Explanation
Solution
Middle lamella is a thin, amorphous and cementing layer between two adjacent plant cells. Middle lamella is the first layer which is deposited at the time of cytokinesis. It is made up of calcium and magnesium pectates. The softening of ripe fruits is caused by partial solubilisation of pectic compounds to produce jelly-like consistency.
