Vegetative reproduction
Step-by-step explanation:
The type of reproduction described in the illustration is vegetative reproduction.
Vegetative reproduction is a type of asexual reproduction during which a new organism grows from the fragments of the parent organism. There are different methods of vegetative propagation in plants including stolons, bulbs, tubers, corms, etc.
The horizontal stems that give off plantlets that eventually grow to become a clone of the mother plant are the ones known as stolons.
