Answer 1

Answer:

1. cutting - A small part of a plant which is removed by making a cut with a sharp knife is called a 'cutting'. A cutting may be a piece of stem, root or even a leaf. The plants like rose, Bougainvillea, Chrysanthemum, grapes, sugarcane, bananas, and cactus, etc., can be grown by means of cuttings.
2. Layering - In this method, a branch of the plant is pulled towards the ground and a part of it is covered with moist soil leaving the tip of the branch exposed above the ground. Many plants like strawberry and raspberry are propagated by the natural layering method.
3. Grafting - Grafting is a method in which the cut stems of two different plants are joined together in such a way that the two stems join and grow as a single point. This new plant will have the characteristics of both the original plants.
4. Tissue culture - The production of new plants from a small piece of plant tissue removed from the growing tips of a plant in a suitable growth medium is called tissue culture.
