Cleavage is taken from the word 'cleave'. 'To cleave' means to split or break . Thus, the act of splitting or breaking or cleaving is called cleavage. The fissure or division that is formed by this act or such a state of being split is also called cleavage. Cleavage is synonymous to split, break, chink, cleft, crack, crevice, fissure, and division. In mineralogy and material sciences, cleavage is a process of splitting of a crystallized substance in particular crystalline planes. This produces smooth surfaces.
In Embryology, Cleavage is termed as mitotic cell divisions. This cleavage or cell divisions produce a blastula (early embryo) from fertilized ovum (egg). This is also called segmentation. One single division in a series of such divisions is also termed cleavage. In Chemistry, cleavage is splitting of composite molecules into its simpler form. Example: splitting of a polysaccharide molecule.
