability of a rock mass to break along natural surfaces; a surface of natural parting. Also used to refer to the plane or planes along which a stone may likely break or delaminate.

(n) - the tendency of a mineral to break along planes of weakness

The human egg cell is massive in relation to the size of its nucleus

Property of a mineral in which it breaks along smooth, definite surfaces.

The splitting of a mineral along an internal molecular plane.

(n) the state of being split or cleft(n) the breaking of a chemical bond in a molecule resulting in smaller molecules(n) (embryology) the repeated division of a fertilised ovum(n) the line formed by a [..]

The tendency of certain minerals, rocks, etc to break in certain directions (Lesson 27)

The tendency of a mineral to break along weak planes.

Cleavage refers to the mitotic divisions that occur in the zygote during the first 3 days after fertilisation.

The tendency of a mineral to break along weak planes.

A separation between layers of paint, between paint and ground, or between ground and support.

The ability of a rock mass to break along natural surfaces; a surface of natural parting.

Process of releasing a compound from a solid support, thereby permitting assay or analysis of the compound by solution-phase methods. Dissolution of the compound following cleavage, rather than the cl [..]

A reaction that severs one of the sugar-phosphate linkages of the phosphodiester backbone of RNA. It is catalyzed enzymatically, chemically, or by Radiation. Cleavage may be exonucleolytic, or endonuc [..]

The property of a mineral breaking along its crystallographic planes.

A mineral property. The cleavage of a mineral is a smooth, definite plane produced when broken. Best seen and characterized under a light transmitting microscope, but can also be produced easily in a [..]

The splitting or tendency of a crystal to split along definite crystalline planes to produce smooth surfaces. (See Cleavage in mineral properties for more information.)

Cleavage is a physical property of gemstones that is related to structure. It is a break that occurs along certain planes of growth, and is a function of the cohesive properties of atoms, or groups of atoms within the crystal lattice. Cleavage may be described as perfect to poor, and easy to difficult. Any gems having perfect cleavage are more diff [..]

The three-directional separation planes of minerals that are determined by internal atomic structure.

The tendency of a mineral to split along crystallographic planes. Closed circuit

The tendency of a mineral crystal to split along certain planes which are parallel to actual or possible crystal faces, yielding more or less smooth, flat surfaces.

A separation between layers of paint, between paint and ground, or between ground and support. Usually associated with cracks and losses. See flaking.
