Ans. There are several methods of plant propagation, including sexual and asexual methods. Sexual propagation involves the use of seeds, where the male and female reproductive cells combine to form a new plant. Asexual propagation, on the other hand, does not involve seeds and can be done through methods such as cuttings, layering, grafting, and tissue culture. Cuttings involve taking a part of a plant and encouraging it to develop roots and grow into a new plant. Layering involves bending a branch to the ground and allowing it to root before separating it from the parent plant. Grafting involves joining a scion (top part of one plant) with a rootstock (the root and lower stem of another plant) to create a new plant with desirable traits. Tissue culture is a laboratory technique where small pieces of plant tissue are grown in a sterile medium to produce new plants. These methods allow gardeners and farmers to reproduce plants with desirable traits or to propagate rare or endangered species.
