Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose. Some organisms have only one cell, while others are organized into cooperative groups with huge numbers of cells. On the whole, cell biology focuses on the structure and function of a cell, from the most general properties shared by all cells, to the unique, highly intricate functions particular to specialized cells. The history of cell biology is rooted in the related sciences of biochemistry and molecular biology. Biochemistry grew from physiology and chemistry early in the twentieth century and gave fruit to molecular biology in mid-century. The study of the cell is done on a molecular level; however, most of the processes within the cell are made up of a mixture of small organic molecules, inorganic ions, hormones, and water. Approximately 75-85% of the cell’s volume is due to water making it an indispensable solvent as a result of its polarity and structure. This comprehensive book provides a complete, one-stop resource for students, researchers, and teaching faculty across the biological and medical sciences.
