Video Summary
AI GeneratedThis video provides a step-by-step practical demonstration on how to observe stomata in a leaf using a microscope. The presenter explains the function of stomata in gas exchange and guides the viewer through the necessary materials, the process of extracting the epidermal layer, staining with methylene blue, and the proper technique for preparing a slide to avoid air bubbles.
So hello guys and welcome to my channel, friends
I'm showing you Sukhla, and you're seeing A to Z practicals
So, friends, the experiment today is the one that
I am starting my biology experiment.
So basically, what are we going to observe in this biology practical?
He is looking at this stoma.
What does this stomata do? It allows gas molecules to
What does a stoma look like?
What happens to it? Structures happen.
How to do its practicals
How will the results come out?
How to set it up
How did you show up in the Stometa exam?
that he should get good marks from his examiner
I will tell you all these things.
If you like it, please share it with your friends.
Let me show you how to start the experiment.
To carry out this experiment
You will need a dissection box.
What all things are going to be applied here?
You will receive a dropper.
You have taken a watch glass.
Here, take a pair of forceps.
Cutting it short, then, something like this
Take a glass slide
And we'll take one cover slide as well
Here is a cover slide
to perform the experiment
A leaf that will stick to you
The epidermal layer that we people have
Those who do, those who remove
forceps, glass slide
And a watch glass will be attached, a dropper will be attached.
And we will use some needles.
And here, there is a cover slip in it.
What does a cover slip look like?
There is a lot of confusion.
Use this very comfortably.
And I am going to use chemicals here.
That is methylene blue.
We use this to achieve very intense colors.
And what it becomes is very diluted.
We keep it diluted for this reason, otherwise
That is our stomata
So many of these have methylene blue
Chemicals are present there, it will go through.
What do they do with their mortgage?
What we were doing to ourselves
What are we going to do here?
We are taking a leaf.
What should I do with this leaf?
I'll just lightly scratch from above.
So let's take a look
Here, you have a light one
It was all very light.
That is what we must take.
And that is what will continue to move forward.
But you have to follow this.
For this layer
What do we need to take?
I'll cut this.
What should I do?
But what about some other matter?
I take the midline blue from the dropper.
Thiki Vojzak Ash Khandar
Hey, I've got that in my possession.
I took Mithiline Blue and those pills were effective.
Whoever is the owner of this lead, what would I do with it? I'd just dip it.
Apply one to two drops here and rub it in.
Then after that, what about you
If you've removed the pills, then the epidermal layer is fine.
I'll do the upper layer here and keep it here.
You always keep it very well placed, just right
There may be bubbles in the Adharvaij, that's fine.
So, how to keep it, let me show you here
It is part of the Tike Bawar slit; touch it on the glass slit.
Just place it gently here, that's fine.
You'll see, the entire air bubble comes out.
And everything that remains, isn't it?
Even the water carriers come out to meet you, right?
What should I do now?
I'm checking how it looks on me.
I have made all the videos about Screw Vaguer.
And these practicals, the ones that parents are doing, are very easy practicals.
Now I'll check it here.
I'll speed it up to 10x
After that, I'll do it at 40x.
Philal has already reached 10x on Agis.
Alright
So, finally, this is what I'm showing you, the structures.
You can see it doesn't look very good at all.
But right now I'm assisting it at 40x magnification.
And I'll show you how this looks
Front, what should I do with this?
I look at it with 45x magnification.
But it takes a lot of effort to show it.
Fronts, you have to do something very important with one hand
So, strawberries suit you perfectly.
You must have seen the practicals of Stomata
You must have felt very good.
And this is a biology experiment, not necessarily a biology experiment.
You must have seen the practicals of Stomata
You must have felt very good about it.
