89. The isolation of a plant cell protoplast requires treating healthy plant tissue with an enzyme cocktail designed to digest the extracellular matrix without harming the plasma membrane. This specialized mixture must contain

A. Proteases and nucleases
B. Cellulase and pectinase
✓
C. Lipases and amylases
D. Amylases and caspases

📝 Explanation

Cellulase breaks down the cellulose microfibrils, and pectinase dissolves the middle lamella, releasing wall-free protoplasts.
