12th Biology Practical | How to Write Biology practical In Exam || viva 30\30 marks #a2zpracticals

Sorry for this I know I'm very late The live event starts at 6 o'clock and will be over at 7 o'clock. It's being delayed because of a technical issue. Just a little bit, that's all My main request is with you Okay so Hmm. a lot Just speed up a bit and keep going Pata pata, come here, all the children theke Strategy Bata Duke What all do you have to do? theke Yes All the children have gone. Yes The ones who have exams are the biology students. Two people have already arrived. Yes Please Join the sessions now Thank you. Okay Let's take a close look. Let's take a look at some questions first What do you want to cover up? Where are we going? Come here, all the children Okay, look here That is the question paper. Juki provides hota hai theke Okay Why isn't it working? one minute Hmm. I think all the children will have finished today. you theke Alright We are starting these sessions now. Okay We watch all the children carefully. Okay All of them are ahead. Alright Well then, look here you know, basically Your question paper is here. So, in some format, you... They can do it. but the format of the question Exactly the same thing happens theke Whatever is written there Here but All questions are compulsory. not compulsory yeah How do you see it? What do you get? First, let me begin Look here potato osmometer You're joking, right? All the children are fixed. That's how it is with every child. potato osmometer What exactly is to be done here? I will tell you How much do I need to write? yes, practical You get four marks. sketch label diagram 2 marks 2 marks per performing a practical Okay It's the second one, I have it with me Not with this one Even plasmolysis Who are the people who detest? If given, it would be fine If not given No problem. theke but this potato osmometer It gets fixed. I am the one who is both of them I will explain. Or that last one stomata stomata of You must know How do you do it stomata of like the back of the leaf You're welcome and him/her to strain magara me dalke microscope me How do you arrange them those things to you You must know I will show you. how to use a microscope You are adjusting Okay Clear. So these are the questions I can meet you The third one and This question number one me There is so much more and more. but whatever your questions like if your teachers One question What will remain? That's the same question He will stay as a diya (lamp). Yeah, that's right, that's right He will remain as a diya (a traditional light or lamp). Test me anyone at all It is done. from this What is doosra? 3 marks It is an experiment. where not What do you want? It is a flower. viscous flower his/her yeah His name is yo ts It is happening like his/her who It is the ovary. his me ts cut it It is prohibited. flower key niche ka part Oh, no his cutting it after cutting usme 5-6 chamber It is appropriate. his/her/their (depending on context) represent His T.S. Show ts of the ovary I'll show you the main one previous question paper quit toh if only you have Shown toh 2 marks for for performing It is proper. oar 1 mark for for writing last one yo first more important hi wo spotting You directly 10 marks ka It is happening Main aapko spotting old man chart Dunga you in it you can do it hi do line for writing a mark milega do line for writing a mark milega do line for writing take You a-j 10 spotting 10 The project will be submitted, and it carries five marks. You will be asked two marks' question on any P experiment And in Las, they will review your journal submission, which has three marks on it. Marx Experiment Speak up, after the Ghatari Tari, what remains? This gives you the burden of carrying the fire within the Petri Varthi. Now there will be a hole here, and you'll strike a pin here, won't you? A pin. Now, the solution that is filled inside is hypertonic. What is it? Hypertonic What exactly is hyper tonic, kid? So, hypertonic contains a solution of water plus sugar inside. Even if you write "water plus salt" instead of "salt water," it will still work. And the one that remains outside is the normal solution. You can say "low concentration" Or are you speaking nothing but water entirely? Let's keep the water sample outside, okay? And inside, they call it hypertonic. Hypertonic Okay? So what happens then? After some time, this one here Osmosis the Thooru The liquid inside has not remained. I mean inside the battery disk The liquid on this battery disc here Where does this child move to? Inside the side. And the one who has this pin, master, you have come here A pin has been placed. So after some time, if the liquid flows out So the pin goes all the way in. The labor of water rises above it. So, what happens here is endosmosis. What exactly happens here? endosmosis Now, what is endosmosis? So, where your solution is being moved Now look, after you've performed it like this Practicals and showed them to your examiner Then you will get two marks there. And after that, after that, if you have Created such a diagram for potato Look here, this is what was labeled The entire outside water has flowed inside. So it got deeply pinned So, look, rise in the level of solution I will send you the PDF. Look here, then. When the liquid rose, the pin went deep. So, which osmosis is taking place here? Come from endosmosis pin is, potato is, petri dish is There is colored water here. So, what do we call the sample inside the child? Yes, hypertonic The question is about important vibes. What is outside is hypotonic hypotonic, all you get it My point, what exactly should I write in the observation? the level of sugar in the potato osmoscope rise after the time and the solution in the The potato's cavity also becomes discolored. So, the salt on the outside of the colored one Color of the liquid solution outside He goes inside, and inside as well, yours The entire solution turns colored. What is water plus salt? Okay And it gets deeper, meaning water level It has risen, so this is just a small experiment. You'll get this fix, so make sure to check it. What will be obtained if this is not found along with it? Study of Plasmolysis Plasmolysis gives you a plant Those people, the ones who are like this This is a leaf of a plant. We peel it off from the back. Pull out the backmost leaves by pulling them. A light, thin layering appears. Remove the epidermal cells And if you see green, green It's a part, so you also keep a little bit of it. We'll extract it by pulling only the thin bag for you As if they weren't meant to be, just keep them close to you What do you need to do to him now? Sometimes after that After a little while But then after 10 to 15 minutes, only then does this become visible to you. You start seeing the wall in it. Vaccine The outer part and this inner part, this will also become visible to you The vaccine starts. It's clear, so you'll have to wait a little bit. Thick for plasma lysis You'll need to wait a little while before it starts forming here. Now, in this microscope, you have to look at what's placed here—this one, you know, the one that's called a "nau" You can move the microscope up and down with this. Here are two lenses provided to you, please take them. Like a 10x and a 45x This screw here is a fine thread screw, correct? From this hole, we get the image, from this hole First, adjust the IP image by moving it up and down properly, okay? Now, look, if you don't adjust this, and you don't adjust both of these, then if you just slightly turn it, it won't turn at all. A slightly sharp sound comes out; this will be a very normal sound. Then we realize the microscope is fixed now; after that, we can move it up and down to examine it properly, and this little screw is the fine adjustment screw. So you won't speak to me, nor will you give me the potato osmoscope. After that, the child made this promise, the one who went away, this one. Darth remains. Keep taking the leaf, keep taking the leaf And the leaf behind you may be in the form of a peel. It remains constant, absolute oiliness It remains to start the same oil from the beginning. Allah has given it. So, the animal is called Dikaga. What line did you nail? Now I will take you to Kosher Number Two, where you have to perform the overi tias. If you've done the overy's tie, the ovary will stay completely inside the hibiscus flower, looking like this at the bottom part If you keep doing the over-tying, it will look like this in the lower part. Just learn these things a little bit and then go. Understand that exactly this will appear in your exam Exactly this will come, it will come just like this, please take a good look at it Watch the video two or three times, then go to bed later at night. So I've also asked you these promises/questions What will you do at its center? How would you create ITS? Biscuit blossom, I'll make it long, I'll stretch it We will tear them apart, we will crush them, we will annihilate them, we will destroy them. We will pre-inspect its chamber. Superot in hundred eml, you water, yes, you keep it, you take a little bit, okay, and what you took out from here Now, don't you see something like this image? Look at it under the microscope, then you'll see something like this. It will appear in this, but sometimes it starts intermittently, sometimes continuously. A few moments of family gamut begin to appear, and then they converge right here. So, you'll see the tube after a little while. So if you showed the tube to your examiner So you get full marks, okay? How will you get full marks? Poolan Brinj Germanization is very aged. So you showed the Poolan Brinje Germaneshin microscope You've got one mark there. And the child stays with you, writing two marks together. Alright? Look here What will you create, a diagram? And this pool tube display And mail gametes and non-mobile Is it okay to show these gamets? Showed it to you if you've already leveled up You'll get two marks here, right? It's extremely urgent. Next one Let's move forward Papillary density by I've already told you the coordinates. In this, we verify the profit of the profit plant here. Even if I don't understand, please just watch the video a little more carefully. Comprehensive soil sample up to the piezometric level and soil type What do you mean by type? I'll tell you Where will the handbook be kept with me? Like, what kind of type is Sandy? So the thing we'll see there is whether it's acidic, basic, or neutral. We'll also take a quick look at those things there. Just don't worry; I'm making everything available for you. Tons of Khao, this promise, this is HAH a to study the sample of water may bring the pH in clarity, there is a one-liter T-type container, and this is it What is the pH of the water type along with the soy type? How is it, and what is the type of Shoyl? These two To be given while simple for pH and their type. Look, these were What does the soil sample look like, and what is the type? I will tell you clearly. You will be given 2 soil samples. If anyone gives me two soles, how should I make the bill? Please tell me. Put the bill paper here, correct? If the bill paper is in... The reading you receive will appear in a color like yellow and orange. So, how is his reading... let me check the pizza paper, isn't it? Look, the pie is peeping like this. They might also provide you with the basic one. Wherever you go, you'll find pepper and paper there. So, if the pizza paper stays in your blue, kid So understand what will remain ours Basic and Pizzapaper, if your red is You'll find out just by trying pizza paper. It will look a bit thin, but the Basic one, which will keep the Annuals, will be fine. If it's a bit too sour, it'll look a bit acidic, and if it's a bit too bitter, it'll appear a bit bitter. I need to write something basic, a little bit of a mess, right? The conference, inspiration for an age, must explain whether we can make it permanent. No. Look, you're going too far away from the acidic water, and you're also going too far away from the basic water. You will get the tension, meaning recorded form, okay? This is the Piz Op, this is what we will give. What are you saying? We'll give you sand, but you have to figure out its price. Okay, price, paper, insert. The garden's soil is suitable, yes, the root side soil is suitable, and not point, meaning when it dries up, then the soil there is taken, so this This is brah, this is brave, this is grey, this is brah. How is Exixor? These are clay, but slightly rotated. In the rot side of the cement, all the more will be mixed, right.. Soomi's cell is a bit clean, but it's still dirty. Look, what is this stubbornness of ours? It's Clay. The percentage of Kyonggo Sete Clay is higher. The percentage of Salit is this. The percentage of Saind is this. So, what do we have in our presentation regarding the texture? If it's an open presentation, what else can we write here? These are the best fertilizers we have, right? Okay, let's go. Then these are some samples that will be given to you Just remember this: Croft Field A stubble field means the area where rice, wheat, or other crops are grown and then harvested. So, in his case, the brother should have less sand. Both sand and silt should be low. And Clay, you will be more. If they give it, we'll let you know who is giving it. Alright, let's go Now, listen carefully I have explained all the experiments to you, kid, right here. Now comes the part about sports. So if the child has started to show signs of sportsmanship So, I will definitely bring a sports item to your group tomorrow. Don't vote for any farmer candidate, you I'm providing you with a complete exclusive sports content. I'm showing you, look, he's gone, brother. Come on, Simsim, come on, Simsim. Okay, here it is. I'm going to give you the complete sketch of the osmometer for lac potato. Whatever I'm giving you here, show it exactly as it is, show it exactly as it is, just like this. Look here, you're putting the pin in the wrong place. See, there's a colored liquid inside. Hypertonic solution is outside, hypertonic solution is, inside the liquid The liquid will enter from the side, and the liquid will rise up over the pin. Alright, just take a look at those things; you'll definitely need to make a diagram. Thirty overs, you need to show me the structure of the over, right? Didn't I tell you what the center axis is? What are locules? And what is a spectrum? Spectrum, the line that divides each individual chamber Sakho spectrum bolte hain, theek hai? After that, if you want flower Come here and show me this arrangement—what do we call this? I also wrote it; look, they call this a calyx. The corolla speaks, right? It's called the corolla, not another. xymnosperm, endryosperm, okay? It's clear, Tea's Over here, you can see it right here. Alright, kid, it's exclusive and constant, so please, I request you, for anyone's sake, don't let this happen Don't share, okay? If you want to share, I'll give it to you. Look at this, pollen brain germination, so this diagram shows you It will be made, right? It's just right for you, Okay? This is the pollen cube; the male gamete goes from here, right? So you will make this, here are two marks for the examiner. If you show me the slide, I'll give you one mark, okay? It's clear, look, you'll see such tubes inside the slide, You will see tubes like these, tubes in various shades of yellow. Clear, if you need this, just comment me, kid. I'll add you to my group, there shouldn't be any lion among anyone. This is the quadratic method I just showed you, right? Look, regarding the pH of the garden soil, just measure it using pH paper. Loamy, loamy, you know, a good soil is one where fertility is high, Lomi, I'll tell you what happens. Sandy and Clay get mixed up, and the percentage for both is equally balanced. That's great, Lomi, this is indeed Clay. If you go in the middle, you'll find Sandy. If you place pH paper there, it might turn blue, indicating basicity, okay? Do these things first, then check the rest; you'll be given a water sample like this, just check it out. It's garden soil, roadside soil, and beach soil, okay, you'll be given pH paper like this. Alright, check the pH and write down the value that matches your pH indicator paper. Is this the best or not, tell me, kid, is this the best or not? Okay, so this entire content is exclusive. So you came after paying, because I had to give this to you, okay, I put in this effort for you. Okay, so if you read this PDF, the children will surely enjoy it. Alright, let's go, now I told you that, TR, yes, vive, hey, spotting, look at this, Yes, Martin Poloji, okay, it's about insects, so please write any two points from this, a child He knows what's wrong with him, a child knows, send me to the group, you'll get it, you'll get it, yours You know, if that child goes inside and reads his spot, he could get 10 marks, right? That'd be great for the child—his first spot, wind If the spot corresponding to B appears above the chromatography, it's fine. Just read any two points from this, any two points. If any spotting appears on the leaf experiment, please read any two points from among these. Okay, this is all the plant, okay, if any spotting occurs above the plant, deal with it, okay, Babul, what can we write above this babul? Non-succulent, zero fights, okay? Spines protect it from being eaten by animals; if animals try to eat it, the spines provide protection, correct? Next, what is it, which one is this, tell me, adaptation, morphological adaptation, about which one, yes, apunshia, okay, if you can also point out two from these, okay, I'll make sure you do this, first let's see, okay, where were we, I was telling you about spotting, the child, spotting is essential, if you're going to do anything, it's your spotting that matters, right, okay, let's go, so for those children who have ten spotting, their details will be revealed. Half marks are awarded for each point. V.S. of Bastula, this child has received it, along with V.S. of Bastula, okay, okay, so in this manner The content is this, what you need to do, okay, you're looking at this, this bagging, tagging kind of thing, will come in spot E, right, okay. It's clear, some spots of F will appear, some diseases will come, so you have to go through any two of them. You have to study the points, just one more thing: if your college professor has already told you which topics are important, then just study those. You can keep the water inside yourself; look at this, this kangaroo red, okay, so any two brains placed on top, you have to go through any two points only, okay, so that was all. Play, kid, first tell me—please don't share this with anyone, okay? This is for you. Here in this Pedia app, your entire biology practical is hidden. So, go ahead, do it. I've told you everything here. If anyone else... Just chat with me, I'll clarify everything for you there. This video is for you. The link will be returned to you, and you'll be able to access it anytime, permanently. That's fine for you. What kind of lock is it that is still locked? Show me what you're feeling if you feel like it I must be playing jute ball. Look, I used to go as far as I was thinking. Show us, we will remain open with you. Okay, let's go.
