Title: How is the xylem and phloem tissue in a plant adapted to transport sugars and water? Post by: dataplease on Jan 16, 2012 Xylem and Phloem are both part of the vascular structure of plants and are long, hollow tubes. The long, hollow structure of the xylem and phloem make them ideal for water and solute transportation through the use of adhesive forces and capillary action. Phloem are living when they are functional and conduct sugars and other solutes throughout the plant. Sugar will enter phoem at source (leaf when plant is not in a period of growth) resulting in a hight solute concentration. In response to this high concentration H20 will enter the phloem by osmosis. The H2) containing the sugar will then travel through the plant to places of low solute concentration (sinks) Xylem are dead when they are functional and conduct water throughout the plant. Xylem are lined with lignin to provide structural support and are harder than ploem. Hope some of this helps.
