Plant cell biology studies plant cell structures and their functions. It concentrates on the metabolic and physiological processes that occur within the plant cell at the molecular and microscopic level. Plant cells can be classified into parenchyma cells and collenchyma cells. Plant cell biology is especially important in the genetic modification of crops. This book aims to shed light on some of the unexplored aspects of plant cell biology and the recent researches in this field. It aims to equip students and experts with the advanced topics and upcoming concepts in this area.
