Not sure exactly what you are talking about.
Strawberry plants need roots in order to grow. The term "bare root" strawberry means that the strawberry plants are shipped to you, 'bare root', without soil. When you recieve them, you prepare the soil where you want to plant them, soak the plants with their roots to hydrate them. Then you plant them.
If you are asking about growing plants without a root system, there is therefore no way for the plants to absorb water. That job is performed by the roots.
