Abstract:  Cell biology is a fundamental course of life science in university. With the recent rapid development of the theories in molecular biology and related technologies, the contents of cell biology have increased dramatically, such as the molecular mechanism and signaling pathways etc. This paper primarily dissected both the intrinsic and extrinsic influences on the cell biology teaching. The intrinsic means containing teachers accelerating the renewal of the knowledge system and improving their professionalism level are decisive for elevating the teaching effectiveness. Furthermore, the extrinsic measures including the utilization of a variety of teaching aids and the design of multiple types of homework and so on, which also play an important role in promoting teaching effectiveness. 

Key words: content of molecular mechanism, knowledge system, teaching aids, multiple types of homework, Cell Biology
