Middle lamella is composed mainly of:
Options
(a) muramic acid
(b) calcium pectate
(c) phosphoglycerides
(d) hemicellulose
Correct Answer:
calcium pectate
Explanation:
Middle lamella is mainly composed of calcium pectate. Calcium is deposited in plants cell walls during their formation it is required for the stability and function of cell membranes and acts as a type of ‘cementing agent’ in the cell walls in the form of calcium pectate’. Calcium pectate is like a glue binding adjacent cells together so if inadequate calcium is not transported during cell formation, tissues become less stable and prone to disintegration.
