This was used for one of my lab videos (as we're learning plant physiology remotely). It was very interactive, fun, and easier to understand the concept of transpiration with the question each time you explained something! Well done!!!
Actual life saver, I knew there were going to be diagrams and questions of potometers in my upcoming test but I never really understood how it worked. Thank you so much for this video!

question: how is the air bubble formed in the capillary tube? that's the only thing I don't get is how to set up the air bubble in the graduated capillary tube..
How will : 1. Blowing dry air over the leafy shoot 2. Blowing moist air very slowly over the leafy shoot 3. Reducing the leaves on the shoot 4. Wetting the leaves - affect the movement of the air bubble per unit time??? Plz answer me🥹🥹
1. Dry air decreases humidity around the plant creating a high concentration gradient. It is easier for gas to pass out the stomata because of this so this increases transpiration.
4. Wetting the leaves creates a low concentration gradient meaning that water in the mesophyll layer will find it more difficult to leave the leaf through the stomata because there is more water outside than inside.

You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so. It does not form while the investigation begins.
You don't need to know - you only need to take into account that an air bubble is introduced. However, if you are still interested - You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so. Hope that helps 😁

bro same
Clearly explained....All the doubts clear...Very helpful...thank you very much😊😃
Thanks I’m having a test tomorrow and this sure helped me, will be coming back to see more videos and I’ll tell you if i got a 9❤️
Get that 9 Reem!
wait I need to know
i really hope you did!
What u got
defo failed or disappointed with result
Never knew I needed to know this until I did a past paper today and was so confused! Just in time for my exam on Tuesday thanks
Hope it went well!
Thanks, i wasnt taught this at school and i got my gcse for biology this morning so this really helped! Wish me luck
One of the best videos which cleared up my confusion in this experiment
Well done 👍👍❤❤

Wow both biology and physics teach us the different ways we can use a patometer, thank you
Wow !!! I really love the way this guy explains , it's so short , easy and simple . Will be coming here for more of my studies !!
Loved this video, this was very much needed
Hope you pass your exams.
Very good explanation:)
Finally found a video that is useful
Thank you for that
Glad it helped and you are very welcome 👍 visit kayscience.com for all of our videos and quizzes to help you with your revision 🔥
This video is really helpful. Thank you 👍😊
What are the precautions and their reasons plzz
question: how is the air bubble formed in the capillary tube? that's the only thing I don't get is how to set up the air bubble in the graduated capillary tube..
The air bubble is actually inserted inside the capillary tube
why is it a narrow tubing?
Thank your for the video and i got all my answer correct .i undertood well. Keep it up and uplode more videos.
This is very fun and very easy to understand. 🤩AWESOME video, thank you :D
How are we supposed to see all the text at the end with all the pop-up windows all over the shop?
thank you this is so helpful!
So happy this video has helped you! Check out kayscience.com for 1000s of FREE quiz questions 🔥
How does the bubble get there in the first place?
You have to "introduce" one somehow. You don't need to really know how; you just gotta accept the fact that there is now a bubble.
You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so.
Heyyyyy this diagram is incomplete there is a reservoir of air in this apparatus through which air is passed and bubble is introduced😊😊😊😊😊
wht are the dependent independent and control variables in tis experiment?please
brilliant and clear
Thank you!
How will :
1. Blowing dry air over the leafy shoot
2. Blowing moist air very slowly over the leafy shoot
3. Reducing the leaves on the shoot
4. Wetting the leaves
- affect the movement of the air bubble per unit time???
Plz answer me🥹🥹
1. Dry air decreases humidity around the plant creating a high concentration gradient. It is easier for gas to pass out the stomata because of this so this increases transpiration.
2. Blowing moist air will decrease transpiration for the opposite argument of what I said in 1.
3. Reducing the leaves reduces the amount of stomata available so less water is lost through transpiration
4. Wetting the leaves creates a low concentration gradient meaning that water in the mesophyll layer will find it more difficult to leave the leaf through the stomata because there is more water outside than inside.
such a well done video omg
Thank you so much!
You're welcome! thank yoooou tell your friends about us!
Hey I have a question that I hope anyone could clarify for me, why is there an air bubble in the capillary tube, like how did it form there?
Did you find your answer
You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so.
However, you don't need to know this - you only need to take into account that an air bubble is introduced - Hope this helps 😁
Was kinda helpful for a GCSE student but in Kenya, Africa its KCSE😢😢
can I calculate Transpiration rate having input data Leaf RH, Leaf Temp, PAR and Stomatal conductance
Great stuff!
Thank you sir. It helped my understanding about potometer and my biology task.

@@KayScience Yes please!
Thank you!
Great video.
Question- How is an air bubble introduced to the potometer?
It forms while the investigation begins.
You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so. It does not form while the investigation begins.
Thank You ! 👍
Do we need to know where the air bubble comes from? Just one bubble?
You don't need to know - you only need to take into account that an air bubble is introduced. However, if you are still interested - You have to tip the capillary tube for a few seconds and the place it back into the beaker of water then an air bubble will form after a while or so. Hope that helps 😁

Thanks
what a legend
thank you
Good luck in your exams y'all
I concur
👍
doing gods work niga
kindly remove popups at the end
I love u boo
The fact that heade an air bubble red makes me think of red sus. Also thank you for the video
