Osmosis.mp4

This is an animated demonstration of osmosis, specifically isotonic, hypotonic and hypertonic solutions. More educational videos can be found at: www.mcsdpodcast.net

[@RaiRaiBrown]

This is perfect. It's exactly what we are doing. Im glaf these videos are available because I need to see these things. It makes what we read and take notes on much more clear.

Plss can learn me english

No. Osmosis is the movement of water across a semipermeable membrane from an area of high WATER concentration/low SOLUTE concentration to an area of low WATER concentration/high SOLUTE concentration.

[@drFabUnik]

I truly understand osmosis now that you had did your demonstration. Thanks so much for the help

[@TruthReviews]

I had watched videos and read about this but only after watching your video did i truly understand it. Great video. Thank you.

[@CCSpaceScienceCenter]

Thank you for your comment. Osmosis deals with water balance. Since there are fewer water molecules inside the cell, the water molecules enter the cell trying to dilute the solute and reach equilibrium.

[@allysonrodriguez2209]

Your explanation is the best! Thank you!

[@Goldendawn5598]

Fantastic video! My lecturer was a bit confusing and wasn't clear on tonicity. This was very helpful. Thank you!

[@CCSpaceScienceCenter]

Give us a suggestion; something you are having trouble with and we may make a video.
Thank you for your comment.

Great vid.I got this topic explained in as much as time as the vid played.

[@incontent9813]

That was really helpful for my biology test, thanks to this i got 69.420%

[@BlakeBlackstone]

Thank you.. I needed a visual perspective on this to grasp it better. :)

[@mahms012]

solute is something which is usually dissolved in water, which is always the case in living systems.
easy way to summaries and think osmosis and all the related term is, where ever there is higher concentration of solute, water the solvent, will move to the solute like its attracted to it. if solute concentration was high outside the cell then water will be attracted to solute and move from inside the cell to outside the cell.
NOTE: i only used "attracted" to make things easier.

[@curtpiazza1688]

Excellent demonstration! Now I understand osmosis!

[@user-vp4he6sd6d]

your explanation is really good thank you very much❤

[@maniskyquest]

excellent explanation... thank you very much for uploading this video.....this is very useful for me...

[@GeorgeAntonopoulosgr]

Your videos are fantastic!!!!i have a question pls....how difficult is to make an osmotic membrane with osmolarity 100-200 gr??is there something to see about this??thank you so much for your excellent work!!!

[@babiig37]

I FINALLY understand this. THANK YOUUU

[@lightpersistance]

Great! Thanks for sharing. See other instructional videos at mcsdpodcast.

[@himynameisjakeable]

Someone please reply to me as soon as possible:
For hypotonic, at @1:09 1:09 they say that "there is a greater concentration of solute inside the cell" but osmosis is the movement form high to low concentration. So if there is already HIGHER conc inside the cell, would the cell not shrink because it goes from high (the cell) to LOW (outside cell) and therefore would be hypertonic instead...? Please help

[@aneksii5769]

Higher concentration of WATER molecules. If there are less water molecules inside, that's where the water goes.

[@mhh.cuber_ofc]

means that the cell would become more concentrated..not already

[@ArealSimpsonizer]

YES!! I finally get it!! my teacher explained this to me like 12 times...but I couldn't get it... THANK YOU!! :)

[@keborn26]

beautifully explained

[@90Zook]

Helped heaps, thanks very much

[@mazedurrahman3213]

inside cell
solute particles could have shown in high concentrated form, not water molecule.

[@1malakian]

Thanks for your help

[@reyouf83]

Thank you ❤️

[@emilie4906]

Thanks :) I understand it much better now

[@Areeb296]

perfect explanation. :)

[@momowowo16]

Thanks the video help me a lot

[@kaylareed5153]

What is an example of solute in the lab

[@Mahalouker]

Sodium chloride (salt). It is commonly found dissolved in water, such as sea water.

[@farisakmal2722]

Thank you for this informative video. One thing I would like to comment is, please use the term 'mass' instead of weight, as your scale measures in grams and not Newtons.

[@grayace4702]

can I ask what is the solution in this experiment. was it the one inside the dialysis tubing or the one in the beakerr?

[@Spiritual-Log]

where is that said? what minute?

[@mariposalivre]

cell with lower amounts of solutes, not higher. Someone correct me if im wrong.

[@arezohotak2473]

Thank ! it help me alot. :)

[@abigailbossa2546]

Help me a lot

[@SimonRichardMasters]

Any suggestion that "the water molecules [enter the cell] TRYING to dilute the solute and reach equilibrium" is a teleological explanation. I precis Jacques Monod, biologist: The elimination of explanations based on end purpose (or intentionality) is wholly inappropriate in biology. Isn't it that the thermodynamic stability of the entire system is at its lowest when the water and solute are most intimately (Gibbs Free Energy) etc...

[@arkstudio5546]

Very useful

[@spastictastic15dino]

wow! This really helped... Thanks! {;

[@ratebsoltan3371]

thanx

[@mariposalivre]

i dont know what to think about this video. It says that in a hypotonic solutions, there is a GREATER number of solutes WITHIN the cell. My A&P book is saying that in a hypotonic solution there is a LOWER number of solutes within the cell. WHy would water go into the cell if the solute in cell is greater? It makes more sense, to me, that water would swell a cell with lower number of solutes becuz it wants to reach equilibrium. Like drinking gatorade to hydrate your cells. its gunna swell the

[@emilyvillatoro9729]

I understand better this video than my bio class lol.

[@raniashakeelahmed3718]

thanks a lot:)

[@akhsarbekgetoev7725]

Спасибо большое[spaseebo bol'shoe) means thanks verymuch (RUSS)

[@mamta2119]

Awesome

[@tomcoughlan6893]

THIS VIDEO IS LOUDDDDDDDDDDD

[@bbwwaaggss]

your right. this is diffusion high to low..osmosis is low to high. nice video just bad wording.

[@xokizza]

I totally remember doing this, thanks for the clarification :)

[@James-pf9mn]

my dad has a few of thos "cells" in his night stand.

[@santhoshkumer8339]

I don clear anderstand

[@syazlina2008]

The definition explained for osmosis is suppose to be the definition of difussion. Osmosis to low to high.

[@ainibrunei]

Isn't low to high for active transport? What I learned is that Osmosis and Diffusion are both down a concentration gradient which means from high to low.

[@Filipinogenetics]

+Eizz B Rusher Ner diffusion is solutes wanting to go from an area of high concentration to low concentration in order to balance out. Osmosis is water going from an area of low concentration of solutes to an area of higher concentration of solutes, again to balance out (remember our body is always trying to get in that balanced state, homeostasis). You're right about active transport also.

[@catherinevictoria3116]

hypotonic 1:07-1:35; hypertonic 3:13-3:27. thank you. it helped me understand more

[@user-bu5um3jy4l]

رجا ترجموا بالعربي

[@shreyashukla1955]

red blood cell looks yak..

[@mike02601]

this video is wrong , osmosis is movement of water from Less concentretion to More concentretion.....wrong wrong wrong

[@Priyanka-ir2tb]

thanks, why cant you be my teacher?

[@Lovingjihye]

LMAO

[@rnvanheusden3]

That's diffusion *facepalm*

[@dynamitegamer7529]

whos here from ck-12

[@omarhamid2583]

I’m only here because my teacher wants me to do a short awnser on this😭😭😭😭😭😭😭😭

[@knexandnerf]

you americans talk funny
