What Is a Cell Biologist?
Cell Biology is a science that studies the structure, function, and various laws of life at the micro, sub-micro, and molecular levels. Cell biology is developed from Cytology, which is a study of cell structure and function (especially chromosomes). Modern cell biology studies the structure, function, and life activities of cells from different levels, such as the micro level, ultra-micro level, and molecular level. In the development plan of basic disciplines in China, cell biology, molecular biology, neurobiology and ecology are listed as the four basic disciplines of life science.

- Judging from the research content, the development of cell biology can be divided into three levels, namely: microscopic level, ultramicro level and molecular level. Viewed from the vertical axis of time, the history of cell biology can be roughly divided into four main stages:
- The first stage: from the late 16th century to the 1830s, was
- Late 19th century
- First, recognize the importance of the cell biology curriculum. Just as atoms are the smallest unit of physical properties, molecules are
- From 1839 MJ
- Cell biology makes extensive use of the achievements of adjacent disciplines in
- The study of cell biology is often happy to use cultured cells. Its advantage is that it can provide a sufficient amount of cells for biochemical analysis, and there is only one cell, the material is relatively single, and the analysis result is convenient. However, some aspects of research are inadequate, because cells in any organism are in a society, mixed with other cells to varying degrees, and cannot be adjacent to each other in their life activities. The effects of other cells, or even adjacent cells of the same type, are more complicated than those of cultured cells. Therefore, some problems are difficult to perform with cultured cells, or the results obtained can only partially reflect the actual situation. In order to study in a
