How do materials move across the cell membrane?


Do you want to know more about passive transport? Osmosis? Active transport?

What is a concentration gradient? A solute? How do they effect the rate of passive transport? Please respond!

  1. Its really interesting how they can figure all of these facts about microscopic cells. like how do they get all the little details about something thats sooooo small!!! Its amazing how they found so much that they can create an animation of how the functions of a cell work.

  2. i no this is a old conversation, but if pretty much all animals can mix, why are there names for only a few of these combos? arent there like a million others?

  3. I was looking at sites on the internet, and found this site: http://science.jrank.org/pages/1327/Cell-Membrane-Transport.html
    I read it, and found it interesting!

  4. i like how the vents can let only a few molecules thru and others are blocked.

  5. i love this topic, its really interesting and cool once you get the idea. i just dont really understand why molecules go to a higher concentration in active transport...

  6. I think that a solute is either the substance that is dissolved in a solution or the substance that dissolves something. I always get confused with those two.

  7. I thought that the topic of diffusion and osmosis was really interesting because i liked the way the cell membrane acted to other molecules and how it acts like a security guard.

  8. When we learn about this in school, it kind of freaks me out that what we're talking about is happening right inside our bodies!

  9. love the topic too. It's so cool!
    but the names are so fancy and eventually, there will be so many types i actually might forget and fail a quiz!!! jk.
    Cool though.

  10. (Yes, I did comment on something beside the cell and microscope games). I think that this video was very helpful in improving my understanding of the cell membrane and passive and active transport. Thanks Leslie!

  11. this video was very helpful! my sister who was sitting next to me while i was watching the video has an idea of what passive transport and diffusion are!( she is 6 years old!)
