Potato experiment | Osmosis | Biology

In this experimental set up 3 potatoes - 2 raw and 1 cooked are used. All 3 have a cavity and are placed in a tray of water. One of the raw potatoes and the cooked one have salt filled in their cavities. The cavity in the other raw potato is left empty. When the potatoes are observed some time later, the salt in the raw potato is dissolved in water, while the salt in the cooked potato is still in the solid form with no water. The 3rd potato is without water. What happened here is like this. Because of osmosis, the cells of the potato surrounding the salt filled cavity gave out water into the cavity. This water is drawn from the water lying in the tray. The cooked potato cells are dead and so do not undergo osmosis. So no water is drawn in and the salt remains dry. In the case of the 3rd potato, as there is no salt, the cells do not develop sufficient osmotic pressure to draw in water..

I was supposed to do this but i forgot and it’s due in half an hour so thx

[rajasubalakshmim]

Thank you so much sir I was really confused with this potato osmosis topic . That is a question in NCERT book but I was not able to understand it .
Your explanation is a really very clear .

[laxminarayangautam]

and the style of explaining is also good

[Bio-logicfronteiras]

Very creative experiment ! I will also make this with an unpelled potato to try to demonstrate the importance of epidermis is preserving plant tissues from dessication ! Thank you for sharing your knowledge !

This is a great demonstration to help explain salinity in plants.

I have a science quiz tomorrow this really helped!! (It's on cell structure of the plant's and animals) Anyways thanks!!

[joanmouafo]

thanks bro that helped me to answer my biology lab too

[induwalia]

Thanks so much you saved my life . I took all screenshot from ur video and pasted them in my project😂. Thanks bro

[santricejarrett]

Thanks so much this just helped me with my science sba

[kellymartinez]

Does the water added in the bowl, warm or room temp.?
Thank you in advance!!

[godmadegeo]

Thanks for the experiment this was very informative

[animeweebuwu]

Thanks a lot bro for the videos now I'm going to become a scientific man!

[danielbassey]

Nice and helpful with clear explanations

[apuchuuu]

Thank you for the educational video it has helped me alot

[prabhatsengupta]

Thanks for your experiment I able to understand osmosis clearly thank u so much sir

[m__shakes]

thnx
I have to do lab at home and i got the perfect experiment for it

[sachinkewlani]

I have to do this in science exibition tomorrow thanks this helped me alot

so soaking potatoes in salt water will draw the water out from the potato? I was thinking, and this is strictly for cooking purpose, is there a way we can take up brine solution/ spice water in the potato so the inside gets spiced and salty?

So, I left potatoes in a bowl of water for a few days and forgot about them. When I rediscovered them, the water was all gooey and disgusting, and only the skins were left. Why did that happen, and what's the gooey semi-liquid?

[shanvisheth]

but what about raisins they still take up water when kept in a hypotonic solution
