Cell biology is based on cells, from the overall level of cells, submicroscopic level, molecular level, etc. (Sino. A. - A11 - at the forefront of biomedicine) from a dynamic point of view, A discipline that studies the structure and function of cells and organelles, the life history of cells, and the laws of various life activities. Cell biology is one of the frontier branches of modern life sciences. It mainly studies the basic laws of cell life activities from different structural levels of cells. From the perspective of life structure, cell biology is located between molecular biology and developmental biology, and they are connected to each other and infiltrate each other.
Using the techniques of modern physics and chemistry and the methods and concepts of molecular biology to study the science of life activities at the cellular level, the core problem is the problem of inheritance and development.
