Final answer:

Propagation by stem cutting involves placing parts of a stem in water or soil to grow new plants. Layering and aerial layering are methods of plant propagation where stems are manipulated to generate new roots and create new plants.


Explanation:

Propagation by stem cutting is a method of plant propagation where parts of a stem containing nodes or internodes are placed in water or moist soil to grow new plants. An example of this is when you cut a healthy branch of a plant and place it in water until roots develop, creating a new plant.

  1. Layering: It is a process in plant propagation where a stem is bent and covered with soil to generate new roots, resulting in a new plant. This method promotes a high success rate by preventing water stress and carbohydrate shortage.
  2. Aerial layering: A type of layering where the stem is still attached to the parent plant but forms roots where it touches a rooting medium. Once rooted, the stem becomes a new plant, aiding in vegetative propagation.
