Question 3
What is the essential difference between layering and taking a cutting?
The right answer is the one marked above.
In layering the branch grows roots while still attached to the mother plant. It is fed by the parent throughout the weeks that takes, which is why layering succeeds on plants where cuttings fail.
Cutting the branch off before burying it describes a cutting, not layering. The cambium restriction belongs to grafting, and agar belongs to tissue culture — each is the right fact attached to the wrong method.
