The cells in vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.
Xylem tissue carries water and nutrients from the roots to the leaves. Phloem tissue carries sugar from the leaves to other cells of the plants. Non vascular plants are plants that lack tissues that transport water, nutrients, and sugar.
