Photosynthesis: Crash Course Biology #8

Spread The Viralist



Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we’re pretty fond of as well.

  1. You have good material but you speak so fast and with so much accent that it becomes super hard to understand. Videos should not be just knowledge loaded but also user friendly.

  2. I am from India , its felling good to see vedio like this I salute your work and making content like this having no wastage of time and with fun learning has become easier thanks a lot.

  3. "Or more probably, you want to do well on your test". Yeah pretty much

    Edited: 8 years old and A Level biologists are still using it to teach themselves photosynthesis. You're still a freaking legend mate

  4. I came here just looking for plant knowledge for my Herbology exam but…is this Hank Green??? Like VlogBrothers???? As soon as he started talking I got feels.

  5. I remember making a model of the chloroplast for 9th-grade biology and I made it of mint Oreos, green-dyed vanilla frosting, Chocolate frosting, sprinkles, and tableware. It was everyone's favorite because we got to eat my project.

  6. I really have a entrance examination and we have this and im so nervous im kind of a slow learner pls help me understand this

  7. Hi! I am trying to grow a kalanchoe pink butterfly from the babies. These have a VERY low succes rate due to not having (much) chlorofyl. Would adding chlorofyl water help? Or would the plant probably still die? Or would f.e. plant sugar water help?

  8. Here’s a quick way to learn I think nvm no but anyway If u join a server and some one was talking bout photosynthesis yeah that’s me anyways photosynthesis is a process plants use in order to get food they use water,sun,minerals, and carbon dioxide to make glucose a type of sugar they can eat or store for later
