Transpiration rate is the speed at which plants lose water through their leaves. It’s influenced by factors like temperature, humidity, and light. To measure it, you can record the initial and final weights of a plant and calculate the water loss over a specified time. Transpiration rate is typically expressed in grams of water lost per minute (g/min).

|---|---|---|---|---|---|
| Experiment 1 | 0 | 10.0 | 10.0 | 0.0 | 0.0 |
| Experiment 1 | 15 | 10.0 | 9.8 | 0.2 | 0.0133 |
| Experiment 1 | 30 | 10.0 | 9.6 | 0.4 | 0.0267 |
| Experiment 2 | 0 | 12.0 | 12.0 | 0.0 | 0.0 |
| Experiment 2 | 15 | 12.0 | 11.8 | 0.2 | 0.0133 |
| Experiment 2 | 30 | 12.0 | 11.6 | 0.4 | 0.0267 |
In this table:
- “Experiment” refers to the specific test or condition under which transpiration is measured. You can have multiple experiments to compare different variables like light intensity, temperature, or humidity.
- “Time (minutes)” indicates the duration of the experiment. You can record the time at which measurements were taken.
- “Initial Weight (g)” is the weight of the plant at the beginning of the experiment.
- “Final Weight (g)” is the weight of the plant at the end of the experiment.
- “Water Loss (g)” is the difference between the initial and final weights, representing the amount of water lost due to transpiration.
- “Transpiration Rate (g/min)” is the calculated rate at which water is lost by the plant per minute. It’s calculated by dividing the water loss by the time.
You can add more experiments or conditions as needed, and make sure to keep the units consistent (e.g., grams for weight and minutes for time). This table can help you analyze and compare transpiration rates under different circumstances or with different plants.
FAQs
