What is middle lammalae? |
|
Answer» Middle lamella is the outermost layer of cell wall shared by adjacent plant cells that glues them together. It is composed of polysaccharides called pectins.The middle lamella is cementing layer between the cells. It is made up of Ca and Mg pectates. The basic chemical unit of pectin is galacturonic acid, which has the capability of salt formation with calcium and magnesium (an acid-base reaction). During cell division in plants a thin sheath forms between cell walls of two cells called middle lamellae. |
