Dry Ungerminated Peas Lab Report

In experiment one, involving the rate of respiration of germinated peas when exposed to a variety of different temperatures. From a general standpoint the data collected matched the hypothesis formed, as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may have been due to an improper seal on the oxygen sensor. Experiment two observing the respiration of dry ungerminated peas. Based on the class data collected it is clear the ungerminated peas consumed very little oxygen. The ungerminated peas require
less ATP therefore requiring less oxygen. Experiment 3 comparing how the rate of respiration is affected by the change in temperature. This data did not support our hypothesis, as the temperature increases the rate of respiration also increases. The randomness of the class data leads to a conclusion there was a variety of outside interferences that affected the outcome. For example group 3 may have had all worms die but one causing the oxygen consumed to be much lower and then spike for the next temperature. Another human error that may have had a negative affect on the date was improperly sealing the oxygen sensor. The final experiment compared a live seed to a dead seed in regards to the possibility of energy being released. The results show the live seed produced energy in the form of heat as it increased temperature by 15 degrees Celsius. The dead seed, as expected, did not increase in temperature, it remained the same.
