Plant cell biology is a natural science which studies the physical structure as well as the chemical and physiological processes related to plants at the cellular level. Plant cells are eukaryotic cells which are found in the photosynthetic eukaryotes of the Plantae kingdom. Some of their distinctive features are the presence of a cellulosic cell wall, capability to store starch, presence of plastids and ability to perform photosynthesis. Plant cells and tissues can be majorly classified into parenchyma cells, collenchyma cells, sclerenchyma cells, xylem, phloem and epidermis. This book presents this complex subject in the most comprehensible and easy to understand language. It aims to shed light on some of the fundamental concepts of plant cell biology. This book will serve as a valuable source of information for those interested in this field.
