This book is outcome of Plant anatomy research study work which mainly focuses on plant transport tissues known as xylem. Types of xylems, their functions and presence in different part of plant body discussed in various chapters.The xylem and the phloem make up the vascular tissue of a plant and transports water, sugars, and other important substances around a plant. What is commonly referred to as 'sap' is indeed the substances that are being transported around a plant by its xylem and phloem.The separation between plants that have veins and plants that do not, is one of the great divides within the plant kingdom. This separates plants into vascular and non-vascular plants. Xylem tissue mostly transport and other dissolved compounds from roots to stems and leaves. The last two chapters of the book deals with case study of xylem vasculature development in stem, root and leaves of some Apocynaceae plants.This fascinating book will intrigue readers who love to explore plant anatomy. With colorful, engaging descriptions of xylem, plenty of tables full of data this book provides wonderful information for study of xylem to undergraduate, postgraduate and research students.
