The Effect of Light Wavelength on the Oxygen Production of Chlamydomonas reinhardtii

Abstract

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.
