Plants-they’re just like us! Well, not exactly, but they do have skin and hair like us…even if they also have creepy little alien mouths. In this episode of Crash Course Botany, we’re getting up close and personal with plants’ anatomy by diving right into plant tissue under a microscope. Let’s learn what plants are really made of.

The answer to the extra credit question is…light bulbs in asparagus cans! Tell us about a time you’ve had to DIY something sciencey.

i made a telescop inn my childhood using glasses lens, paper for tube and some other lens from some broken camera or so for the ocular - we did not have much choice back in ussr so it was not just for fun but also for nessesity

How was anyone supposed to know that if you didn't tell us? I didn't realize this was the answer to the question from this week's video and tried to figure it out myself. I've got the internet and couldn't figure out the answer.

Eventhough I've known that leaves have a vascular system, but it's still so weird to me how closely it parallels the animal vascular system with blood. Makes cutting a leaf seam abit more violent.

Nice slides! It's been literal decades since I learned any of the basics, but never once did we get to see images like THAT. Only drawings in the science textbooks - which, I'm not knocking those, science illustrators have one of THE coolest jobs and sometimes a very challenging one. But those pretty and simplified pictures just don't convey the organization and complexity the same way. That said, I do still recall even 30-plus years later, the demonstration of "how xylem works" using food coloring and a stalk of celery. The slides are cooler though!

I’m going to start a backwards, rainbow connection, purple-first; red final. “ do you know how I got Philadelphia so well memorized, it’s all the pool ponies I got from my purple back. Now I even like the taste of dandelions sometimes; assuming it’s not the only thing I eat. FM comes in different colors I believe; in the potion machine, I have lost myself. The scrapbook holds membranes. I am sometimes too afraid to confront!” Nigel Goldman, who is head-canon by me as a deep one. he knows his way around the tide pool!
