Respiration In Seeds

Cellular Respiration in Seeds Cellular respiration is a chemical process the generated energy. In this experiment, seeds were tested to collect data relating to the cellular respiration process. In order for these seeds to start the cellular respiration process they need moisture or they need to be germinated. The purpose of the experiment is to test the CO2 and O2 levels given off by germinated seeds going through cellular respiration. However certain abiotic features can impact the cellular respiration process. The germination process was changed to answer the question: How does temperature impact cellular respiration? Specifically in this experiment the seeds were germinated in colder water to conclude how temperature changes impact …show more content…
In the control corn experiment the CO2 levels were slowly risings for about 500 seconds. However, there was a dramatic increase in the CO2 levels shortly after the 500 mark. There was also a dramatic fluctuation after the 500 second mark as well. At the start of the experiment the CO2 levels was around 900 CO2 ppm at zero seconds. At 600 seconds, the CO2 levels were around 2500 CO2 ppm making a 1,600 CO2 ppm change in CO2 levels. However for the O2 gas levels, it started out around 19.72% at the zero second mark. It they declined to 19.65% at the 600 second mark causing a 0.07% decrease. Overall, the CO2 levels increased and the O2 gas levels decreased in the corn control experiment. However, there were different results in the experimental corn test. The cold water had an affect on the CO2 and O2 levels. The CO2 levels started at about 920 CO2 ppm at the zero second mark. As time went on the CO2 levels began to fluctuate more than the control experiment. At the 600 seconds mark the levels were around 1100 CO2 ppm increasing by 180 CO2 ppm. At the same time, the O2 gas levels were being measure. At the zero second mark the O2 levels were around 19.53% and decreased as time went on. At the 600 second mark the O2 gas levels measured around 19.47% decreasing 0.07%. Overall, the CO2 levels increased and the O2 gas levels decreased. Overall, the CO2 levels …show more content…
The results from the experiment contradicts part of the hypothesis. In both experiments the O2 levels went down, but at a similar rate. However, the CO2 levels increased in both experiments, which goes against the idea that the CO2 levels would go down due to the cold water. However, the cold water did have an effect on the cellular respiration process. In the time the data was recorded, the CO2 levels in the experimental group did not increase as much as the control group. All the corn needed was to germinated, (moisture) and the nutrients it already had to go through cellular respiration similar to what was said on modernbio.com. Despite the fact the data contradicts the hypothesis, the results seem logical. The cold most likely does not stop the cellular respiration process, which was thought in the hypothesis, it more so slows down the process. This explanation is supported by the results from this experiment. Further testing could be done to get a wider range of knowledge on how temperatures impact the cellular respiration process. To take it a step further, other abiotic and biotic factors could be tested and researched to determine how they impact cellular respiration in seeds, or any living organism. By collecting, analyzing, and drawing conclusions from this experiment it can help more people understand how small factors can lead to even bigger
