Why Don't These Plants Need Seeds? (Moss and Ferns): Crash Course Botany #8

[@crashcourse]

The answer to the extra credit question is… sphagnum moss! What plant would you like to thank for its helpfulness?

[@kbrcomplexly]

i'd like to thank aloe for alleviating the sunburns i get on my unfortunately pale skin 😅

[@kingpopaul]

Was also used as menstrual pads.

[@QuiteSanelyInsane]

Sword ferns! The orange sporangia on the underside of their phyllids can be used to treat minor cuts, abrasions, and even stinging nettle :)

[@amandas5398]

I’d like to thank stinging nettle - for the medicinal help it provides to humans AND the boost it’s presence gives to other plants in my garden!

[@Stephshouse23]

I’m in love with this series I wanted to be a plant scientist but life has taken me down a different path. No other show teaches with accuracy and enthusiasm than this. With Crash Course I have access to knowledge I would otherwise wouldn’t know where to begin without paying for classes. Thank you thank you thank you! I’ve been watching crash course since I was 14 in biology class freshman year in 2014 and I just want to say that I believe wholeheartedly in cc and hope one day I’ll be able to support the next generation of curious kids like me ♥️

"Mars will come to fear my botany powers." Today, I learned something about evolution. The living beings that branched earlier, haven't stopped evolving in their particular ways. If they are still alive, is because they are still successful. They aren't primitive or lower. They are tough and smart.

[@Beryllahawk]

Ferns and mosses are the BEST. I have always loved them because they look so soft and green, they really make me think "this is a lush place"! I'm starting on a journey this year to learn how to propagate ferns, too - I have a beautiful patch of them and I want to get them in many more places in my yard, I just have to learn how to help them do their thing! It promises to be a challenge but I'm excited!

[@99721]

You could say the Bryophytes are much _more_ evolved, since they are older and have had more time to diversify and perfect.

[@Go4Noctis]

Nice thought but no because EVERYTHING alive has been around the same amount of time and has been evolving the same amount of time.

[@erikholgersson9235]

But that is only the case when you start setting hard lines for when a species is a new species. I mean humans are a recent species, but our ancestors are responsible for evolving into humans. So you have to count that time evolving into humans as well. This view would mean that all species on earth have had equal time to evolve since we all came from the same common ancestor

[@marim0y]

Mosses are awesome. I loved this.

[@guanabanajuice13]

This is my version of Saturday Morning Cartoons. Thank you so much!

[@joshuaharrison9331]

The group of plant-nerds I go to uni with are Bryophyte obsessed - They were the first plants I learned to key out & study so I still have a keen respect for them & their pioneering niche.

[@thesocialnerd]

Yay! New episode! Loving the series so far Also, looking at my lil rabbit foot fern while I watch this episode and letting her hear about her ancestors lol

[@fayem4091]

This is my favourite series ever!

[@Shake1]

Highlights to brazil, i came here by a colleague recommendation and JUST LOVED the way you teach, it's nothing like a botany book you could borrow in library but it is all contextualized and rich of content and love. Although, i'd like to request some captions since there are many scientific words and some others i couldn't get

[@duskadown6751]

I love moss

[@Anuchan]

This video has spurred my desire to learn more about botany. Thanks!

[@canis2020]

I lichen these videos so much!

[@georgigeorgiev9931]

I love masses 💜 Used to have them as mount wall

[@Sylvia8-z6c]

I like listening to your video to learn English.

[@stax6092]

You Said think of a Plant and I immediately thought "Fern". Wasn't sure if I should've thought of Moss.

[@corruptedsociety_]

I’m not in school, but I love crash corse regardless

[@esteriistiel331]

I almost remembered the answer to the extra credit question. I was gonna say it's called old man's beard lichen, all because of the game "the long dark"

[@KerrikkiLurgan]

Mosses are my favourite plants

[@gucciflipflops6064]

It would've been awesome if I had this video to study for my exams during my first botany course 😭 The alternation of generations confused me to no end but it's never to late to understand old information! Thanks thought bubble!! 🫂

[@boehrb]

I'm lichen those fluttery butterfly hair clips!!

[@lr8786]

Her butterflies are cute.

[@novice7T7]

if plants took over all the soil how many plans would there be or would huge plants spur in groups.

[@sydneyschmidt4267]

Alexis you’re the best!!! Your foraged veggie tik toks blew my mind when I first saw them:) so cool you’re doing crash course botany! Can’t imagine a better person!

[@samwill7259]

Like any good science teacher, she's tossing out the puns thick and fast. Bless

[@Ganymedescup]

Dress my wounds with that peat moss, please.

[@MeatPops]

3:35 A lot of fun-gis were hurt by this statement.

[@therongjr]

0:48 - I don't think those are liverworts? It looks like the right kind of environment for them, but they look like some are on stems and have radial vasculature.

[@dapprligtnin98]

Oh sweet Narcos Mexico Season 1 memories come back to me, COME BACK TO ME!

[@AdnicajChiquis]

I hit 👍 at "mossome"

[@mercuriallimit]

my god, braided hair WITHIN braided hair!! it looks so nice.

[@imgooley]

The thumbnail madee hear yahaha! In my head

[@shawnholbrook7278]

Lichens!

[@Sunflower-sg1it]

she is so pretty

[@JulianPatrickMiller]

Alexis!!!!!

[@Shehz-95]

Why is Crash Course getting quite low views these days?

[@GamerKimberly191]

Ummm cool

[@katsomeday1]

The first multicellular life on land isn't plant or animal. The oldest known land life fossils, (about 135 million years older than plans,) is fungus. Why is it educational shows like this always seem to forget the third kingdom of multicellular life fungi.

[@drsingingeagle]

So do liverworts have livers? How about warts? 😜

[@camiloharritt3007]

Amazing video

[@pedrostormrage]

13:08 The bryophyte that can be used to dress wounds is the sphagnum (or peat) moss (you can see it at 4:53). It is known to absorb moisture a lot quicker than cotton (90% percent of the cells in a sphagnum plant are dead, so they can be filled with water), in addition to being an effective antiseptic (the plant's cell walls have negatively charged sugar molecules, which attract positively charged nutrient ions (like potassium, sodium and calcium), which when released make the environment around it acidic, inhibiting the growth of bacteria.).

[@67comet]

I "LOVE" your energy! You're an awesome addition to the Crashcourse crew!.. We appreciate you!

[@NickGamer1Bmv]

Thanks for the new knowledge

[@roxcaz]

Great Course. Thank you

[@CristinaMCGil]

unrelated to plants, I'm mesmerized by the butterfly clips in your hair!! they move!!!

[@rckli]

I loved all of this, her attitude, and this weed I’m smoking 🎉

[@chocomalk]

Gotta be the cutest thumbnail ever lol

[@Syco108]

Gurl! That hair! You're killing it! Thank you for the plant knowledge❤

[@sarahgriffith1424]

Alexis is awesome!!!!

[@therongjr]

Your energy is amazing, and I'm so happy that you have the same love of liverworts and club-mosses that I do! 💚 They don't get enough attention . . . and the alternation of generations is somehow so alien to us, although it's all around us! 😮

[@Davlavi]

Love furns.

[@muahlakaparak]

Beautiful👍

[@electroxyz5674]

i have waiting for this video thanx🥳👌

[@ponyote]

Here from Be Smart. Yay plants!

[@sankimalu]

The host with the MossT…

[@corgi42069]

Your enthusiasm is infectious!!

[@caitlinhanson2773]

Love Crash Course. Is there any possibility of the Literature part of Crash Course to do an analysis and summary of George Lammings "In the Castle of my Skin", I have been struggling to grasp it a bit.

[@christopherwarner6896]

Def favorite episode so far!

[@Flow_3801]

This is so educative to listen to, i wish this video came earlier in my high school, nice work

[@hrhevansjohn8528]

👍

[@itan96]

Those butterflies in your hair are so awesome!!!!! Can't get enough of them!

[@elainewu7266]

Sphagnum mosses

[@shawnholbrook7278]

Is the answer spaghum moss?

[@KifoNemkana]

[@nicolenew1708]
