Chapter 27, Problem 8SQ
Summary Introduction
Concept introduction: Vascular bundle is a part of transport system in vascular plants. Xylem and phloem are the two tissues present in the vascular bundles. In addition to this, supporting and protective tissues are also present in the vascular tissue. The vascular tissues in the stems are called vascular bundle and the vascular tissue in the roots are called vascular cylinder. The vascular tissue structure varies in both
