The way you explain things is so clear, and you add just a little bit of friendly humor which keeps things upbeat. you are a great teacher man, you inspire me.
It took my professor two semesters to teach our class this stuff and he didn't even get it correct. This 14 minute video is worth two full semesters of my horticulture college! Thanks for the video man!
our teacher really sickens me, he makes this subject so boring, cuz he hates his job probably and doesnt like teaching. But when I watch these videos I love it! :)
gracias mr anderson for explaining this process clearly. This and all your videos have helped me a lot to understand how impressive and necessary plants are for our lives...muchas muchas gracias!!!!
I've been studying chemistry and botany for around a month now, and this is the BEST video I've come across on plant structure and function. Many Thanks. Great stuff.
Hi, I find this video very useful for teaching, so thank you for creating it. One of my students just pointed out that at 3 minutes 42 seconds you have your pictures of monocotyledon and dicotyledon stem cross sections the wrong way round. The monocotyledon stem is the one with the scattered vascular bundles and the dicotyledon stem is the one with the bundles arranged in a ring.
These are our biology teacher who hate him because he is doing a better job then they do, takes him 14 minutes to explain something that takes a week at school
I really enjoy your videos. I'm not in school right now, but I enjoy plants immensely and when I do get to school I want to major in plant biology or somewhere in the field of plants. Again, awesome video.
This was amazing! Thank you for a clear summary and a clear diagram for the Phloem and Xylem transportation. You explained my proffs very confusing 5 power points clear as day.
The easiest way to explain the way in which water is sucked up from the roots and to the leaves is to think of the process in reverse. At the end of the waters journey the excess water found in the air spaces inside the leaf is released through the leaves stomata into the atmosphere, this water is then replaced by water evaporated from the surface of the mesophyll cells, this process causes a transpirational pull and lowers the cells water potential, this in turn allows for the mesophyll cells to take water from neighbouring cells through the waters potential gradient. This process of water loss connects back to the tracheids (water conducting cells found within Xylem) and causes water to be taken from the Xylem, this water then travels along the tracheids into the air within the leaf following the water potential gradient. Xylem travels up the stem of the tree by the action of a water potential gradient, water moves from an area of high potential, to an area of low potential, gradually moving water up from the roots. Waters natural cohesive and adhesive properties and the small diameter of Xylem aid in its movement up the stem.
for the unloading of sucrose, it would have been nice if you would have explain the mechanism as well such as the use of hydrogen ion as co transporter etc...
I wish we had this level of Technology when I did Science at school - No wonder our kids are getting higher grades with the presentation capability available in 21st century!
I have studied this stuff for ages. The water has a positive and negative charge within the plant cell walls.everytime the night time and day time go up and down the gravity pulls the plants waters and sugars over time within the xylem.
Anderson talked about casperian strips being A waxy cuticle at 8:46. But they are suberinized thikenings, how can they be waxy and be treated like the cuticle present over the epidermis in stems?
Bozeman i think you must have mentioned this point in like 3 words, or not but hope it helps you all 207,052 people or more. Xylem vessels are single tubular vessels, so they transport water from the roots, to the stem and then the leaves for transpiration 'Phloem are multi tubular vessels, so they transport glucose around the plant and when stored, it converts to starch.
Great presentation, very clearly explained! Just one mention: :stomata" is the plural form. When you refer and show a single one, you should call it "stoma" instead.
It depends on the time of the year. We know carrots to be sweet because we harvest them in fall (after photosynthate has been partitioned to the root). If a carrot were left to overwinter, the starch would be hydrolyzed and then transported into the new leaves the following spring.
Very good for 7 years ago or perhaps all the better for it. I'm looking at at the idea of optimising nutirient application by looking at a leaf under a microscope. Is this possible do you think? Needless to say you can assess this from the point of view of the bottom leaves...... those are the first to be sacrificed...... but I want to take it stage further than that. I want to be able to look at microcope slide and say I think I can wack on say another 25% or 10% feed to optimise plant growth with out causing root toxicity. Thoughts anyone?
Thx for the video, it was really helpful. One thing that I don't get though: do roots ONLY use defusion? How do they absorb nutrients? The word "transport proteins" is moving through my head. And what about ions? How do plants absorb them?
Sorry Sir, I wanted to ask if you could please clarify the Dicot example in your video. You used a cartoon of a flower with 6 petals instead of 5/4 for the Dicot. Your videos are great! Thank you.
Hi Paul, Just curious, shouldn't the root (carrot) be the sink, as it is where sugar is stored? The source should be the leaves, as this is where photosynthesis takes place. Your videos are fantastic...keep up the great work! Lee Ferguson, Allen HS
Woah those slides actually look like what we prepared and saw in the lab!! But this was more helpful cuz he actually told us what that was and labelled it. Our teacher just made us see 'em but didn't explain much. _sigh_ why do biology teachers suck in real life
If any one deserves TH-cam money, it's this guy.
Good plants for us
Indoor plants
seriously! he does such a good job. some videos I have a harder time, but in those times khan academy has been very helpful
ziji helium yup
ziji helium Ij

Well said.
So true. His videos are so helpful
Aishah wrong explanation.
Happy teacher appreciation week! You have helped me a lot! From getting 50 to 90 percent on exams!
best teacher i have seen . my bio teacher teaches the same thing in 10 days and we dont understand. 14 mins here and i have the full concept.
ikr!? this man did a very good job presenting this. 10/10.
That says it all! I second that emotion.
The best teacher I have ever seen in my 15 years of education life.period.
It took my professor two semesters to teach our class this stuff and he didn't even get it correct. This 14 minute video is worth two full semesters of my horticulture college! Thanks for the video man!
Frank Phillips ... Hai frank I need guidance in filed study of horticulture . expecting Ur reply.
Frank Phillips hahahahahahah
11:39 ''well these cells are empty, so how do you be alive and be empty'' Same.
you've saved my life so many times
facts me too
Prof. Anderson videos are so great, he's such a hunk !
our teacher really sickens me, he makes this subject so boring, cuz he hates his job probably and doesnt like teaching. But when I watch these videos I love it! :)
gracias mr anderson for explaining this process clearly. This and all your videos have helped me a lot to understand how impressive and necessary plants are for our lives...muchas muchas gracias!!!!
the best teacher on youtube........
saved my butt over and over!
You explain things so plainly and efficient. MUCH better than my professor. Thank you :)
I've been relearning the concepts of biology after 20 years since graduating as a hobby. This guy has the best diagrams and explanations bar none.
My garden is gonna rock after watching all these videos...
This man deserves Nobel prize!! 🏆
these video are so helpful my biology test is this Wednesday. Hope for the best:)
I've been studying chemistry and botany for around a month now, and this is the BEST video I've come across on plant structure and function. Many Thanks. Great stuff.
last minute cram sesh. you have saved my life in this class, not joking ive learned more from your videos than a year from my teacher

A well deserved teacher. This video is awesome
Really informative and also entertaining. Your teaching style keeps me attentive. Thank you! This has helped me in my college Plant Physiology course.
How can anyone dislike this???
These are our biology teacher who hate him because he is doing a better job then they do, takes him 14 minutes to explain something that takes a week at school
haters gonna hate
Angry Biology Teacher: "This guy is teaching better than me. So I don't like it"
Thanks a million for this excellent presentation. This has been a huge help towards my RHS studies in the UK
Thank you Bozeman! Your videos are always so inciteful and very helpful.
Last minute studying for the bio sat II subject tests tomorrow
I can relate
How did it go?
Lol, same!
did u pass
Same
I really enjoy your videos. I'm not in school right now, but I enjoy plants immensely and when I do get to school I want to major in plant biology or somewhere in the field of plants. Again, awesome video.
I freakin love you Mr.Andersen
botany is usually a pain mostly in high school but u make it fun!
You are a good teacher of science
God bless him. He truly deserves the world🌹❤️👏👏🙏
I'm studying for the Dental Admissions Test and you're videos have been very helpful!
Jacob Prows wait, what?
Watched your videos in AP bio and even in college, these videos are still useful!
This was amazing! Thank you for a clear summary and a clear diagram for the Phloem and Xylem transportation. You explained my proffs very confusing 5 power points clear as day.
Got my Bio Exam tomorrow for 1st year BA in Horticulture. Very helpful!! Thanks :)
You’re a blessing to my biology grade.

Now I understand the whole process of how water travels up to the leaves .. thanks
Your videos are awesome! Thanks so much for helping us to understand science.
Thank you for these videos! I use these as a review for my botany class because my professor doesn't go into much detail
Amazing video! Summed up all the concepts in this particular area perfectly! Keep doing what you are doing because it is extremely helpful.
As you can see, we've had our eye on you for some time now, Mr. Andersen.
the best one! my teachers need to learn a lot from you too. thanks anderson for this amazing video
i feel so so so much better about my biology final now!! mr. anderson is keeping me motivated. dont have to change my major lol
Tank you! I've always wondered how nutrients are being moved around in plants mechanically. No I know that and a bunch more!
EXCELLENT TUTORIALS PAUL, THANK YOU!!!
It just makes since when he explains it🌼
9:07 “You shall not pass” are the scariest four words you can say to someone before an exam
Hey Mr.Anderson... Thx for d video.... U made me understand.... Thnk u again
for the unloading of sucrose, it would have been nice if you would have explain the mechanism as well such as the use of hydrogen ion as co transporter etc...

I found the leaf structure very fascinating.
Thank you so much for publishing these videos! You are helping me so much refresh my Bio knowledge :)
great video man. you make things easy to understand

You are the best. You are the saver of my life.
YOU ARE AMAZING ...really thank you for doing this.. !!!!!
This 14 min video help me a lot 😄
Thanks so much for your awesome videos! So helpful.
You are absolutely phenomenal.
This video was very helpful. Thank you.
Congrats on 1 mil
I like your lectures so much
Thank you! Your videos are so professional and ah-mazing! You should have a lot more views!!! :D
Thank you for excellent work! It really helps!

You Sir have all my respect.
this is so wonderful, really helped with my revision thank you so much
Amazing! So helpful and clear, thank you so much for making these videos :)
Nice video. pretty much all your videos are nice:) helps me alot! thanks :)
When you need a hero, this man is here
Such an awesome explanation. Thanks!
Thank you for the video, it was really helpful and ur explanations were easy to understand. :)

Thoughts anyone?
OMG you are the best!! I love your videos!! Thank you soo muchh!!
Love it.. its getting simple ..to understands
Learnt alot from you. Great vid!
best video! can you please talk about sonic bloom co-relation of birds and plants?
Thx for the video, it was really helpful. One thing that I don't get though: do roots ONLY use defusion? How do they absorb nutrients? The word "transport proteins" is moving through my head. And what about ions? How do plants absorb them?

THANK YOU SOOOOOOOOOOOOOOOOOOO MUCH!!!
Great video!
better than my university professor
Superb.
that tree has some serious girth !
Do you believe that one can stimulate roots with electricity to boost productivity of growth?
Very helpful to online students like me 😀
If wasn’t for you I will prob fail biology THANK YOU SO MUCH😭😫
Hi Paul,

Your videos are fantastic...keep up the great work!
Lee Ferguson, Allen HS
love Gandolff for casperian strip
O.O What's the name of that giant tree at 2:00??
Thanks! I was so lost reading the book!
it's easier to study,explanations ar very clear
Great video
Video teaching is very effective! Thank You for uploading. Are you a teacher?
Woah those slides actually look like what we prepared and saw in the lab!!
But this was more helpful cuz he actually told us what that was and labelled it.
Our teacher just made us see 'em but didn't explain much.
_sigh_ why do biology teachers suck in real life
Where did the CO2 appear to the atmosphere in the first place so that plants could use it for glucose production?
Thank you so much!
