The adhesion and cohesion of water is something very important to life. It is these properties that allow the movement of water against gravity. Without these traits, water could not be used to sustain life.
Question: What factors affect transpiration?
Hypothesis: Factors that increase evaporation will increase transpiration.
Prediction: Light and wind will have the highest rate of transpiration.
Methods: There were not details modified in the lab manual.
Results: The results that we got back were very interesting. All of the data was not significant from each other, so the factors in our lab did not affect transpiration. There were no obvious mess ups in the lab. Every step went pretty smoothly, however the results contradict the literature.
Discussion:
Control:
We have a control due to the fact we need something to compare to. …show more content…
This should increase transpiration since the extra light would increase evaporation. Our results were actually not significant compared to the control, so the rate of transpiration was unaffected by light. The rate of transpiration due to light is -0.1413 with a standard deviation of 0.018. This average was slower than the control, but not statistically significant due to the standard deviation overlap. This is different than the known literature. For example, farmers often see an increase of rate in transpiration during the day. This is not only because of the increasing rate of evaporation due to visible light radiation, but also because it acts as a stimulus to the plant in question. Light stimulated the opening of the stomata on
