Xylem=water Phloem=food (sugar) *XY*lem=*W*ater *PH*loem=*F*ood You can remember which ones match up because XY and W are near the end of the alphabet. Also PH and F make the same noise.

I apologize that back then my level of English wasn’t that good. My first language is Spanish, today I see the mistake -which I won’t correct- and I hope you never struggle learning a foreign language. Peace!
Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures, such as tubers or bulbs
Thank you for making this video so engaging. I find biology to be interesting, but I dislike having to do all the paper work and having to study hard to understand it. Your videos make what I'm learning feel simple. :)
Wow these videos are incredible! They are being so much help. After studying a couple of hours it's so good to watch your videos and review concepts I might have not understood. Thank you thank you thank you! Please keep making these videos...
Just discovered Crash Course and I'm super excited. These videos seem like a great way for one to review and solidify concepts that one is trying to learn. Thanks for making it, it is a good thing.
A big shout out to Crash Course!! Hank has helped me with Bio since high school and now in college. Not only with science but with math, history, psychology and more! Thank you so much for breaking down information and going into more detail. Oh who doesn't love the little animation in the background.
Extra info that confuses you? What exam board are you on? I'm on Edexcel and this video doesn't even scratch how much more there is to it than this e.g. the cohesion-adhesion transpiration stream, translocationn etc
Last time I’ll ever watch a crash course vid as I have my final exam tomorrow. Just wanted to say thanks for helping me through my entire A level without you guys I would’ve definitely failed
This is awesomeness!! GREAT presentation, well-geared towards the 2-second attention span audience, fun visuals and silly accents... Absolutely brilliant. Gotta love the social and eco commentary slipped in there, too. YES! I wanna do this, too!
Crash course saved me all throughout high school, and even now in my second year of university it can still help clear stuff up in my intro classes! Thanks Crash Course!
CrashCourse helped me get through my undergrad. Revisiting much later, it's still highly relevant and a helpful refresher during my PhD studies! great work you guys!
Nick Spears 1. Describe how water travels from the to cell to the leaf. Map the way. Water is transported into the roots and enters the xylem. Cohesion and Adhesion cause the water to move through the xylem. It then goes from the xylem in to the mesophyll cells and evaporates through the stomata. 2. How is ground tissue different in the root/stem the the leaf? The ground tissues does not has chloroplast cells/mesophyll cells and does not preform photosynthesis. 3. Describe how the stomata opens and closes. The stomata open due to the guard cells expanding and contracting. The cells expand because of water/turgur pressure. When more pressure is present the cells expand and when there is less pressure they contract and let the stomata open.
You have no clue how grateful I am for these videos they help me to understand bio from a different voice and you're so entertaining as well. Thank you Hank :")
I would just like to point out that in his second biology video he correctly points out that metric is used by scientists and "parts of the world where things make sense" throwing that out there at anyone still arguing which is better because honestly he is totally right.
I really wish Crash Course and Sci show had existed while I was in High school. I think I would have done alot better in my classes if it did. I find it funny that I'm a 23 year old who has a notebook full of notes and quotes from these shows more then I ever did back in school. Makes me want to buckle down and go to collage. so thank you so much John and Hank for making me remember that learning is fun.
the plant you are holding in the beginning is not yarrow, but the artwork on the title page is yarrow aka achillea millefolia. If you compare the two, you can see some differences. Even though the camera work on the plant is blurry, it can be seen clearly enough to tell.
I love watching these episodes. Just started college and need all the educational help available. Not sure how we went from plants to the metric system on the comments but if your an American supporting the metric system you apparently did not grow up working on cars. It may be hard to understand but mechanics are proud of their standard system.
They teach this stuff to us in our seniour year. (Yup, I mean in highschool). I have been trying to find a decent vid on the subject but I couldn't find it in my language which is Turkish. This vid just saved my life for real. The final exam, here I come! Thank you for the vid!
As a Indian supporting a Norwegian supporting an American supporting an American supporting the metric system, I hope Crash Course does start using it, as well as the rest of the nation but I'll take what I can get. Start the chain!!!
Thank you so much I feel to have been Blessed beyond measure to have found someone who makes science so simple as you do..... May God Bless you more for your tutoring....
Aaaaaaaactually, that redwood is only the TALLEST organism in the world! The largest one is a honey fungus in Oregon, which measures around 2.4 miles! :D the more you know!
Crash Course team you have taken my most hated part of Biology and actually made me understand it. Sadly 10 years after I left high school with that big ugly C on my final results paper, but better late than never. Thank you!
Oh I believe this is an unanswered question on Ve's channel, how water is transported up by plants. Thanks Crashcourse for explaining to us and in great detail too.
As an American supporting an American supporting the metric system, I hope Crash Course does start using it, as well as the rest of the nation but I'll take what I can get.
I remember learning this stuff in Highschool. (It feels so long ago). I wish Hank had been my teacher. Even though it was my favorite subject my Bio teacher was as interesting as a rock.
Xylem=water
Phloem=food (sugar)
*XY*lem=*W*ater
*PH*loem=*F*ood
You can remember which ones match up because XY and W are near the end of the alphabet. Also PH and F make the same noise.
Thnx! But I think xy makes the z sound. Like, zylem
kavya das Ya but I meant they are all near the end of the alphabet
+Ginger Ruparts When you're trying to remember and relate words, its what you feel that matters, not the technical stuff. (This is my opinion, just saying how my brain works)
XY and W make me think of chromosomes!
Or the "ph" in phloem sounds like "f" which is also there in *F* ood
As a teacher, I gotta say I highly recommend this videos! They're very illustrative and clear for pupils, plus the engagement they generate :D
are you sure you're a teacher; "this videos"?
English might not be his first language
7:10 :p
I apologize that back then my level of English wasn’t that good. My first language is Spanish, today I see the mistake -which I won’t correct- and I hope you never struggle learning a foreign language. Peace!
Hank: And the oldest living thing-
Me: The fish?
Hank: A patch of sea grass.
I thought that too XD
The 45 dislikes are from the nonvascular plants.

_Stop scrolling and concentrate on what Hank's sayin'!!_

Uh the adds were on..... but thx for reminding me
OKAY. So damn bossy. :(
Same thing as Peter salucci
no

I love how the bass in the seagrass photo is like "yeah I photo bombed whatcha gonna do about it?"

My teacher made a quiz on your video. Be proud.
+Kafi Shabbir lol my bio teacher plays this in her lesson after teaching as a kind of summary
my teacher sucks just saying your lucky
PJ Tice nice
A teacher knows a good resource when they see one ;)
Me too
As a horticulture major, it makes me happy when videos like this make it easy to learn about plants and how they work :)
I really like this setting - it’s so calming and lovely and makes me appreciate what you’re teaching more.
6:34 - 7:10 - One of the most interesting & revealing things I've ever heard on Crash Course Biology. Awesome, thank you
My exams ended today. I'm just here to be entertained by the pure cleverness of this video 👌
good for you hell is ending for me tomorrow
these videos are the reason I'm passing my biology class
I'm a biology major ...and these videos are the reason why I actually know what I'm studying and get to pass my classes
Same here! 🌱
Indeed !
Same here
Thank you for making this video so engaging. I find biology to be interesting, but I dislike having to do all the paper work and having to study hard to understand it. Your videos make what I'm learning feel simple. :)
Why isn't biology fun like this anywhere else?
Because schools aren't good at their job.
IKR
I Agree with you KingOfEverything
There’s only one hank..
@@Teawithlee for the longest time, i thought there was only one green guy. I didn't know a hank green even existed
Corona got me wishing I was outside with him, instead I'm inside listening to him for a project...
Cant thank you enough Hank! You actually make studying for Bio not only interesting but actually entertaining. That's a scientific breakthrough man!
Wow these videos are incredible! They are being so much help. After studying a couple of hours it's so good to watch your videos and review concepts I might have not understood. Thank you thank you thank you! Please keep making these videos...

Can I PLEASE borrow your brain just for two hours tomorrow? :'( HUHUHUHU
December tests? Me too, me too.
Idk can you borrow his brain ? (It's MAY I not CAN I)
i think can I works also?
Janelle Margallo I hate tests for science and biology
Janelle Margallo lol
Thank you so much! This helped me categorize everything instead of being lost with all these new terms.
A big shout out to Crash Course!! Hank has helped me with Bio since high school and now in college. Not only with science but with math, history, psychology and more! Thank you so much for breaking down information and going into more detail. Oh who doesn't love the little animation in the background.
Oh gosh... my AP final is tomorrow! Crash course is literally my study regiment.
Crash course is my life line through A level Biology 😂
+Aiden Brealey tell me about it! I hope this sticks till exams next month tho xD
it has alot of extra info which confuses me, i am doing AS
Mareena Khan All the best!! What exam board are u on?
+Mareena Khan can you make the vedio of phloem

I'm not kidding when I say this channel literally saves my high school career.
Actually love how you talk fast btw, cause aint nobody have time for a droning voice.
The only TH-cam videos I don't speed up!
I love all the comments from students! I use these in my intro biology course, because I'm pretty sure it makes more sense than I do!
THIS CHANNEL IS A TREASURE
my paper 2 AS biology exam is in 14 and a half hours, this is helping me so much
you have just taught me more in 12 minutes than my teacher has in 2 years....
thank you for existing!!
Crash course saved me all throughout high school, and even now in my second year of university it can still help clear stuff up in my intro classes! Thanks Crash Course!
As a botanist, this is fantastic!!!
CrashCourse helped me get through my undergrad. Revisiting much later, it's still highly relevant and a helpful refresher during my PhD studies! great work you guys!
I used Crashcourse today to teach my students biology! I feel like a success!
Aah ... 9th grade biology. I used to love that class. Good to hear all the plant tissue names and see familiar diagrams after many years.
Wish crash course history was as frequent as the Biology classes.

So happy that we're on plants now!
You have no clue how grateful I am for these videos they help me to understand bio from a different voice and you're so entertaining as well. Thank you Hank :")
I basically owe my entire biology degree to crash course
I find it interesting that this is my only educational channel I'm subscribed to but it is my favorite channel
I would just like to point out that in his second biology video he correctly points out that metric is used by scientists and "parts of the world where things make sense" throwing that out there at anyone still arguing which is better because honestly he is totally right.
Wow this covers a whole semester of materials.
Why is every fuking part of your face one color
Oumar L. Why so racist 😢
A whole semester? This was a single lecture in my first year bio class.
Teagan P This is America. Education : a mile wide and an inch deep. Still, it’s nice to start off with the ‘big picture’.
I knew plants were superior than us!
Plants Are coming OMG
its not gonna be the robots, or zombies, its gonna be the plants, hencie why theres the game plants vs. zombies.

I’m not even in school currently, but I always find myself watching these videos ❤️
I really wish Crash Course and Sci show had existed while I was in High school. I think I would have done alot better in my classes if it did.

You are the reason I got an A during my first semester of Bio and the reason I'm still holding onto an A in my second semester, so thank you.
the plant you are holding in the beginning is not yarrow, but the artwork on the title page is yarrow aka achillea millefolia. If you compare the two, you can see some differences. Even though the camera work on the plant is blurry, it can be seen clearly enough to tell.
Hank you are the best Too many other foreign commentators too hard to understand or others too slow. You make it all make sense!!
Studying for Bio midterms... SO MUCH MORE FUN THAN I EXPECTED.
I love watching these episodes. Just started college and need all the educational help available. Not sure how we went from plants to the metric system on the comments but if your an American supporting the metric system you apparently did not grow up working on cars. It may be hard to understand but mechanics are proud of their standard system.
102% in my biology because of these videos and TH-cam in general . thank you for the videos they are awesome
Using this for an AP biology test next week. Thank you so much for this!
Great information given in almost 12 minutes. Many thanks for ALL of your videos :')
I agree, the only place where the imperial system is used in New Zealand is with new born baby's weights, and this is slowly changing too
You teach really fabulous,
i love learning from hank and john :)
I think it makes more sense to say that plants make continued life on earth possible.
Congratulations; you guys are apparently the only reason my first year students are able to pass my class.
So grateful for these videos.
They teach this stuff to us in our seniour year. (Yup, I mean in highschool). I have been trying to find a decent vid on the subject but I couldn't find it in my language which is Turkish. This vid just saved my life for real. The final exam, here I come!
Thank you for the vid!
Hank trying to add history to crash course biology to compete with john is adorable :)
As an American supporting the metric system, I hope Crash Course does start using it, as well as the rest of the nation but I'll take what I can get.
As a Indian supporting a Norwegian supporting an American supporting an American supporting the metric system, I hope Crash Course does start using it, as well as the rest of the nation but I'll take what I can get. Start the chain!!!
I’ve been attending a science class and the topic was vascular plants. Thanks for giving me an idea!
And this is why I'm majoring in Botany.
Thank you so much I feel to have been Blessed beyond measure to have found someone who makes science so simple as you do..... May God Bless you more for your tutoring....
If it makes you feel any better, I have a test about this subject (mostly building plans in gymno-, and angiosperms) tomorrow
Crash Course makes studying easier for my AS/A Level Exams.
Aaaaaaaactually, that redwood is only the TALLEST organism in the world! The largest one is a honey fungus in Oregon, which measures around 2.4 miles! :D the more you know!
HOW DARE YOU DISRESPECT MY HANKY BOI
@Zelia Eastman by massive he meant the weight. He said they weigh more than 13 million pounds.
I love these videos and they are going to help me ace biology this year
Hank, I love what you're doing here. Keep up the good work.
Hey, I like the video, but could you use liters instead of/ in addition to gallons? It's really hard to picture for most of the world :)
YES! A little bit of herbalism on CrashCourse! NICE! Hooray! Go plants! Help people help plants help people!
thank you and these videos sooooooooo much for helping me pass my a CLEP bio exam! :) :) :) :) :)
Crash Course team you have taken my most hated part of Biology and actually made me understand it. Sadly 10 years after I left high school with that big ugly C on my final results paper, but better late than never. Thank you!
Always appreciate your videos!👍
Got my buddy to watch a couple episodes of Scishow... He went home and watched them all, lol. You guys are amazing!
These videos are the best videos ever
I hope this counts as studying for my Biology exam
Beastly introduction as always :O
My Bio teacher showed this video to my class the other day!! :D
I love you hank sir
Oh I believe this is an unanswered question on Ve's channel, how water is transported up by plants. Thanks Crashcourse for explaining to us and in great detail too.
The best channel for science students..... I like teaching of a Hank green....😊
Hey cool! It's Hank from SciShow! :D
YES MOM!...I AM STUDYING FOR MY BIO TEST!!!....
they exist because we need them
and if you sniff *sniff* it smells like butterscotch
As an American supporting an American supporting the metric system, I hope Crash Course does start using it, as well as the rest of the nation but I'll take what I can get.
Hank I love you. Why have I not used these videos before?!
I love this videos for study to a final exam! The videos help a lot
these videos got me through high school and now they're getting me through uni
Whoever did the graphics for the title page: wow
just LOVEEE this channel
I remember learning this stuff in Highschool. (It feels so long ago). I wish Hank had been my teacher. Even though it was my favorite subject my Bio teacher was as interesting as a rock.
