Osmosis | Membranes and transport | Biology | Khan Academy

Osmosis of water (or any solvent) from area of lower solute concentration to areas of higher solute concentration through a semipermeable membrane.

Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

I love how he says the same thing twice, I really need that

[marandapalmer]

Thank you! I am a junior in college, and I have always a hard time grasping this concept until I watched this video!! After 14 years of school, I can say I have learned more from youtube than most of my teachers.

[carolinestrecker]

I just enjoy listening to Sal’s voice.

[selfreliancelearning]

"SAH-LOOT" He just kept saying it and I couldn't focus on anything else!

You should have 7 billion subscribers. Your organization helps so many people!

[RachelJayn]

I'm watching this the day before my finals haha

[venkatapranavreddyd]

This video helped me a lot in my exams, thanks a lot Khan academy for publishing this video and .I love your teaching style

This is a beautiful example of Osmosis, I came out learning a new concept.

[ohheyLeighannn]

We are learning about osmosis and osmotic pressure in school... all of this is floating right by me 🙃

[mattfreedom]

Thanks so much for your time and efforts Sal!

[michaelcapponi]

this is such a good resource. i'd rejoice if it were merely one, let alone thousands of videos

[farahmahdi]

الشرح يجنن ، مع اني جبت 100 بالاحياء لكن بعمري مجنت فاهمة الماده بهالدرجه ابداع والله❤️❤️❤️❤️

You can demonstrate osmosis at home using Umibudo (sea grapes.) The umibudo are packed in super-salty water, which makes them shrivel by osmosis. When you rehydrate them in fresh water, you can see them swell up as the water rushes in by osmosis. Osmosis before your eyes!

THANK YOU.THE VIDEO CLEAR EVERY CONFUSION I HAD :_:

[error_in_the_matrix]

i am here from 2020 to say thank u <3

Overview of the entire thing (for bio students)
High h2O concentration goes down the concentration gradient and where the solutes go the water ultimately will follow by probability and then remain there due to them being attracted to their full change.

Probability: Water molecules have a higher chance of crossing a semi-permeable membrane than larger molecules I.E. sodium, due to there small size.

Thank me later

[biologyofolevels.]

thanx brother. you solved my confusion.Your video is very helpful.thanx bro.keep it going.

[maryamsediqi]

You are the only explainer which I don’t know how the minutes are passing, awesome 👏

[EvaldasPe]

Water model have moved beyond "molecules bouncing of each other" and "water molecules that (supposedly while flying by Na+) MIGHT stick to Na+". Why is this "billiard ball" model still taught?

[calebkimutai]

Nice work done there you have really helped me learning osmosis, good work for your organisation and God bless you
