Q: Assertion (A): An osmoticum must be added to the medium during the isolation of protoplasts.

Reason (R): Protoplasts lack a cell wall and are prone to bursting without osmotic stabilization.

Q. Assertion (A): Co-culturing is a vital technique for the regeneration of recalcitrant protoplasts. 

Reason (R): Fast-growing protoplasts in the medium secrete diffusible substances that stimulate cell wall synthesis in neighboring cells.
