Investigating the Effect of Starvation on Food Vacuole Formation in Tetrahymena pyriformis Introduction: This experiment was performed in order to observe the effect of starvation has on the rate of food vacuole formation in the protist Tetrahymena pyriformis. As the Tetrahymena gathers and ingests food, more food vacuoles form. The rate of food vacuole formation can be related to starvation in the sense that starvation either increases, decreases, or has no effect on the vacuole formation. From this information these predictions can be made: 1. If the cells are starved they will attempt to try and find food at a faster rate and thus the starved cells will have greater number of food vacuoles. 2. If the cells need more energy to produce food vacuoles, then the starved cells will have fewer food vacuoles. 3. If the formation of food vacuoles is independent of starvation then both types of cells should have equal number of food vacuoles. Materials and Methods:
