One of the better explanations I've heard for this one, well done! I suppose some folks might feel they've heard this story before, but still it's WELL stated, and that counts for a lot! That cape is very stylish, by the way, hehe!
I swear I just saw you on my Instagram page talking about "leave the leaves". I'm into it! Going for a degree in Natural Resources- Ecological Restoration. Thanks for explaining things in a way I can understand.
Don’t think you are the only one who writes elaborate botany fan fictions, I do too. I’ve made an entire world known as snorin, when plants are purple instead of green. There are a lot more similarities between snorin and Mars than snorin in earth, but it’s still very wet there.
11:19 Problem with the "magic" of biofuels is that mass-producing them is heavily dependent on fossil fuels. So we are still, though indirectly, burning fossil fuels and increasing CO2 levels…
Another - possibly bigger - problem is that they tend to get grown on the world´s limited farmland. Which we kind of already need to feed billions of people so it´s going to be hard to also use it to grow a significant part of our fuel. (Unless it comes from waste products but the kind of stuff you use to produce fuel is also the kind of stuff you don´t throw away in bulk.)
There's a lot of research being done in using solid waste (which has downstream versions of plant fuel) as a biofuel source material. Also, industrial byproducts of plant material like sugarcane fiber and wood pulp are examples of ways to take waste product on existing farmed land (or working forest land) and turning it into a biofuel input. As for the combustible, that is a more complicated problem but not an unsolvable one I think!
At 8:27, you label the processes "anaerobic respiration", while the diagram calls them fermentation. The diagram is right! Anaerobic respiration is very different & requires the electron transport chain. Fermentation starts with sugars like glucose and is definitely what plants do!
Plants must produce less CO2 than oxygen or they wouldn't be considered a carbon sink. Does anyone know what's a typical ratio of CO2:oxygen outputted?
The answer to the extra credit question is… bacteria! What’s another fact that makes you realize the smallness of humans?
That fungi are still higher on the earth biomass scale that animals!
Protozoa can also use photosynthesis
The fact that we are made up of atoms from several suns which could have been so big they would have reached Jupiter if swapped for our sun
Also giant red wood trees.
THOUGHT CAFE MADE THE LIL MITOCHONDRIA SO CUTE 😭
Eyyyy 🤩 Thank you Miss Alexis for making every lecture entertaining and memorable, I really enjoyed this series 💯😊
Omg! Alexis!! Thank you so much for all the educating you do here on Crash Course as well as on your other platforms. You're a treasure!
Thought cafe makes EVERYTHING adorable
I’m currently at university majoring in plant science. I wish all my lectures were like this! So engaging and love the graphics.
such an amazing and informative video!! i love plants and learning everything about them :))
The cell animations are adorable 🥺
This finally got me to understand why photosynthesis and cellular respiration are different. Ready for my test now!
Good luck! You got this!
This is my favorite episode. Thank you so much for lowering her voice a lil. It made it easier for me to watch/listen & I really appreciate that 😊
I had three uni courses on plants but i still see this with graphs and i am WOW ALL OVER AGAIN

As a Trigun fan, I can assure you that you are DEFINITELY NOT the only person plotting elaborate plant fanfiction.
Thank you, I always use your videos to prepare lessons for the botanical garden ❤
I love listen to their biology videos when cleaning as a brush up
You're the brightest person out there ☀️🪴🌿🌵🌱🌷
Thank you so so much for this series!! You are an amazing host girl!

Biofuels and related are fascinating. Thank you!
You are fantastic!! Thank you for your enthusiasm!!!
Love this. Love the magician references.
Loving this series!!
Either algae or fungi make up the next largest group. Great video, informative as always. Keep up the great work, you are amazing Alexis!!!!
Actually our host answers this question in her comment above -- it's bacteria! But I thought fungi at first too!
Wish I had this in grade 10! Great video :)

Loving this show
❤ Wow this is an amazing video love to the editing cause you can’t do magic
OMG Dr. Gadhamshetty was one of my advisors!!!!! Hi Dr G!
At 8:27, you label the processes "anaerobic respiration", while the diagram calls them fermentation. The diagram is right! Anaerobic respiration is very different & requires the electron transport chain. Fermentation starts with sugars like glucose and is definitely what plants do!
This host was amazing, made the video 💯
6:22 I beleive the term for this is "autotroph" 😁
Loved it. 👏
Thank you!
excellent video
Great video. Thank you 😊
I got sent here by my Science teacher, help 😢
Crash course should do an episode about invasive honey bees in north america and their devastating effects on the native pollinators!! ❤
Fungi are probably the next in the big percentage of biomass
Love this episode! And is it just me or does that oak tree at the end look a lot like a maple tree
Can't wait for "50 shades of Green" to drop.
THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL
ALEXIS!!! 😍
Bacteria is second for sure. There are just SO many bacteria, but they’re on average much smaller than plants.
My guess for the second largest contributor to earth’s biomass: funghi/myocell.
I believe that bacteria are next after plants in terms of percentage of biomass on Earth.
Second largest Biomass - Insects
oh yeah, I was going for ants, but that's more accurate.
I just love the narrator @theblackforager! This is amazing!!!
got a test on this in 10 minutes wish me luck🗣️🗣️🗣️
Flashy way of learning!
Will you talk about mushrooms?
Wowza early bird
Do plants have unequal rates of photosynthesis and cellular respiration?
Second largest group by mass is bacteria, third is fungi.
I still want to see the plant rebellion. The day when all plants will rebel against human domination.
the source is a Google doc created... by you?
Did i iust find black forager on PBS?!?!?
Biomass q bacteria made up about 15-20% of the total biomass on Earth
oh, to be a plant
👍
Plants must produce less CO2 than oxygen or they wouldn't be considered a carbon sink. Does anyone know what's a typical ratio of CO2:oxygen outputted?
Bugs. Ants specifically
are all crash course video is full course knowledge
I'd say, ants! They're everywhere!
I was just thinking leaves are like the solar panels of plants.
Prolly.... uh worms(like all forms, since even they're barely closely related to each other
But apparently it's ants and termites
Why does it matter how long the carbon has been locked in the earth? In terms of saying that biofuels are more climate friendly than fossil
Nematodes?
Bacteria followed by Archea
black forager the same as crash course
It's not really magical but more like miraculous.
First
I don’t know what brought me here
Somehow using edible plants like tomatoes, soy and corn to produce energy instead of food sounds like the priorities aren't right...
Insects
Insects?
Ill break it down for you bit…. by bit
I’m pretty sure the answer to today’s Q is ants.
