Transpiration Experiment
Measuring Water Uptake Using a Potometer
Observe how different environmental conditions affect the rate of transpiration in plants. The potometer measures water uptake, which correlates with transpiration rate.

Time: 0:00
Water Uptake
0.0 ml
Transpiration Rate
0.00 ml/min
Stomatal Activity
Low
Observation:
The experiment will show how environmental factors affect water movement through the plant. Watch the water level drop in the potometer as transpiration occurs.
Transpiration Process
1. Water Uptake:
Roots absorb water from soil, which moves up through xylem vessels to replace water lost through stomata.
2. Stomatal Regulation:
Guard cells control stomatal openings to balance gas exchange with water conservation.
3. Environmental Factors:
Light, temperature, humidity, and wind all affect transpiration rate by influencing stomatal opening and evaporation rate.
