Q. Assertion: The mechanical method of protoplast isolation is generally not used for meristematic cells. 

Reason: Meristematic cells are less vacuolated, making them unsuitable for the plasmolysis-dissection principle

Q. Assertion: Barley aleurone cells require treatment with glusulase to release protoplasts. 

Reason: Treatment of these cells with cellulase results in sphaeroplasts, which still possess a residual cell wall.
