GCSE Biology - Transport in plants - Translocation (Phloem) and Transpiration (Xylem) #51
HTML-код
- Опубликовано: 8 фев 2025
- Learn how plants transport sugars via the phloem (translocation) and water via the xylem (transpiration) between the roots and leaves. We also cover the factors that affect the rate of transpiration: light intensity, temperature, humidity and air flow.

Are your videos for AQA?
@@user-qg4td6rg5x Yes they're mostly AQA I think but also relevant to other exam boards.
From their channel info: "Each video has been designed specifically for the 9-1 GCSE courses, and although they most closely mirror the AQA spec, everything you need to know for the main exam boards will be covered."
@@RevisionR Im doing eduqas will that still work aswell

i think this might be my favourite ever youtube channel (not for entertainment but for school lmao) but u get the point its amazing!
Thank you very much Little Mixer!! we really appreciate it 😊
Idk bro, this is pretty entertaining...
I agree
I’d say it’s pretty entertaining

thanks for the effort!
Thank you again, saw you comment all over their videos yesterday
thank you for making these questions. Appreciate the effort :)
Thank you ❤
Thank youuuu! ♡
this is the first time ive properly understood the effect of air flow and humidity, and my test is tomorrow - thank you so much

hello! i would like to thank you, because i used your videos as well as freesciencelessons for my end of year exams and got two 9's and a 6. keep up the good work!
Hey Asian that's amazing mate well done! Hope you've been enjoying your summer?

Literally love this channel, all the information needed for exam prep is always mentioned, concepts are very well explained, and the illustrations are adorable. ( watching this for my exam, wish me good luck!)
I can finally understand leaves, thank you!
Me too
I just clocked how stupid the curriculum is

cramming in for my biology exam that’s in 2 hours
same 😭😭
Sameee
Same omg 😭
so happy that in less than 24 hours i wont have to do biology paper 1 topics again
Same man

Hi guys, I really appreciate this video and thank you for taking your time to create it, but I'm still not sure about the whole water gradient thing, if you are able to explain it, that would be really cool!
Hi Hans thanks for the comment! Understanding the water gradient bit will rely on you knowing about ‘osmosis’ - which is the rule that water particles will move from areas of higher concentration to areas of lower concentration. If you haven’t already, give our video on it a quick watch and then rewatch the bit about humidity/airflow. Hopefully the explanations will then make a bit more sense! 👍
This guy deserves a billion subs
Wow thank you so much-not only have you explained it in such a precise and understandable way but I love the artistic style of the video(makes it much more enjoyable)☺️
Ah Toni thanks so much, that’s so nice to hear that you’re getting good use out them, and really glad you like the artwork too! 🥳
I'm a highschool teacher and this was soo helpful for my class! Thank you!
I have my gcse's next year and your videos are so clear now im making notes for my mock paper 1's and I will keep those papers for gcse's. Your voice is so clear and the diagrams aswell.
Plants make their own sugars through photosynthesis.
Translocation is the movement of materials from leaves to other tissues throughout the plant. And its mainly achieved by flowing the cells which arranged ends to ends to form long columns that called float and tubes.
Transpiration involves loss of water vapour through the stomata of plants. All the water molecules is is being arranged into one long chain then every tongue of water evaporates from leaf out of the stomata, drags the rest of the chains up slightly pulling along another water molecule.
Full chapter plz include experiments related to transport in plants... Your explanation is most effective, precise and clear..
im glad I have you to learn from during the corona outbreak and not just textbooks
😂 I don’t 8 will have teachers
it's really helpful to me because I moved to UK from sri lanka. so it was really hard to understand those things suddenly but I really enjoying study science. Thank you for your hard work.
I can't believe your channel was hidden from me all along, this video is so helpful and I now enjoy Science classes cause I understand. New sub btw
WE ALL DOING EXAMS AND WE ALL FINNA PASS INSHA ALLAH WADI BOMBO
There is no need to attend biology lesson while this channel is present
So trueeeeè
Probably the most well explained video I could've found
I’ve got my exam on Tuesday for paper one so decided it would be a good idea to know this as it’s a weaker topic for me, just in case of a 6 marker 😫 honestly this account has saved my science so I appreciate it so much especially as my school decided to wait a month before the exam to move me down to combined science higher from triple! Thank you so much :)
me too!
sameeeeee
Congratulatinons for checking this out if you are doing higher seperate science. It came up.
@@_CertifiedHoodClassic WHAT!!! I didn’t see it in the exam 😭 which exam board do you do? Mines AQA!!!!
@@madeleinej6048 im aqa too. You might remember a sneaky hidden 2 marker about 2 differences between the trans's, but thats about it for this section. Many forgot this and didn't know in my school. I was one of them.
preparing for my biology paper 22 tomorrow and this was good
the sad thing about this is that i probably wont use this in my future but i have to study it just to do good in school lol
Should you want a career in medicine, then you would need to study biology, and this is a key part of it
unless you wanna be like a doctor or something which is what your parents probably want
Thanks man your video really helps me understand the material and actually condenses the overwhelming information in easy to understand points
Glad it helped! 😊
why is this channel so underrated? i wish i could go to every single human beings phone and subscribe to ur channel
Ah thank you so much Mahnoor, we really appreciate it 🤩
Can't thank you enough for the amazing videos u upload. They make everything written in textbooks make so much more sense!
stop scrolling through comments and get revising bro
I feel called out🤣🤣🤣😅
Damn ok

Got some day-before-the-exam studying here lol, thanks for helping me quickly revise the syllabus (:
I really loved this video so much 😊😊😊🎉
You and freesciencelessons are the goats , thank you honestly , I have my gcse mocks in January and I really want to get 3 9s in science and this really helps, howver i do stuggle a lot with the concept of plant tissue, guard cells stomata all the mesophyll too , if there is a video for this please do recommend , ps i subbed
Thank you Barry! Best of luck with your gcses 🤞

i'm really hoping these videos help boost my grade. I'm barely passing and I only have 5 weeks to turn my grade around or I won't be able to get into the school I want to get into.
good luck m8

Thank you it helped me a lot. May God bless you.
perfect video, retained and gained knowledge top man definetly subbed!
How do the pores in Phloem help the cell sap to flow. Wouldn't it slow it down instead?
The pores allow organic nutrients to pass along the sieve tube from one cell to another . Basically more efficency in transport of organic nutrients like cell sap
Great video
very clear and concise
love it!!!
We are watching this video in class 8 informed by the teacher,if I the teachers never sent us videos so I guess I would never know cognito,very impressive explaination❤❤❤
Same literally
Frr
i have been watcing his vedios every day and its very helpufull
I LOVE you! Thank you soo much!
this video improved my understanding so much thank you!
Hi Luna! Thanks so much for taking the time you let us know - really makes a difference! Good luck :))

thank you ,its actually very good and very understandable ,thanks for this and appreciate your work
Thank you so much!!! This helped!!! Hats off to you!!!
This is a straight dub of a video
This is such a great video !!!! Thank you 😊!!!
very very helpful.
thanks so much for your drawings and illustrations!
Really happy to hear you found it useful!
Really helpful and brief explanation of things!!
absolutely spiffing!! Much enjoyed. Would definitely recommend to a friend or aquaintance. Rather blew my mind in fact !
We're very glad you enjoyed it A!! 🤩
Ah yes I’ve been watching this channels videos for a long time now because they’re really helpful to me and it teaches better than my bio, physics and chemistry teachers lol. I mean seriously, I don’t understand anything in school so I hop onto your channel and watch a video on it :D keep up the explanations!!
Cognito >>> Freesciencelessons
Thank u for explaining
Tomorrow is my semester exam and u saved my life🥺
this is an amazing video i love it
Could you please explain why it is important that dissolved sugars are moved both upwards and downwards in a plant?
This helped a lot thanks🤲🏼💯
Good luck on your exam everyone!!
Excellent explanation ,I alhumdulilah understood everything
such a good video!
Hey Binnie, thanks for taking the time to say so! Really lovely for us to hear :)
omg i love this explanation, thank you so much.
this video was really useful
Thank you so much ,it helps me a lot .
Night time, a tomato are closed so t can’t take place.
At higher temperatures, the (water) particles have more energy. This makes them more likely to evaporate
Air flow: the inside of the leaf has a much higher gr

Excellent explanation of transpiration. :)
Thankyou Glynis 😊
Correct me if I'm wrong but I was taught that The ph of the soil also affects transpiration rates
I understand it in a better way. From pakistan
explained very welll
thanks it helped me alot
you deserve 1000000000000000subs
should o go get food and revise until 11:30 or should i just sleeppp
Does more transpiration mean more photosynthesis?
it so over for me
SAMEEE😭😭
Me too bro😢
@@fathihangari5635my brother u have got 5 months ur good
do you need to know about the potometer experiment.
Yes
it is good for my students please send a link to download it.
Thank you for your effort in explaining these to us.As your title stated is about translocation and transpiration , I would wish to have more information about translocation which related with the phloem loading and phloem unloading stuff. And also I would really like to figure out the usage of sieve cells and companion cells too. Could anyone explain to me by replying my message maybe ?
Hi, that's usually more A-level type content so we don't cover it in these videos i'm afraid :(
@@Cognitoedu alright, understood. thanks
I’m primary five and this is honestly really good, easy to understand. Way better than my teacher’s explanation lol
Hi, can a transpiration pull occur even if the roots of the plant are not present?
i loveeee the handwriting
thank you so much!!! so helpful
You're welcome!
THANK YOU SO MUCH
Amazing explanation
really helpful thank you
Nice Explained
Best video. Subscribed and shared 😂😂
Thanks very much - really glad you found it useful :)
3:15 slayed
wait.. so whats transpiration again?
Hey Soqu, it's a bit of a vague term, but really it just means 'the evaporation of water from leaves' :)
Evaporation of water
Nice video Cognito
I am from India.
lovely
How are you so good at explaining
