B. When beetroot cells are placed in a solution with cellulase, the solution remains clear.
Cell membrane are not destroyed or damaged as cellulase digests cellulose, rather it damages the structure of the cell wall.
In conclusion, even though the Beetroot cell wall has been damaged, the lack of change in the color of the solution suggests that the betalain is not leaking out thereby refuting the claim that the alternative hypothesis that selective permeability is a consequence of the cell wall.
true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
