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.Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).n higher plants thylakoids are organized into a granum-stroma membrane assembly. A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana.
