If any one deserves KZfaq money, it's this guy.

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.

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.

11:39 ''well these cells are empty, so how do you be alive and be empty'' Same.

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!

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!!!!

Prof. Anderson videos are so great, he's such a hunk !

you've saved my life so many times

Thank you Bozeman! Your videos are always so inciteful and very helpful.

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.

Thanks a million for this excellent presentation. This has been a huge help towards my RHS studies in the UK

Amazing video! Summed up all the concepts in this particular area perfectly! Keep doing what you are doing because it is extremely helpful.

Really informative and also entertaining. Your teaching style keeps me attentive. Thank you! This has helped me in my college Plant Physiology course.

You explain things so plainly and efficient. MUCH better than my professor. Thank you :)

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.

A well deserved teacher. This video is awesome

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.

EXCELLENT TUTORIALS PAUL, THANK YOU!!!

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.

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

the best teacher on youtube........ saved my butt over and over!

Your videos are awesome! Thanks so much for helping us to understand science.

It just makes since when he explains it🌼

these video are so helpful my biology test is this Wednesday. Hope for the best:)

My garden is gonna rock after watching all these videos...

Thanks so much for your awesome videos! So helpful.

Thank you so much for publishing these videos! You are helping me so much refresh my Bio knowledge :)

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 :)

Such an awesome explanation. Thanks!

Hey Mr.Anderson... Thx for d video.... U made me understand.... Thnk u again

You are absolutely phenomenal.

Thank you for excellent work! It really helps!

God bless him. He truly deserves the world🌹❤️👏👏🙏

You Sir have all my respect.

Tank you! I've always wondered how nutrients are being moved around in plants mechanically. No I know that and a bunch more!

Watched your videos in AP bio and even in college, these videos are still useful!

the best one! my teachers need to learn a lot from you too. thanks anderson for this amazing video

YOU ARE AMAZING ...really thank you for doing this.. !!!!!

You’re a blessing to my biology grade.

This video was very helpful. Thank you.

You are a good teacher of science

Last minute studying for the bio sat II subject tests tomorrow

great video man. you make things easy to understand

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

THANK YOU SOOOOOOOOOOOOOOOOOOO MUCH!!!

Thank you so much!

Thank you for the video, it was really helpful and ur explanations were easy to understand. :)

OMG you are the best!! I love your videos!! Thank you soo muchh!!

Very much appreciated!

How can anyone dislike this???

I found the leaf structure very fascinating.

thank you for doing this

You are the best. You are the saver of my life.

This man deserves Nobel prize!! 🏆

As you can see, we've had our eye on you for some time now, Mr. Andersen.

very great. thanks

Love it.. its getting simple ..to understands

Learnt alot from you. Great vid!

awesome, ty very much.

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

botany is usually a pain mostly in high school but u make it fun!

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.

Thank you for these videos! I use these as a review for my botany class because my professor doesn't go into much detail

Nice video. pretty much all your videos are nice:) helps me alot! thanks :)

Brilliant !!!

I'm studying for the Dental Admissions Test and you're videos have been very helpful!

Got my Bio Exam tomorrow for 1st year BA in Horticulture. Very helpful!! Thanks :)

Now I understand the whole process of how water travels up to the leaves .. thanks

I like your lectures so much

AMAZING THANK YOU

Great video!

Thank you

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.

This 14 min video help me a lot 😄

Thanks!

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.

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...

man i love your vids, keep it up!:)

This was helpful!

Thank you! Your videos are so professional and ah-mazing! You should have a lot more views!!! :D

Superb.

AMAZING!

Congrats on 1 mil

9:07 “You shall not pass” are the scariest four words you can say to someone before an exam

Great video

weve been Expecting you!

thanks mate, your so helpful :D

You are the besssssssssst ever!!!!!!!

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.

this helps alot even for Cambridge A Lvls thanks alot

love Gandolff for casperian strip

best video! can you please talk about sonic bloom co-relation of birds and plants?

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.

I enjoyed it

Thx
