Mongoloid is a term for certain asians. They share outward traits like epicanthic folds and fattier cheekbones for example. This caused people in the west to associate it with down-syndrome. After a while people realized the unfortunate implication and renamed the medical term âdown-syndromeâ instead.
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergrana thylakoids or lamellae. Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition.
