Answer:
1. Grafting is taking tissue from one plant and combining it with the tissue from another. This is done by cutting off a scion, or branch, from a species with desirable stems, leaves, and buds from one plant. Meanwhile, part of a branch is removed from a different species that has desirable roots. The scion is glued where the branch was removed. The scion gets nutrients from the roots of the second species. Commonly grafted plants are apple, peach, pear, and pecan trees and grapevines.
2. Layering is creating two plants getting roots to grow from a branch and cutting the connection from the parent plant. Branches, or stems of a plant, are bent downward while still attached to the parent plant and buried in the soil. Adventitious roots grow in the soil from the branch. Eventually, the branches cut off from the original plant and can grow on its own. This can be done with blackberry and bonsai plants.
3. Cutting is very similar to layering except that a branch with buds is completely removed (i.e. cut) from the parent plant. One end of the cutting is placed in soil. Adventitious roots grow from the buried end. It is one of the most popular forms of vegetative propagation and can be done with plum trees, pineapple plants, olives, roses, and fig trees.
