Investigating Transpiration Rate
Using a piece of equipment called a potometer, we can measure how fast a plant loses water.
How would you simulate a "windy" day in this practical?
What is Investigating Transpiration Rate?
"A potometer is a device used to estimate the rate of transpiration by measuring the water uptake of a plant."
Which term correctly completes this GCSE Biology equation or calculation statement? A ____ is the total of results ÷ number of results
Which term correctly completes this GCSE Biology equation or calculation statement? ____ change = (final − initial) ÷ initial × 100
Choose the correct option to complete the statement. Biuret test turns ____ if protein is present
Which answer best completes the statement? Control variables are kept the same for a ____ test
Using a Potometer
As the leaf loses water, the air bubble moves along the tube.
Distance moved per minute = rate of transpiration.
Change environmental factors (light, heat, wind) to see the effect.
The potometer actually measures water uptake, but this is used as a proxy for water loss.
