Xylem

Xylem is a transport tissue found inside vascular plants. The function of the xylem is to transport water and occasionally nutrients from the roots up to the rest of the plant. It can accomplish this either through cohesion, which is the attractive force between molecules, or transpiration, which is the evaporation of water on the surface of leaves. The celery shown above highlights the xylem while also demonstrating its function. The celery's xylem was able to transport the colored water up the stalk through cohesion. As a result, we can now see the areas in which water and nutrients are transported through a celery plant.
