1. It is a way of reproduction in which vegetative organs of plants produce new individuals. For example, the creeping branches of strawberries, the roots of thistles, the tuberous roots of sweet potatoes, the leaves of begonia, and the rhizomes of bamboo, reed, white spear and lotus are all natural asexual reproduction. Propagation methods commonly used in agriculture, forestry and horticulture, such as rooting, cutting, layering and grafting, also belong to asexual reproduction. Artificial vegetative propagation is to separate a part of plant vegetative organs from the mother body and make them develop into new individuals. For example, separating plant tissues and cultivating them into plants in laboratory test tubes is a method of artificial asexual reproduction. Asexual propagation can make offspring keep the excellent characters of their parents, so this propagation method is used in seedling breeding of flowers, fruit trees, trees and crops. 2. Bud propagation is a kind of asexual propagation. Parents produce offspring through cell division, and the bud grows in a certain part of the mother, but the offspring (bud) does not leave the mother immediately, but connects with the mother and continues to receive nutrition from the mother until the individual can live independently. For single-celled organisms, one of the differences between it and fission is unequal division. For multicellular organisms, it is a bud formed by local cell division, but both buds and organisms are multicellular. As can be seen from the above, rooting is vegetative propagation.
