* Crystallography: "The cleavage planes in the diamond crystal were easily identified under the microscope, revealing its characteristic cubic structure."
* Geology: "The rock formation exhibited cleavage, indicating that it had been subjected to intense pressure, causing the mineral layers to separate along distinct planes."
* Biology: "During cleavage, the fertilized egg undergoes rapid cell division, forming a solid ball of cells called a morula."
* Cell Biology: "The cleavage furrow, a constriction in the plasma membrane, forms between the daughter cells during cytokinesis."
* Chemistry: "The molecule underwent cleavage at the carbon-carbon bond, resulting in the formation of two smaller fragments."
Remember to consider the specific context and ensure the meaning of "cleavage" aligns with the scientific field you're referring to.
