Q. Statement 1 (Assertion): Protoplasts located in close proximity are more likely to undergo fusion during the washing phase of a PEG treatment.
Statement 2 (Reason): The removal of PEG molecules disrupts the organized structure of the plasma lemma, creating localized instabilities that facilitate membrane merging
