Summary Introduction
Introduction: Vascular system is a system in plants where the conducting tubes, such as xylem and phloem are present. The xylem vessel helps in transporting the water and the minerals from the roots to the leaves, and the phloem vessels are involved in transporting the prepared food (glucose) from leaves to all parts of the plants.
