Unhomogenized milk and cream contain butterfat in microscopic globules. The parallel plates provide more surface for suspended oil droplets to coalesce into larger globules. Ice cream is a colloidal emulsion having dispersed phase as fat globules. Isolated small dark nebulae are called Bok globules. Butter contains fat in three separate forms&colon; free butterfat, butterfat crystals, and undamaged fat globules. Lipid bodies and carotenoid globules surround the plastid. They are composed of solid fat globules, dispersed in protein solution. Complex of apical lipid globules are also involved in gravipereception. This stalk is a prominent example of evaporating gaseous globules, or 'EGGs'. Where Leeuwenhoek described "small spheroid globules", they observed yeast cells undergo cell division. These sources were interpreted as partly ionized globules (PIGs). The pores are spaces between the globules filled with water. These clusters rise faster than individual globules can. These types are called "cometary globules" (CG). A liver biopsy will show abundant PAS-positive globules within periportal hepatocytes.
