Final answer:
Grafting joins root section to another plant; Layering forms roots on stems; Cutting creates new plants from stem portions
Explanation:
Grafting is a technique in which a section of the root (the stock) is joined to another plant's stem (the scion) to create a new plant. This method allows favorable stem and root characteristics to be combined.
Layering is another method where stems attached to a parent plant may develop roots, allowing them to become new plants. This process can be assisted by plant propagators to enhance successful propagation.
Cutting involves placing a portion of a stem with nodes and internodes in moist soil to root and produce new plants.
