Investigating phagocytosis in Tetrahymena
|
An Experimental System Suitable for Introductory & Advanced Instruction
Tetrahymena, a freshwater ciliated protozoan, is in many ways an ideal candidate for the study of cells by students. Readily obtained and cultured, Tetrahymena can be used to study ciliary motion, organelle structure and function, cell morphology, cell proliferation, and cell behaviors (Leick & Hellung-Larsen 1992; Wheatley et al. 1994). Because of the ease with which Tetrahymena can be grown and manipulated, it is especially suitable for use in inquiry-based labs and student projects.
