The null hypothesis for the experiment was that oxygen production is the same in both plants while the alternative hypothesis was that oxygen production and thus the rate of photosynthesis is higher in Ceratophyllum than in Cabomba due to its efficiency in carbon dioxide utilization (Kitaya, Murakami, & Takeuchi, 2003).
Materials and Methods
Experimental Design The research question to be answered in the experiment was whether there is rate difference, in oxygen production, in oxygen production between Ceratophyllum and Cabomba. It was predicted that each of the plants would have different oxygen production rates. The dependent variable was the rate in oxygen ...
