Answer:
vegetative propogation
Step-by-step explanation:
Vegetative propagation or vegetative reproduction is the growth and development of a plant by asexual means. This development occurs as a result of fragmentation of a part of the plant or the growth of specialized vegetative parts. Vegetative propagation involves reproduction through vegetative (non-sexual) structures, while sexual propagation is accomplished through gamete production and fertilization.
An example of this can be seen in the question above, where strawberry plants usually reproduce by making corridors, which are miniature versions of themselves, that grow from their parents' roots and stems.
