Thnx very much mam/sir it really helped me very much I watched this video once and everything stuck to my brain permanently now no need to read things from book 😁😁😁😁👍🙏🙏🙏
How does oodine turning leaf's part black and blue indicate photosynthesis there? What's the connecton? Narrator missed writing the imp points about why only methylated water and also role of iodine in indicating photosynthesis.
By the process of photosynthesis the starch was formed , so we can say that if the part contain starch it was gone through the process of photosynthesis.
Chlorophyll isn't soluble in water. It is soluble in alcohol, when boiled. We want to remove the chlorophyll so as to see the iodine marks clearly at the end of the experiment. Hope you understood.
If you still haven't got the answer then read this..... The part of the leaf is covered With black paper in order not to let it be exposed to the Sunlight.....Thus We can conclude sunlight is needed for photoshynthesis as in the last we have observed that only the part of the plant that is exposed to sunlight turns blue-black in colour(The part that is not exopsed do not change its colour because photoshynthesis do not take place)........
Due to keeping the plant in dark room starch consumed by plant. If we test the leaf with iodine total leaf does not turn into blue blak colour due to the absence of starch in leaf. So we must keep the plant under sunlight for production of starch in leaf. After that only result come perfect.
When leaf turns into pale white we can easily identify blue black colour at the time of iodine test. So before going to iodine test we should boil the leaf in spirit for removing of chlorophyll.

easy way to understand that the presence of sunlight is also essential for photosynthesis. Thank u mam

Very easy to learn excellent sir
How many of you are in class 10th....
2021-22 batch.....
3:07 Well, u don't even spread iodine to the whole leaf 🙄🤔🧐why!?
I have no words to explain that how much you helped me pls keep it up sir loved it 💖✌️..
Sir you have helped me thank you
very good experiment thank you
2:57 But, I noticed you didn't applied the iodine solution on the left middle part, Isn't it? It's a bit confusing
Yes...
What happens if we apply iodine solution in the middle part?
Sir, please can you say some precautions about this experiment, and thank you sir

Will a plant still photosynthesis in indirect sunlight?
Im planning for aquatic plant inside my apartment and i lack of space

Please watch this video for all u doubts..."To test the presence of starch in leaves" ruclips.net/video/ruozuVJMuFA/видео.html
Best representation of an experiment I have ever seen ...
Well done
Thank you
Thank you mam explain for this experiment

Thank you so much..I understood the concept ❤
Thanks madam
Wow... Superb

I want many video
Very good teacher and video
Keep it up
Thanks ma'am :)
But sir, rather than indicating that the part doesn't process photosynthesis, it indicates that the following part doesn't contain starch.
exactly. the fact that it doesn't contain starch means that the leaf hasn't photosynthesized.
By the process of photosynthesis the starch was formed , so we can say that if the part contain starch it was gone through the process of photosynthesis.
Thank you so much sir
Besides we can remove chlorophyll by simply boiling the leaf in water then why to use alcohol or methylated spirit?
Chlorophyll isn't soluble in water. It is soluble in alcohol, when boiled. We want to remove the chlorophyll so as to see the iodine marks clearly at the end of the experiment. Hope you understood.
Thank u madam I learn easily and I understand easily
maam please reduce your english errors
True
Very good
But while boiling the leaf in water we have to add alcohol in test tube*
Methylated spirit is alcohol
Thank u ....
It will helps me a lot👍👍

Thanks mam it's easy to understand
Why is it necessary to boil the leaf in methylated spirit bathed in water?
Why we used black chart?
If you still haven't got the answer then read this.....

We can use any coloured chart but use an opaque one
thank you sir and ma’am

Please give your phone number

Thanks
Thankyou maam 😇
3:00 may i know why leave the middle part?
It’s the colour of the iodine solution
If you see it carefully it was in dark brown colour not bluish black
Which app is used to creat this type of video
Very nice
Extraordinary work......

Why Black paper is only used
Best option for stop sun rays

Thankss
It's practical

But why to remove or dissolve chlorophyll?
When leaf turns into pale white we can easily identify blue black colour at the time of iodine test. So before going to iodine test we should boil the leaf in spirit for removing of chlorophyll.

Sir I think 3 point is wrong
What are they?
Take a glass bottle and insert half of the leaf into it
The clip is hurting the leaf
Excellent sir
Good explanation and very easy to learn
We should not boil the leaf no
Can we use any other colours paper
Yes we can use. Any other colour papers also but they do not transparent only opaque.
