(618) 453-2469 Running Headline: Brassica rapa watered with energy drink with high amounts of caffeine Summary In this experiment it appeared obvious that the plant Wisconsin Rapid-Cycling (Brassica rapa) cannot inhibit proper growth from being watered with Rockstar energy drink versus normal H2O. The controlled plant grew perfectly fine with no stunted growth signs, discoloration, or abnormalities being watered with water. However the variable plant being watered with the energy drink called Rockstar, showed major differences. …show more content…
For humans caffeine is our go to drug for when we are trying to wake up in the morning with a cup of coffee, or even trying to stay late at work with an energy drink or even more coffee. Energy drinks have twice the amount and increasing of caffeine in them, which have neurological effects on humans (Persad et al., 2011). If the drink can cause neurological problems with humans it could be easily said there will be some sort of an effect with plants. After the experiment was complete it was easy to see that the hypothesis was correct, that the plants were unable to metabolize the energy drink. As to exactly why however I cannot say based on these results only. It could have been because the variables were soaking up the energy drink the whole two weeks, perhaps if they were to have been watered with the drink instead they would have been able to grow more after germination. The fact that the variable germinated at all was surprise. Roots are responsible for the vast majority of the water and nutrient supply for the plant (Burgess et al. 2004). Therefore since the variable plant was placed in the lid full of Rockstar, the soil was constantly soaking it in, the roots had no choice but to try and absorb the energy drink in plant of water and regular nutrients. Rockstar energy drink has barely any water it in compared to the amounts of caffine, sugars, and …show more content…
