Vascular Plants = Winning! - Crash Course Biology #37

9506 ratings | 980182 views
Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and the their secret is also their defining trait: conductive tissues that can take food and water from one part of a plant to another part. Though it sounds simple, the ability to move nutrients and water from one part of an organism to another was a evolutionary breakthrough for vascular plants, allowing them to grow exponentially larger, store food for lean times, and develop features that allowed them to spread farther and faster. Plants dominated the earth long before animals even showed up, and even today hold the world records for the largest, most massive, and oldest organisms on the planet.

Wow, pressure differences cause the water in the plant to defy gravity and move up? I wish pressure could do the same to my grades.

Sclerenchyma cells in wood (fibers and tracheary elements) proper do not get pushed out when new wood layers form. They remain inside the stem.

Two things: One, I don't like when he says "by Zeus's beard" because nothing in Greek mythology actually happened. Two, EVOLUTION NEVER HAPPENED!!! God created everything how it is now.

They teach this stuff to us in our seniour year. (Yup, I mean in highschool). I have been trying to find a decent vid on the subject but I couldn't find it in my language which is Turkish. This vid just saved my life for real. The final exam, here I come! Thank you for the vid!

The largest organism in the world is actually not a redwood or any other plant. It's a fungus. The giant honey mushroom in Oregon.

I think it’s actually the Jeffrey pine that’s scented. Usually the areas where ponderosa grow are logged and the Jeffrey survive because they shouldn’t be milled. They are too flammable. They are almost identical. Almost.

conductive tissues take food and water from one part to another meristems create new growth, support leaf leaf gas exchange occurs waxy outer layer cuticle in epidermis, helps prevent water loss cells that make dermal tissue are parenchyma negative pressure inside the xylem as water evaporates which draws more water upward collenchyma help hold up plant body ground tissues have chloroplasts glucose is loaded into sieve cells (phloem)

It would be great if these came in a downloadable audio format... Like a Podcast. Great review for when I'm biking to school or walking the dog or even just making lunch in the morning before a big test. Cheers, Anne-Marie

this immature white man demeans Biology by presenting lessons in Biology in such a geeky and moronic manner! he should be taken out and made to collect garbage instead.
Acount Faker (11 months ago)
this "immature white man" as you call him (why you need to bring race into the equation is beyond me) makes Biology easy to understand and relatable to not only the youth, but to all those who are not advanced in biological terms yet. I would rather that biology be taught like this in schools, so students can understand what they are learning, than just forcing them to repeat the same words they do not understand in an effort to memorize the work. This teaching style also makes the subject interesting so students are more likely to do self-research on related topics that they do not yet understand. Sorry I know this was posted 3 months ago but I, as an upcoming biology teacher, do not agree with your conservative views as there are simpler and more effective ways to carry over information to whoever needs to receive it . Personally I think this "immature white man" is nailing it.

Great video as usual, but isn't a huge fungus in Oregon the largest organism in the world, not a redwood tree? I think you said that in your fungus video.

Unfortunately he completely neglects fungi when making amazing claims about plants
Kyle Fahey (1 year ago)
2 CORRECTIONS: 1. the big one- plants have 2 organs! the shoot and roots. leaves, flowers, tubers, and others are modified stems (Yes even the flower, I've spoken to my professor with a PHD in Plant biology and my professor with a PHD in Horticulture) roots have meristems as well as shoot meristems; known by most as the Shoot Apical Meristem (SAM) and Root Apical Meristem (RAM). I'm from a botany class, so maybe I'm biased, but if we're gonna teach the kids all the complex organ systems of animals then we better teach them the 2 simple organs of plants. other than that, good work, and never stop making mistakes and improving. B- for getting some stuff right though.
