This experiment is based on the growth of the plant Portulaca Oleracea under the effect of different number of aspartame tablets added for watering. Aspartame is an artificial sweetening agent which gives the same taste of sugar both in a cheaper and effective way. To test the toxic effects of aspartame I have choosen the plant P. Oleracea as it grows easily in a short period of time and it is a eukaryotic organism like human beings. My research question is: “Does adding aspartame solution in different concentrations to a pot of P. Oleracea affects the rate of growth and health of the plant which are indicated by measuring the change in length and counting number of leaves respectively, within 20 days” In the experiment, I planted the P. Oleracea plants into five identical pots and watered each of them with different amounts of dissolved aspartame. I prepared the solution for watering under standard conditions and I also prepared 0.1M NaOH solution and added it to the main solution to stabilize the pH level to 7. In order to justify my results and see if they are valid or not, I used Anova Single Factor for analization. The P-value obtained from the lengths of the plants was 5.0469E-19 and 1.24E-14 for number of leaves which supports my hypothesis by being less than 0.05. This experiment showed that aspartame effects the growth and number of leaves of the plant in a negative way. So natural sweeteners should be used instead of the artificial sweetener aspartame, which gives harm to living eukaryotic cells.
