i think this might be my favourite ever youtube channel (not for entertainment but for school lmao) but u get the point its amazing!

so happy that in less than 24 hours i wont have to do biology paper 1 topics again

cramming in for my biology exam that’s in 2 hours

this is the first time ive properly understood the effect of air flow and humidity, and my test is tomorrow - thank you so much

The four factors affecting the rate of transpiration: Temperature Light Intensity Air Flow Humidity

Post-Video Quiz: 1. What are translocation and transpiration? (0:08) 2. What is the phloem and what are its functions? (0:30) 3. What is the xylem and what are its functions? (1:22) 4. What does lignin do? (1:37) 5. What are the four main factors that affect the rate of transpiration? (2:52)

I can finally understand leaves, thank you!

stop scrolling through comments and get revising bro

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)☺️

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!

Can't thank you enough for the amazing videos u upload. They make everything written in textbooks make so much more sense!

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.

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.

Probably the most well explained video I could've found

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!

Full chapter plz include experiments related to transport in plants... Your explanation is most effective, precise and clear..

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'm a highschool teacher and this was soo helpful for my class! Thank you!

perfect video, retained and gained knowledge top man definetly subbed!

Ive got Bio p1 tommorow A MASSIVE THANK YOU

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

Thanks man your video really helps me understand the material and actually condenses the overwhelming information in easy to understand points

im glad I have you to learn from during the corona outbreak and not just textbooks

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

There is no need to attend biology lesson while this channel is present

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.

Thank you so much!!! This helped!!! Hats off to you!!!

Great video very clear and concise love it!!!

This is such a great video !!!! Thank you 😊!!!

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 :)

Really helpful and brief explanation of things!!

This helped a lot thanks🤲🏼💯

Thank you it helped me a lot. May God bless you.

god bless you sir i would literally fail without these videos.

thank you ,its actually very good and very understandable ,thanks for this and appreciate your work

Got some day-before-the-exam studying here lol, thanks for helping me quickly revise the syllabus (:

How do the pores in Phloem help the cell sap to flow. Wouldn't it slow it down instead?

Excellent explanation ,I alhumdulilah understood everything

omg i love this explanation, thank you so much.

Hi, can a transpiration pull occur even if the roots of the plant are not present?

Thank you so much ,it helps me a lot .

very very helpful. thanks so much for your drawings and illustrations!

I LOVE you! Thank you soo much!

Good luck on your exam everyone!!

Could you please explain why it is important that dissolved sugars are moved both upwards and downwards in a plant?

WE ALL DOING EXAMS AND WE ALL FINNA PASS INSHA ALLAH WADI BOMBO

this is an amazing video i love it

this video improved my understanding so much thank you!

i have been watcing his vedios every day and its very helpufull

it so over for me

I really loved this video so much 😊😊😊🎉

why is this channel so underrated? i wish i could go to every single human beings phone and subscribe to ur channel

this video was really useful

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

thanks it helped me alot

Nice video finally my concepts are ckear

Thank u for explaining Tomorrow is my semester exam and u saved my life🥺

Amazing explanation

I understand it in a better way. From pakistan

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.

Great work

thank you so much!!! so helpful

such a good video!

thank you so much!

Thank you thank you thank you!

THANK YOU SO MUCH

Excellent explanation of transpiration. :)

This is a straight dub of a video

legend

Nice video Cognito

Good video !!

I’m primary five and this is honestly really good, easy to understand. Way better than my teacher’s explanation lol

How are you so good at explaining

i loveeee the handwriting

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

Thank You!

thank you !

Nice Explained

Does more transpiration mean more photosynthesis?

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 ?

you deserve 1000000000000000subs

it is good for my students please send a link to download it.

absolutely spiffing!! Much enjoyed. Would definitely recommend to a friend or aquaintance. Rather blew my mind in fact !

Correct me if I'm wrong but I was taught that The ph of the soil also affects transpiration rates

Best video. Subscribed and shared 😂😂

i am subing great channel

do you need to know about the potometer experiment.

Cognito >>> Freesciencelessons

soo goood

I am from India.

3:15 slayed

👍👍👍

👏👏👏👏👏

wait.. so whats transpiration again?

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!!

❤💖

greaaaaaat

the xylem tubes look like something from star warrs

hi, thanks for the video, can you please explain to me the air flow on the rate of transpiration and the relatioship between air flow around the plant and transpiration rate? Thanks so much
