Quiz questions An experiment was done to see how the distance from a light source affected the rate of photosynthesis. Three aquatic plants were used: Elodea, Cabomba and Hornwort were used. The number of bubbles at each distance was counted. The experiment was done three times for each species. With each experiment the 10 cm distance was done first, then the 20 cm distance and so on. The plants were all bubbling at about the same rate before the experiment The following data was obtained: Mean number of bubbles produced over a 10 minute period Distance from the Elodea Cabomba Hornwort light source 0 100 120 10 cm 0 25 90 20 cm 0 11 60 30 cm 1 6 30 40 cm 0 4 0 50 cm What can be done to improve the table?
