Cell Biology covers one of the most fundamental and elaborately studied areas of biology: the cell. The cell is the basic unit of life and has all the structural and functional properties required for life. The book has been divided into 20 chapters—beginning with the origin of biological systems and ending with tools for the study of cells. Every effort has been made to include the most recent information. Each chapter is provided with an adequate number of illustrations. This book can serve as a basic textbook for students of molecular biology, genetics, biochemistry, agriculture and biotechnology, or as a reference book for those interested in learning the fundamentals of cell biology, in particular, the origin, organization and functions of subcellular components and cell types.
