Onion Cells Plasmolysis

[kfizzleguy]

Mr. marx???? lvl 1 bio??

[qaidaniel]

Woww2, this is awesome :))

[theKgaines]

this so just helped me with my lab report thanks a lot

[sheshahari]

how did you do plasmolysis while microscoping it?

[unfuna]

@sheshahari You put drops of the salty water on one side of the microscope slide and then you take some paper (a tissue for example) on the other side that absorbs the water under the microscope slide so that the salty water is drawn in instead.

thank you so much!!

[coffeecat14]

i dont get it.. is the purple stuff the solution?

[sing5sing]

does anyone know what is in the empty space? o.O (between the cell membrane and the cell sap)

[MultiGoban]

@sing5sing in there there is nothing... ( no molecules )

[sing5sing]

@MultiGoban really ? i thought it was the liquid or something o.O

[chunli06]

what would happen if you were to place these onion cells back into water if you already exposed then to the hypertonic solution?? would it revert back to normal or stay the same

[Sofaaaaaas]

@chunli06 I think it would revert back to normal since the water is hypotonic relatively to the interior of the cell and it tends to move down a concentration gradient (don't forget that what matters is the concentration of solutes) to re-establish the balance between the cell and the environment

[daveheadugly]

@Sofaaaaaas Crazy Sofaaaaaas is right. Simple osmosis is that water follows higher solute concentration. Don't you think he might actually see turgor pressure if in a hypotonic solution? Place it in an Isotonic solution and that should be the cells natural state right? Or no???

[wiabel]

@chunli06 It also depends on whether or not the cell itself has been denatured, because then there would be no way to re-establish stability in the cell.

[MCKayNine]

What a bunch of fucking geeks hahah

[SuperMastermindx]

@MCKayNine stop being such a bser and gtfo. god i wish i could do that to you it would be amusing to watch the writhing and screaming

[Debuction]

@MCKayNine at least we will not be working at mcDonalds when we're 24...

[KarizzleLondon]

Wen the membrane pulls away, what is the emty gap filled by?

[kekons23]

are guys from okemos high school?

[WhatElseExceptNature]

I just learned in bio that plasomlysis is in a hypertonic environment. But I also learned a cell will shrink because water is moving out of the cells. Why don't the cell shrinks...?

[Angelwings121]

that is SO COOL!!!!! omg !!

[susake10amstril]

OMG!

[nwiley619]

I have the worst bio teacher ever, we didnt even study plasmalysis and she puts it on the review sheet What the fluffy bunnies!

[ykcamseyer]

so... it attracted the water out of there?

[ybidiotic]

@ykcamseyer since the environments concentration of water is lower than the concentration in the plant cells, the water will move out of the cell by osmosis. Water always moves from high to low concentration

[WhatElseExceptNature]

@ybidiotic Nice answer! Clarifies what I learned today!

[gmdchanar]

i hve seen this in my school lab

[sandaranable]

i had seen this b4 in my school lab...more or less..

[zednanreh90]

Awesome! I made something similar in a class, but i didn't see this.

Thanks for this video.

[sandaranable]

yup!!its proven now

[TheILJ]

awsome

[lobstaboy79]

I LOVE IT!!!!!! IT TURNS ME ON!!!

[rcc400]

We did this in class last friday. :) it was amazing.

[ErikusRaumo92]

wow, cool to see it in action :P, this was much better then what we saw ^^ the lab fail alittle becous we didn't mix the water and the sugger right...

thanks :)

[jenniferxxhobag]

this is amazing ! :) it's amazing to watch as it happens.

[shniz09]

this is great! i missed this lab in class and i'm glad i get to see it. It will definitely help me on my bio test. ^^

[scrubbucket12]

omg this was cool

[BombedPotatoechips]

GAWD!!! This saved my science grade!!! x.X

[sandaranable]

oh really..its sved me too

[mayli775]

my science teacher showed us diz at skool

but i dont lyke science

[WhatElseExceptNature]

@mayli775 Science is the best!

[heartcorexcaseyy]

our science teacher showed this to us. it's really cool.

[kimmybshaw]

Great for NYS lab on diffusion and osmosis. Thank you!

[eunsoo927]

wow :) thx!

[maureensullivan]

Nice video, I think I will show it to my class!

[WhatElseExceptNature]

@maureensullivan My bio teacher showed it to my class. Wait, are you my teacher!!!
