As one of the primary sources of O2 in many freshwater ecosystems, Chlamydomonas reinhardtii have well-defined genetics for photosynthesis. We have examined more specifically the effect of various light wavelengths on C. reinhardtii and its development of O2 production for a more thorough perception of its photosynthetic selectivity. The method chosen used C. reinhardtii culture, which were subjected into 15 vials, where each 5 were separated under blue light, red light, and white light. Cell counts were measured using a haemocytometer, and average oxygen production for each treatment was then calculated. The average O2 production was found to be very significant for white light compared to blue and red light, however the average blue and red light O2 production values were insignificant based on the one-way ANOVA test and Tukey’s multiple comparison test.
