Summary Introduction

To compare: Tension-cohesion and root pressure as mechanisms responsible for the rise of water and dissolved minerals in xylem.

Introduction: Water is very 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 two components: xylem and phloem. The transportation of water and dissolved solutes from roots toward leaves is called the ascent of sap.
