Sexual reproduction in plants is called pollination. This process occurs in the flowers that have the male organs (stamens) and the female organs (pistils). When the gametes join, they form a diploid zygote that eventually will develop into a new organism.
Some plants reproduce through asexual reproduction, this means that the plant generates new organisms that are identical to the original plant. There are several ways in which plants can reproduce asexually.
One of these processes is called layering, in which a branch of the parent plant touches the soil, where it does it develops roots and can, later on, be cut off from the parent plant, forming a new independent plant.
The process described to reproduce the strawberry is asexual, and the resulting plant is identical to the parent plant.
