Results: Table 1 shows the results of open stomata between plants exposed to the light and plants kept in the dark. The number of open stomata for plants kept in the dark was significantly high at an average of 80.33. As time progressed, the number of open stomata decreased to an average of 20. On average, the number of open stomata for dark plants was 46.76. The number of open stomata for plants kept in the light was different from that of the open stomata for plants kept in the dark. At first the average number of open stomata for plants kept in the light was at 56.67. As time went on, the average number of open stomata stayed between 50 and 60. The lowest count was measured at the 45 minute mark with 48.33 average number of open stomata. Overall the average number of open stomata in plants kept in the light was 60.29.

Looking at our data, we can’t have confidence in our means for the data from plants kept in the dark. Our standard error value was rather high at 8.89 and the error bars were large. For the plants that were kept in the light, we can have confidence in our means because the error bars were rather small. In addition, the standard error value was small and it was 3.11. There is no statistical difference in the means either since the error bars overlap. Table 2 shows the results for open stomata between plants that were covered with foil and plants that were not covered with foil. For plants that were covered with foil, number of stomata started out high at 78.67 but dropped all the way to 41 by the end of our experiment. The average number of open stomata throughout the entire experiment was 56.61. In comparison to the plants that were covered, the uncovered plants had rather consistent values. The number of open stomata stayed in the 50 to 60 range with the highest value being recorded at 66.67.
