The middle lamella is: a layer that cements together the: primary cell walls of two adjoining plant cells. It is the——first formed layer——to be, deposited at the time of cytokinesis. The cell plate that is formed during cell division itself develops into middle lamella. Or lamellum. The middle lamella is made up of calcium. And magnesium pectates. In a mature plant cell it is the outermost layer of cell wall.
In plants, the pectins form a unified and "continuous layer between adjacent cells." Frequently, it is difficult——to distinguish the "middle lamella from the primary wall," especially in cells that develop thick secondary walls. In such cases, "the two adjacent primary walls and the middle lamella." And perhaps the first layer of the secondary wall of each cell, "may be called a compound middle lamella." When the middle lamella is degraded by, enzymes, as happens during fruit ripening and abscission, the adjacent cells will separate.
