Specialized Cells in Plants: Vascular Tissue 9 BIO Vascular Bundles • Vascular plants have their tissues organized in vascular bundles in their structures. • Two types: – Xylem- H2O transport – Phloem- glucose transport Xylem • Xylem tissue is designed to draw water up from the roots stems leaves Phloem • Phloem tissue is designed to transport the glucose from the leaves to the rest of the plant. Xylem and Phloem • Work together to draw water up and use water to help distribute glucose to the entire plant. Capillary Action • Hydrogen bonding helps the volume of water in xylem to draw water up from the roots.
