Pardon this geek-out. I've studied this subject and I love it. To add to the category of mutualists: endophytes. Fungal endophytes live in plant tissue walls where they can be beneficial or antagonistic. Sometimes one species of endophyte will be beneficial in one plant species but antagonistic in a different plant species. They produce secondary metabolites that can serve all kinds of strange purposes in a plant. They are also believed to be nearly universally present in plant species.
The ant head invading fungi.... so good, this makes the chest erupting things from the Alien movies seem quite tame, by comparison. Great Video, what a fantastic channel this is.
My biology teacher liked to say "If someone asks you a question about biology the answer is probably one of those four words: "enzymes", "proteins", "surface maximization" or "key-lock principle"."
the whole "key-lock" principle of enzymes turned out to be wrong, didn't it? The enzyme wraps around the substrate, so the analogy doesn't really work anymore.
The ants can actually tell when a single ant has the fungi in its head and one of the worker ants will carry it far away from the colony so more ants don't get infected. It's amazing really.
When I knew we were getting into the study of fungus, I was a little skeptical about the capability of making this interesting, but Hank is just made of entertainement
At 6:20, you say that lignin is degraded into glucose... That's not true ! Lignin is a polyphenolic structure, not composed of glucose at all. I guess you confuse it with cellulose :)
This review was very helpful. I am reviewing for my MT exam in Microbiology and did not work in the mycology section of the lab, so I need all the help I can get! My kids may even watch this, hopefully!
This guy'd be cool for a Geo Romero film - NIGHT OF THE LIVING FUNGI ! (Theater trailer narration): "They Feast On the Deceased - nothing is safe from their ghastly appetites - not even bats. It happened to them - it could happen ,.. to you." Sequel - DAWN OF THE ZOMBIE ANTS?
Its an interesting thought, fungus are closer to the animal kingdom than the plant kingdom, they inhale oxygen and exhale co2 just like us, and they give us this "spiritual" insights.. If you eat enough of it i guess you are starting to believe it's an extraterrestrial lifeform itself hahah, jokes
I am 70,I wander forests and nice places living in my tent for 6 months a year. This year I decided I would find and take photos of lichen and fungi. Thank you for the info on what they are, what they do. Great stuff!
The 1.5 million spp estimate may now too conservative. That estimate (David Hawksworth 1991) was calculated from data before the start of the Next Generation Sequencing (NGS) era that allows for discoveries of greater fungal diversity per sample as well as the surge in fungal DNA sequences databases such as BLAST and UNITE. Accounting for fungi living in the tropics, aquatic, marine, and other habitats, the current range may be anywhere from 1.5 million to 10 million fungal species, with 5.1 million species being the most cited median value. Fun fact: It's estimated that at most only 10% of all fungi can be grown artificially. The remaining 90% require sequencing for discovery and identification.
I remember watching your videos when I was going to a municipal competition. I got 3rd place on that and I continued to a regional competition which I got 1st place on. Now I'm going to a state level competition this Sunday. I honestly don't know what else to say expect thank you❤️❤️❤️

Josh Jackson you’re right here’s a passage taken from ThoughtCo. Instead of just ending with the product of glycolysis like fermentation does, anaerobic respiration will create pyruvate and then continue on the same path as aerobic respiration.
Thanks again Crash Course. Love your work. I have seen so many of your videos! Very helpful for getting started on a topic and for getting into the geek mood. x
Any kind of grain could work. Back in the day they used rye flower because it was cheap. They put the past in a warmish place and the next day, it grew 3 or 4 times its size. They mixed that mixture into their breads and found out that it made it airy. Try this, put 1 cup of flower into a bowl with 1 1/2 cup of water. Put that on top of the fridge or a counter and after 12 hours, put another cup of water. Wait 12 hours and see what yeast is in your house. You can use that yeast to make sourdough
Hmm you say you make ideal conditions for yeast by giving them "lots of suger and oxygen" (at the end of the video) I don't think this is too clear. If a brewer does this in fermentation you won't get any alcohol because it needs to be anaerobic respiration to produce alcohol. Did you mean to make the yeast plentiful before putting it I with the sugar?
The initial increase in oxygen is used to boost the ability of the yeast to reproduce, thus increasing their population. Once the oxygen is consumed, the mode of aspiration changes and they go off and CO2 and Ethanol and some other trace esters which give various varieties of beer their characteristic flavor profiles. Brewing is fun(gi) lol
I really do appreciate all the information that all of you put out on TH-cam I've been watching your channel now for awhile the multiple channels all of you have and all I want to say is keep up the good work you're very informal they helping my son with his work and I recommend this channel many of y'all's other channels to people searching to find more information
Yes and no. The illness could theoretically jump to humans but it wouldn't be able to take over its host's mind so quickly. If you got bitten on the arm, it would take a month at the very least to reach the brain.
An interesting thing to think about : What if there where symbiotic fungi -or other types of liveforms- which would have a "relationship" to humans ? Edit (02.03.2015) : This comment is 9 months old - So, yea...
The Pip Parasitism is a type of symbiosis. You're confusing it with mutualism. When it helps you, and you help it back, you are mutual AND symbiotic. Symbiosis literally means living together. A parasite feeds on you without you knowing about it. That is still symbiosis.
take a good look into the human microbiome, there are strong arguments to be made that people are less themselves than they are a collection of other organisms (especially when you look strictly at cell numbers; we have more symbiotic bacteria and fungi in and on us than we do our own cells). symbiosis is something that is WAAAAAY more prolific and complicated than most people can imagine and it quickly becomes a philosophical debate about where to draw the line between symbiosis and ecology. NOTE: i am using the broad and scientific definition of symbiosis here (although most of the things in and on our bodies are in fact mutualistic or at least mostly mutualistic) with 'sym-' meaning 'together'. the commenter above is using the more colloquial definition which actually is closer to mutualism (which is a type of symbiosis)
I became so happy when I saw this video in my feed box! I have always wanted to get a degree in Mycology, but it's a very small field so I'm going to have to settle with microbiology or botany degree :/
When hunting mushrooms carry them in a net or mesh bag. It allows the spores to dust off on the ground as you backtrack out of the hunting grounds allowing them to breed in more areas.
wtf you just gave an explanation at the beginning of the video why you say fungi with a hard G... YET FOR THE ENTIRE REST OF THIS SERIES YOU'VE BEEN SAYING IT WITH A SOFT G

Unlike with my real teachers, I can just rewind Hank to the point where my attention started wandering.
The more I learn about fungi the more impressed I'm with this group of organisms. Thanks for the helpful video. Great research as always.
Stop reading the comments and keep studying! :D You got this!
Fungus is amazing. I’m growing some in my drawer.
Would you consider doing a crash course mycology series? Fungi really deserve their own series not just one video don't you think?
I don't like mushrooms, coz I'm not a ... fun-guy
I'll leave now.

Wow, that is absolutely true. This bothers me so much xD my mind has been blown!
It almost sounds completely natural!!!

This is one of my favorite biology crash course episodes. Fungi. Excellent.

I'm a visual learner, and sometimes I think it would be nice to have diagrams in your videos.
Wow, what a straightforward and uncomplicated video - all facts, no tangents. Why can't we return to these simple ways?

0:03 my heart felt relieved when he said Fungi (Fung-eye) coz literally everyone around TH-cam's been saying FUN-GIE and it makes me panic sometimes💀🔪
Can you do a whole episode on zombie ants? It feels like more people should be aware about that kind of fungus
I definitely thought I was going to fail my exam in a few hours -- then I found this series. THANK YOU.
Did anyone notice that the book he's reading is blank?
This is one year ago but I think that was the page that connects to the cover or the page before the inside title so it was blank
No it was literally some random book that they picked and the book was literally the same one! They just changed the coverings!!!
@@leo-hao There are some books with that sort of covering, i dont think they did a change
This video massively plays down the importance and complexity of fungi.
Hank is such a fun guy :D
You mean a fun-gi
Bio test tomorrow - this is a LIFE SAVER!!! Tank you so much!! :) Good luck to everyone :P

You would love The Last of Us. Also username checks out.
Someone in my freshman writing class is going to write a paper on fungal reproductive cycles because he saw this video. Bless his soul.
Don't lie, you've said funji literally every other time in this series...
Ocean Bagel Maybe this was secretly his "cry for help" video.
This video is awesome! I learned more from this than any of my science classes!
I'm waiting for the
"The Zombie Ant Fungus" movie.
Someone make it please yeah!?🙋🏽
It exists, but its a video game called Last of Us. These fungus zombies with erupted heads are much more scary than regular zombs.
Yeah how about we don't make that

Only some fungi synthesize psychoactive drugs though, just like some other lifeforms do too. Idk why it's worshipped as some kind of God.

I can't quite explain why, but fungi are some of my favorite organisms. They're just so interesting and bizarre.

An interesting thing to think about : What if there where symbiotic fungi -or other types of liveforms- which would have a "relationship" to humans ?
Edit (02.03.2015) : This comment is 9 months old - So, yea...
there is! candida albicans, considered normal flora, but attacks you as soon as your immune system is weak or after taking antibiotics.
If something "attacks" you it's not symbiotic, it's parasitic. Only they are benefiting.
