Summary Introduction
Introduction: Water is an important requirement for the growth of plants. Plants have developed an effective way for absorption, translocation, storage, and utilization of water. There is a vascular system in plants that conducts transportation of water in plants. Vascular system comprises of two components: xylem and phloem. The transportation of water and dissolved solutes from roots toward the leaves is called the ascent of sap.
