Introduction:
In this experiment we demonstrated how transpiration works. We took branches from the same plant and measured the transpiration rate of each branch in different environmental conditions. The conditions that we looked at included different temperatures and the amount of light. When we started the experiment we believed that the hot environment would have a higher transpiration rate than the rest of the environments because the heat would speed up the evaporation of water vapor. We also believed that by taking out half of the light it would decrease the rate of transpiration but not much because the temperature plays a vital role in transpiration rates. We also thought that when the temperature was at a moderate temperature, the plant would still transpire just not as much as the hot environment. Also, when the plant was at a cold temperature we thought that it would transpire very little. We thought the same results for the decreased light but, we thought that the overall transpiration rate would decrease all together but still keep the low and high variability with the different temperatures. The loss of water through evaporation from the plant surface is called transpiration (Brooker, 2008).
