9.1 Measurement of Transpiration Rates using a Potometer (Practical 7)

Instructional video demonstrating how to measure transpiration rates of a plant using a potometer (Including how to set up the potometer, how the potometer works and how to take measurements to calculate rate) This is a required practical in the IB Biology syllabus (Practical 7) for Higher Level students only as part of Topic 9 Plant Science. You can be examined on your understanding of this practical in Part A of Paper 3 of the final IB exams.

Nice one comrade Pingu

Thanks, you helped me answer one of my questions for GCSE science homework, very helpful.

[@StephanieCastle]

Happy it helped!

[@venuraweeramanthree812]

thank you! this helped me to understand about the potemeter before going to the mock

[@lowballeddev]

does this work without an apple watch?

[@kanishkakaushik2356]

It will be more easy if you will use coloured water😁as it helps in marking the water level more easily and you can see it easily

[@jinoralphdarcega174]

nice, thanks

What was the plant they used? Also what is the ideal plant to use for checking rate of transpiration?

What would happen to the transpiration rate if the leaf was entirely immersed in water before mounting it on the potometer?

Do have a video about audus instrument, use to measure photosynthesis rate. If not please do it. If you have , can you send me the link. ❤️

awesome video but im using a different potometer!!!! dammit :(((

You need a Controll with no leafe attached, to see how much water evaporstes ot of the Pipette

You can use a variety of different leaves. Best if they have a relatively large surface area :)
