Detailed explanation-1: -Fragmentation is a very common type of vegetative reproduction in plants.

Detailed explanation-2: -Answer. Splitting a root system into two more pieces that will each become new plants is called. Separation and division.

Detailed explanation-3: -Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant (usually an herbaceous perennial) is broken up into two or more parts. Both the root and crown of each part is kept intact.

Detailed explanation-4: -Division is a simple means of vegetative propagation for plants that produce suckers, stolons, bulbs, tubers or rhizomes. To propagate by division, dig up the plant and divide it carefully using a spade or secateurs.

Detailed explanation-5: -The line between ‘division’ and ‘separation’ is delicate. The examples mentioned above are of propagation by division. Whereas in separation, the rooted or unrooted parts of the plant are detached from the main plant on maturity. These start to develop a new plant in the next season.
