Cells, tissues, and organs: the architecture of plants; The plant cell building blocks: lipids, proteins, and carbohydrates; Lipids are a class of molecules that includes fats, oils, sterols, and pigments; Proteins playa central role in the biochemistry of cells and are responsible for virtually all the properties of life as we know it; Carbohydrates are the most abundant class of biological molecules; Biological membranes; The membrane lipid forms a bilayer, a highly fluid but very stable structure; Membranes contain significantamounts of protein; Cellular organelles; Most mature plant cells contain a large, central vacuole; The nucleus is the information center of the cell; The endoplasmic reticulum and golgi apparatus are centers of membrane biosynthesis and secretory activities; The mitochondrion is the principal site of cellular respiration; Plastids are a family of organelles with a variety of functions; Microbodies are metabolically very active; Cytoskeleton the extracellular matrix; The primary cell wall is a flexible n etwork of cellulose microfibrils and cross-linking glycans; The cellulose-glycan lattice is embedded in a matrix of pectin and protein; Cellulose microfibrils are assembled at the plasma membrane as they are extruded into the cell wall; The secondary cell wall is deposited on the inside of the primary wall in maturing cells; Plasmadesmata are cytoplasmic channels extend through the wall to connect the protoplasts of adjacent cells; Tissues and organs; Tissues are groups of cells that form organized, functional unit; Meristems are regions of perpetually dividing cells; Parenchyma is the most abundant living tissue in plants; Supporting tissues are distributed throughout the primary and secondary plant bodies; Vascular tissues are the principal conducting tissues for water and nutrients ; Epidermis is a superficial tissue that f orms a continuous layer over the surface of the primary; Plant body; Plant organs; Roots anchor the plant and absorb water and minerais from the soil.

This edition provides a comprehensive overview of the rapidly advancing field of plant physiology, supplemented with experimental exercises.

The general physiology of the plant cell. Metabolism. The physiology of development. Irritability and movement.

The book principles of plant physiology will be found particularly useful to University students reading for pass or honours degrees. For the benefit of the latter and of others who desire to read further on the subjects dealt with, references to monographs on the respective subjects are given at the ends of some of the chapters. In addition a bibliography is appended of works cited in the text. It is hoped this will be found useful to those students who wish to obtain detailed information from the original sources.

In its 19th edition, the book continues to provide a comprehensive coverage on the basic principles of plant physiology. It focuses on the concepts of plant physiological form & functions as well as processes in crop production. Besides fulfilling the needs of undergraduate students, this book will be useful to postgraduate students and also to those appearing in various competitive examinations.
