1. The answer is cutting. It is a method of artificial propagation in plants wherein the stem with a leaf attached is placed in a suitable medium, for example, moist soil so it will form its roots.
2. The answer is Grafting. Grafting is a method of artificial propagation in plants where the stem of the desired plant is grafted onto another plant called the rootstock. Grafting is done by cutting in an oblique way the two plants to be combined together, placed close to each other and then held together.
3. The benefits of artificial propagation are that plants will mature faster since they are growing on already mature or adult plant parts. Also, the new plant is known to be stronger than that of a seedling.
