Effects of Benadryl on chloroplast bleaching in Euglena gracilis

Abstract

Benadryl was used to temporarily bleach the chloroplast of the Euglena gracilis at varying concentrations of low concentration, high concentration, and no Benadryl. Three trials of Euglena were left in mediums with different concentrations and incubated for 24 hours. After 24 hours, the cells were fixed and the number of bleached chloroplasts were counted using 40x and 100x microscopy. It was found that a higher concentration of Benadryl will result in a higher number of bleach chloroplasts, while the control group did not show any bleaching. Using ANOVA and Post Hoc Tukey test to analyze the data, the p-value was less than 0.0001 and the results are significant.
