The incorrect pair is (ii) SER — Lipid and cellulose synthesis because SER synthesises lipids but not cellulose. Ribosomes make proteins and lysosomes digest materials correctly.
Identify the pair that incorrectly matches the cell organelle with its function. (i) Ribosome – Protein synthesis (ii) SER — Lipid and cellulose synthesis (iii) Lysosome — Digestion of foreign agents

The incorrect match is (ii) SER — Lipid and cellulose synthesis. Smooth endoplasmic reticulum synthesises lipids but does not produce cellulose. Ribosomes correctly perform protein synthesis and lysosomes digest foreign substances and wastes. Therefore, option (ii) is incorrect, while the other pairs are correctly matched with their functions.
