It refers to the tissue (xylem and phloem) that conducts water and nutrients through the plant body in higher plants.
The evolution of vascular tissue, especially xylem with its rigid water-conducting cells known as tracheids, provided the plant stem with greater support and allowed plants to grow upright to great heights.
Vascular tissue helped plants to live on land effectively. They allowed for an early dominance of these plants on land, giving them the ability to transport water and dissolved minerals through specialized strands of elongated cells that run from the plant root to the tips of the leaves.
