Introduction: The objective of this experiment was to determine the effect different levels of ph would have on the dictyostelium purpureum.

(Lebraud 2003) When food is available for the Dicty it will multiply in a unicellular microorganism, however as the food is depleted the dicty will develop during the starvation. (Lebraud 2003) The development occurs at different stages; first the cells will differentiate from one another, followed by the formation of a slug, then fruiting bodies will sprout spores. (Lebraud 2003) The food source provided in this experiment was e. coli plated in a Petri dish. Five plates were used to test the different ph levels. Two plates were used to test for acidic
