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.

i agree jeremy corbyn is a great person

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

[venuraweeramanthree]

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

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

Plot twist: This is actually an Apple watch ad directed towards schools.

[lowballeddev]

does this work without an apple watch?

[chiara]

May God bless you I finally understood this topic

[sksciencegampaha]

Thank you very much. Really very clear. I got it

[lobster]

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

[jinoralphdarcega]

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

[subratakumardas]

(Thanks and thanks )322x for the video

[dookz]

hey guys in my biology class that got told to watch this vid

[sksciencegampaha]

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. ❤️

[penypeniel]

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

[doga]

how would i know the difference between water produced by photosynthesis or transpiration pllsss help!

[classifikation]

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

[pactoomuchu]

1:48 there is literally air going in through the stomata of the leaf

[indoni.x]

Can someone give me a hypothesis for this ?😭I'm writing a test abt this tmr guyssss

[alhassanlol]

why at 4:04 she said to simulate still air can u explain ????

[rysmanurmallahidayat]

Why do plant stems have to be cut in water?
