Study of suspended particulate matter on leave || 12th Biology Practical @a2zpractical991

Now, what should I do with it? I'll observe it under this microscope. And I'll check whether there are some particles or some pollen grains or similar things visible in it. So today we have to find those very particles And find out, buddy, if I wash a leaf in the wash tub So will particulate matters be present in it or not? Hey kids, how are you all doing? So, kids, let me tell you about today's experiment It is Experiment No. 6 of 12th Biology. Where we will study suspended particulate matter It is present in our air, but at two different sites. What it is, we will see. But you must certainly know its purpose. that basically we will take any such substance Whatever matters, is present. But what else is present with matters? We have to find out that very thing today. When there are some particles present in the air So, what do they do with the air? Whatever objects we have Those bats go over his head. So today we have to find those very particles And find out, dude, in the wash area If I wash the leaf So will particulate matters remain on its surface? No or yes If I don't wash the leaves above this point, How will that leaf remain? We will observe these things under the microscope. And those who conduct experiments very skillfully What is the experiment number 6 in 12th biology? So let's start this experiment in a very exciting way. So, for the child, we will take two types of leaves. I've picked these two leaves for you. We will wash one leaf and keep the other leaf as it is. And let's see what we find to look at We wash a leaf very thoroughly. We'll wash this very thoroughly. And we will not wash a single leaf. So that we can see what result it gives Your experiment has already started. which is your Experiment No. 6 Alright, so we have this wash leaf here. And now, what am I going to do? I'll take this on this glass light. What should I do with this on the glass light? And I'll cover it on top. What am I supposed to do with this now? I will observe it under this microscope. And I'll check whether there are some particles or some pollen grains, etc., on it. What do you see in this? Ala, this leather is completely washed already. So it's very difficult for such particles or peaks to appear Alright, kids Let's go, but what are we going to do? We'll observe. So nine is the wash label. Now, kids, what should we do? Should we take another leaf? And what is this leaf for? I haven't washed it. So if I haven't washed it, the child So, particles will also remain suspended in it. We will also see what other things remain present in it. So let's take a look at this, then you You have to do the same with glycerin. What else needs to be done? Add it. What are we going to do with this? We'll just give it a light smash. And right now I'm on the cover slide I'm putting it here. Suit particles Now we will look at this. So, kids, what did you all show? We had to take two leaves. for comparison with As I had already wiped out Leaf. Whatever it was, like Polan grains and so on Whatever particles of carbon there were Whatever matters were present They have all vanished. The leaf that I did not wash So, there were so many things present. You have seen it in the photo and also seen it in the video So, to compress it, we'll have to take two leaves. The court will not understand us. How do you find this video? How was your Twelfth Biology Experiment 6? Where we are different in different areas, how matters and how pollen grains They are present on top of our leaves, etc. We have done all these experiments today in this practical. Alright, and what was done with the handle of this microscope? And until now, we've been telling you about this video and what Rajinikanth's own subtext is, the subtleties of ATJ's practicals, the subtext
