Cell Biology deals with the Cell structure. Cell biology is the science of studying how cells function such as their reproduction metabolism, and their internal and external anatomy. Biology means science of life. Cells are known as the basic building blocks of all livings things. Cell biology is a scientific discipline that studies cells-their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. This is done both on a microscopic and molecular level. Cell biology research encompasses both the great diversity of single-celled organisms like bacteria and protozoa, as well as the many specialized cells in multicellular organisms such as humans. Knowing the components of cells and how cells work is fundamental to all biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. This book introduces the general reader and the specialist to the study and analysis of cellular structure and function. This book reflects in par the recent resurgence of interest in the study of cell biology.
