Traspiration Lab 9
1. For this experiment, what were the independent variable and the dependent variable?
What were the constants?
The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light, fan, dark, and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used, room temperature, type of scale used and how far the fan/light was placed from the plant.
2. Calculate the average rate of water loss per day for each of the treatments. (Humidity,
Light, Fan, Dark, Room or control).
Humidity | 21.63 |
Specific Light | 21.63 |
Dark | 5.03 |
Control | 5.33 |
3. Explain why each of the conditions causes an increase or decrease in transpiration compared with the control.
The plant placed under the light was the environmental factor that had the highest average rate of water loss per day because the heat from the light sped up transpiration. In the humidity there was little transpiration lost because the saturated wet atmosphere decreased the amount of water lost. The dark condition had the lowest average water loss per day because transpiration requires some type of starter source (like light or wind) for water to travel from the roots of the plant to the stomata of the leafs.
