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!
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!!!
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!
Clearly explained....All the doubts clear...Very helpful...thank you very much😊😃
Thanks, i wasnt taught this at school and i got my gcse for biology this morning so this really helped! Wish me luck
Wow both biology and physics teach us the different ways we can use a patometer, thank you
One of the best videos which cleared up my confusion in this experiment
Well done 👍👍❤❤
Thank you Kay Science! These videos go above and beyond!

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 !!
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 🔥
what a legend
Loved this video, this was very much needed
Hope you pass your exams.
Very good explanation:)
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?
This video is really helpful. Thank you 👍😊
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.
How are we supposed to see all the text at the end with all the pop-up windows all over the shop?
What are the precautions and their reasons plzz
Thank you sir. It helped my understanding about potometer and my biology task.

@@KayScience Yes please!
Was kinda helpful for a GCSE student but in Kenya, Africa its KCSE😢😢
brilliant and clear
Thank you!
Thanks
Thank your for the video and i got all my answer correct .i undertood well. Keep it up and uplode more videos.
such a well done video omg
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 😁
thank you this is so helpful!
So happy this video has helped you! Check out kayscience.com for 1000s of FREE quiz questions 🔥
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.
This is very fun and very easy to understand. 🤩AWESOME video, thank you :D
Thankyou!
Thank you so much!
You're welcome! thank yoooou tell your friends about us!
Have a prac tomorrow ahhhh hope I pass
I hope so too!

Great stuff!
can I calculate Transpiration rate having input data Leaf RH, Leaf Temp, PAR and Stomatal conductance
Thank You ! 👍
wht are the dependent independent and control variables in tis experiment?please
Thanks!
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 😁
👍
I love u boo
Good luck in your exams y'all
I concur
doing gods work niga
kindly remove popups at the end
The fact that heade an air bubble red makes me think of red sus. Also thank you for the video
