Correct Answer:
calcium pectate
Explanation:

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.
