Hydrilla is an aquatic plant that can perform photosynthesis even in water that is why hydrilla was used.Adding baking soda during the experiment kick - starts the process of photosynthesis. Hope this helps ❤
Why does the gas moves upward and does it mean that the oxygen that is being produced in ocean will move upward and if this happens then how the oxygen in the water does not finish.
Gas moves upward because it is lighter than water. At the same time , you shud know that there is something called "Dissolved Oxygen (DO)" which is oxygen that remains in water in a dissolved for. Not all 100% oxygen prodiced in oceans escape the water, some amount dissolved in water for the aquatic organisms to use.
depending on how well you are able to remove the test tube from the beaker, a little or a significant amount of water may be present in the test tube. But that really doesnt matter and does not affect your test for oxygen.
There is still a great amount of water in the test tube and it's been a whole day since I put my set up. What do I do? Do I let it be for tonight and let it be filled with gas tomorrow?
A very wonderful experiment and explanation! May I present your videos related to green plants and photosynthesis to my first-grade middle school students?
Hello! Nice video! I made some calculations about conversion of carbon dioxide to glucose and release of oxygen. Lets take into account that 50 000 L of air and calculate amount of carbon dioxide in it V (CO2) = 50 000 л * 0,04% CO2 = 2000 л CO2 100% quantity of CO2 = 2000 L / 22,4 L / моль = 89.285 mol 6CO2 + 6H2O = c6h12o6 (glucose) + 6O2 quantity of substance of glucose = 89.285 mol / 6 = 14.88 mol weight (glucose) = n * Mr = 14.88 mol* 180 g / molглюкозы = 2,678g and as a side product it releases 2000L of O2/ How this number was obtained? According to the equation amount of O2 is equaled to CO2 = O2 = 89.285 mol/ 22,4 L / mol= 2000 L
@@TheSingtangpaScienceGuy but cant the bubbles be released at the bottom of the test tube, and they would still float up? Does it have to do anything with the water pressure?
All green autotrophic plants produce O2 as a side product of photosynthesis. Produced within chloroplasts, they eventually escape through the stoma and other open areas of the plant such as cut surfaces like those of the stems of the plants we are using in this experiment. Escape of oxygen gas through the cut end of the stems is a sign that photosynthesis is taking place in the plant.
photosynthesis is a great idea to explain how plants interact with their natural environment but it's only an idea. The oxygen in the above demo came from the NaHCO3 that was added to the water and we all know there is no NaHCO3 in a plant's natural environment! So the process of photosynthesis is a great idea supported by contrived demonstrations. However what's even more amusing is that science has not come up with any mechanism whereby the alleged oxygen produced by plants bonds with nitrogen to form an air molecule!! Science is insanely funny!!
Honestly the best video I've seen out here for this experiment, thank you! :D
POV: you are looking to see if your friends commented on this video you had to watch for school
Lmao 🤣🤣
Whose here from school
Me
I have a doubt
Why is it required to completely submerge the funnel in water
It's my last day fr exam 😂
@@KirtiJaiswal-k2r so that no air is in the funnel does not contain any air and the reading would not get any error
Me
Now i understand this
In my text book it was not written clearly
thanks
filmed well and explained clearly, thank you for this helpful video!!
Very well explained with all the steps... thanks!
Thank you so much, it helped me a lot to study the experiment given in my book 📚👍🏻🙏🏻🙏🏻
how do you design a control here?
thank you very much.. it's a complete experiment.. well done!
The best video for this experiment....awesome!!:D
Why the waterlevel decreases in the testtube during this experiment??
Am I able to use like the aquatic ferns?

Are water present in test tube after removing if from beaker for oxygen test?
depending on how well you are able to remove the test tube from the beaker, a little or a significant amount of water may be present in the test tube. But that really doesnt matter and does not affect your test for oxygen.
Can you also use artificial light (eg LED light) ?
Thank you Sir for clearing my doubts through this video
Great video! Helped me a ton!!!
There is still a great amount of water in the test tube and it's been a whole day since I put my set up. What do I do? Do I let it be for tonight and let it be filled with gas tomorrow?
Thats also not a problem
amazing experiment, really helped with my activity, thanks!
Can we use any other plant instead of aquatic plants?
Thanks man
well explanation step by step, clearly understood Thank You!!!
Instead of dark reaction, " Light independent reaction " would be more appropriate I guess.
Dark reaction was the old term they used to teach, they usually use "Calvin cycle" now. Guy is probably older and just learned it the old way

Thankyou. No problem 👍
Can I use baking soda instead of potassiumbicarbonate?
No

Why did you cut the plant?
Blud, the plant is too big
Why do we put the plant upside down? On my biology experiment we used elodea, and one question was why did we insert it upside down?
The oxygen is released thru the cut end of the stem. So we invert it so the bubbles neatly float up and collect in the test tube.
@@TheSingtangpaScienceGuy but cant the bubbles be released at the bottom of the test tube, and they would still float up? Does it have to do anything with the water pressure?
Thanks a lot. 🙏🏻🙏🏻
Wow thanks awesome demonstration
Thanks man you saved myife ❤
Nice explanation, but i dont think a pop sound comes when u introduce a glowing splint in the test tube
It does
how the elodea plant give off oxygen during photosynthesis?
All green autotrophic plants produce O2 as a side product of photosynthesis. Produced within chloroplasts, they eventually escape through the stoma and other open areas of the plant such as cut surfaces like those of the stems of the plants we are using in this experiment. Escape of oxygen gas through the cut end of the stems is a sign that photosynthesis is taking place in the plant.

Nice video, it's very helpful and it makes me wanna try it 😇
What is the splinter that you have used please? I have set up the experiment for my students yesterday. T oday I have to conclude. Please help
Burning piece of stick/matchstick etc.
@@TheSingtangpaScienceGuy Thank you!
Can u use spinach instead of that plant that u use for the experiment ?
You can use any aquatic plant.
@@TheSingtangpaScienceGuy the problem is i dont have any 😔
Very well explained
Is waterplant mandatory? Can I used any kinds of plant?
For this experiment, we normally use a naturally submerged aquatic plant.

Explained like a mast
Good explanation sir
what is the plant in the experiment? hydrilla or chara ?
Hydrilla. U can use chara or elodea or any water plant for that matter.
Can't we do this in the lab?
Answer this quickly.😊😊😊
Why not...
@@TheSingtangpaScienceGuy If the plant is not watered, the plant will die
@@shotonandroid2822 yes.
@@TheSingtangpaScienceGuy ok,thans very much😁😁😁
great video! may i ask? why the experiment is done under water?
To prevent atmospheric air from entering into the plant.
@@TheSingtangpaScienceGuy thank you so much!
Man this is awesome 😎 💯👍👍👍
POV: ur watching this for school work
fr tho
I understand very very well thanks a lot you are the best
Super explain ☺️
Thanks a lot👍👍👍👍👍
Tq for keeping video it's to helpful for of all us
Thank you so much
I have done this experiment today in our school😁😂
Will be any change when we do this experiment in direct sunlight??
You have to do it in direct sunlight.
You cannot do it without direct sunlight, photosynthesis cannot take place.
Extremely helpful 👍
Thanks 😊
Very will understood 🙂.. thank you
thank u!!!!!!!!!!!!!!!!!
Thats cool experiment
🎉🎉it's wonderful
I wish I could too do it... My mother doesn't permit me for such experiments involving flame work.. 😁
Why are we adding sodium hydrogen carbonate?
That acts as a source of CO2 for the water that the plant is in.
Really helpful ❤️
Good explanation sir.
Awesome video
Very nice explaintion
Wow awesome thanks for this video nice
But you have explained very good
