cleavage (redirected from Cleavage fragment)

cleav·age  (klvj)

n.

1. The act of splitting or cleaving.

2. The state of being split or cleft; a fissure or division.

3. Mineralogy The splitting or tendency to split of a crystallized substance along definite crystalline planes, yielding smooth surfaces.

4. Embryology

a. The series of mitotic cell divisions that produces a blastula from a fertilized ovum. It is the basis of the multicellularity of complex organisms. Also called segmentation.

b. Any single cell division in such a series.

5. Chemistry The splitting of a complex molecule, such as a polysaccharide, into simpler molecules.

6. Informal The hollow between a woman's breasts, especially as revealed by a low neckline.

cleavage [ˈkliːvɪdʒ]

n

1. Informal the separation between a woman's breasts, esp as revealed by a low-cut dress

2. a division or split

3. (Earth Sciences / Minerals) (of crystals) the act of splitting or the tendency to split along definite planes so as to yield smooth surfaces

4. (Life Sciences & Allied Applications / Biology) Also called segmentation Embryol (in animals) the repeated division of a fertilized ovum into a solid ball of cells (a morula), which later becomes hollow (a blastula)

5. (Chemistry) the breaking of a chemical bond in a molecule to give smaller molecules or radicals

6. (Earth Sciences / Geological Science) Geology the natural splitting of certain rocks, or minerals such as slates, or micas along the planes of weakness

cleavage  (klvj)

1. Geology The breaking of certain minerals along specific planes, making smooth surfaces. These surfaces are parallel to the faces of the molecular crystals that make up the minerals. A mineral that exhibits cleavage breaks into smooth pieces with the same pattern of parallel surfaces regardless of how many times it is broken. Some minerals, like quartz, do not have a cleavage and break into uneven pieces with rough surfaces.

2.

a. Biology The series of mitotic cell divisions by which a single fertilized egg cell becomes a many-celled blastula. Each division produces cells half the size of the parent cell.

b. Any of the single cell divisions in such a series.
