The Effects of Wavelength on the Growth of Licmophora abbreviata

Abstract

The aim of this experiment was to investigate the effects of differing light wavelengths on the growth of Licmophora abbreviata. The experiment was conducted by growing 4 identical populations of the organism in separate test tubes; 3 of these populations had their test tubes covered by filters that restricted available wavelengths of light. Over a period of two and a half weeks, samples were taken from each test tube five times, and the number of cells were counted under a hemocytometer in order to track population growth. The results indicated that there was no significant difference between the growth rates under different wavelengths.
