Students performed 10 light-chamber trials with leaves from each of the four plant species. The carbon dioxide concentration data was then used to calculate the maximum carbon dioxide exchange rate for each leaf.

Table 15.2 shows the calculated and mean carbon dioxide exchange rates for each of the four plant species.
