Introduction: The ultimate goal of this laboratory experiment was to have a better understanding of phagocytosis and how certain factors may affect the rate of phagocytosis. The first part of the experiment was to test the effects of both concentrations of India ink, and feeding status on the rate of phagocytosis. Through this testing one can identify the conditions necessary to obtain the highest rate of phagocytosis. The second part of this lab was taking the variables that maximize the rate of phagocytosis (which we found in the first part of this experiment), and adding different chemical and environmental factors to see their effect on phagocytosis. Phagocytosis is an extremely important apparatus used by many organisms. Protozoans use phagocytosis to engulf food and kill bacteria, but also our own bodies use phagocytosis to destroy foreign particles. This process can be seen in the human immune system. Phagocytosis is activated when an immune cell is turned on by an attachment to pathogen-associated molecular pattern or some cells can recognize foreign particles (Roles of Phagocytosis). The dendritic cells destroy the foreign cell to create antigens. (Roles of Phagocytosis). If macrophages find these foreign they destroy the foreign cell using phagocytosis (Roles of Phagocytosis). The organism that was experimented with was tetrahymena. Tetrahymenas are freshwater ciliated protozoan and are the ideal candidates for the study of cells for students (Bozzone 1).…
