Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light's colour is determined by its wavelength of light, and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these …showed first 75 words of 2044 total…

Then a comparison can be made between the similarities of aquatic photosynthesis and growth to that of terrestrial plants. Other follow-up experiments that can be done are to test other colours instead of the ones in this experiment like black lights and UV lights and light intensities of a wider range or an experiment to test the effect of temperature variations on the elodea plants.
