Middle lamella is mainly composed of: a. hemicellulose b. muramic acid c. calcium pectate d. phosphoglycerides
Option C. The middle lamella is a layer rich in pectins which cement the cell walls of adjacent plant cells and forms plasmodesmata connections. This pectin-rich layer is made up of calcium and magnesium pectates. This layer cements the cell walls of two adjacent plant cells. It is the first formed outermost layer (cell plate formed during cell division forms the middle lamella or lamellum).
