[0:00]Hello my dear students, welcome to the IMB Education. Aaj ki is video me hum kar rahe hain Class 11th Biology Cell the Unit of Life ke NEET previous years questions last 33 years ke. Is chapter ke andar total 129 questions hai jo ki hum isi video ke andar complete karenge. Agar aapne other chapter nahi dekhe to aapko I button me playlist ka link mil jayega, aap other chapter bhi check kar sakte ho. Aage badhne se pehle agar aapko Biology and Chemistry ke notes chahiye pure NCERT based for NEET exam to aap is video ka description check kar sakte ho. Toh chaliye start karte hain hamara jo first topic hai, What is a Cell? Ab dekhiye yahan se kuch question aaye hain but wo jo hai wo microscope se question puche gaye hain. Aur kaafi purane questions hai, 2006 se pehle ke hi question hai usse baad ka koi bhi question nahi hai. Toh aap isko skip bhi kar sakte ho kyunki aap jo Physics ke andar bhi microscope ke bare me padhte ho. Toh chaliye phir bhi hum yahan pe question kar sakte hain, first question hai hamara A major breakthrough in the studies of cells came with the development of electron microscope. This is because yahan pe jo hum cell ki study kar rahe the usme major breakthrough kab aaya jab electron microscope aa gaya toh hum uske cell organelle ko bare gairah ko jyada detail me study kar paye. This is because (a) the electron microscope is more powerful than the light microscope as it uses a beam of electrons which has wavelength much longer than that of photons. (b) the resolving power of the electron microscope is much higher than that of the light microscope. (c) the resolving power of the electron microscope is 200-350 nm as compared to 0.1-0.2 nm for the light microscope. Ya option (d) hai electron beam can pass through thick materials, whereas light microscopy requires thin sections. Toh light electron microscope me aisi kya cheez advance thi? Toh electron microscope ke andar jo resolving power thi wo jyada thi as compare to light microscope jiski wajah se jo hum small organisms ya fir small cell organelles ko bhi dekh sakte the. Toh yahan pe the resolving power of the electron microscope is much higher than that of the light microscope. Okay ab hamare paas second question hai, second question me pucha gaya hai A student wishes to study the cell structure under a light microscope having 10x eyepiece and 45x objective. He should illuminate the object by which one of the following colors of light so as to get the best possible resolution?
[2:25]Toh use konsi light color lena chahiye best possible resolution ke liye. Ab resolution jo hota hai according to physics yahan pe inversely proportional hota hai wavelength ke. Inversely proportional kiske hota hai? Wavelength ke. Ab aap ye batayie ki sabse kam wavelength kiski hogi? Jiska sabse kam wavelength hogi uska resolution power bhi utna hi high hoga. Toh yahan pe sabse kam wavelength jo hogi wo kiski hogi? Blue color ki hogi toh yahan par iska resolution jo hai wo high hoga. Toh agar wo blue color lega toh use best possible resolution usko dekhne ko mil sakta hai. Toh yahan pe second question ka answer aa jayega option (a). Third question hai Electron microscope has a high resolution power. This is due to the electron microscope ke paas high resolution power hota hai kyun? (a) electromagnetic lenses (b) very low wavelength of electron beam (c) low wavelength of light source used (d) high numerical apertures of glass lenses used. Electron microscope me high resolution hota hai. Resolution abhi bataya tha inversely proportional to wavelength hota hai. Toh yahan pe very low wavelength agar electron beam ki hogi toh utna hi jyada higher resolution hume dekhne ko milega toh isliye third ka answer aa jayega option (b). Next hamara question number jo fourth hai wo hai Magnification of compound microscope is not connected with. Compound microscope ka jo magnification hota hai wo kiske saath connect nahi hota hai? Numerical aperture, focal length of objective, focal length of eyepiece ya fir tube length. Toh wo numerical aperture ke saath. Ab ye dekhiye kaafi purane question hai bahut hi old hai. Ab aap recent ke andar question dekhoge toh aise question nahi aate hain. Pure NCERT based aate hain but ye Physics jaisa portion tha. Chaliye ab jo hamara important topic start hota hai aur yahan se question aate bhi hain sabse pehla hi question pucha gaya Cell Theory se related. Cell theory me question number fifth aapka pucha gaya tha the concept of "Omnis cellula-e-cellula" regarding cell division was first proposed by. Yaani jo Omnis cellula-e-cellula ka jo concept hai wo sabse pehle cell theory me kisne diya tha? Aristotle ne, Rudolf Virchow ne, Theodore Schwann ne, Schleiden ne. Toh yahan pe Rudolf Virchow ne hi ye cheez bola tha Omnis cellula-e-cellula, yaani jo new cells hai wo purane existing cells se hi bante hain. Question number sixth hai Which is correct about cell theory in view of current status of our knowledge about cell structure? Toh yahan pe bilkul correct statement hume batani hai cell theory ke portion ke hisaab se aur bilkul current status ke hisaab se. It needs modification due to the discovery of subcellular structures like chloroplasts and mitochondria. Modified cell theory means that all living beings are composed of cells capable of reproducing. Cell theory does not hold good because all living beings (e.g. viruses) do not have cellular organisation. Toh yahan par correct statement batani hai hume about the cell theory. Toh cell theory jo hai wo har ek object ke liye bilkul good nahi baithti hai kyunki jaise living organisms jaise aapke virus wagera jo host ke andar jab chale jaate hain wo living condition me aa jaate hain. But unke paas koi bhi celluler component nahi hai. Toh cell theory does not hold good because all the living beings example virus do not have the cellular organization. Next hamara question number seventh hai Names the Schleiden and Schwann are associated with. Toh Schleiden and Schwann jo the wo kiske saath associated the? Protoplasm as the physical basis of life, cell theory, theory of cell lineage ya fir nucleus functions as control center of the cell. Toh cell theory ke andar hi naam aata hai aapka Schleiden and Schwann ka. Okay next ab hamara jo next topic hai wo hai An Overview of Cell. Ab yahan se bhi aise question aaye hue hain jo aapke physics wagera me kaam aate hain. Angstrom is equal to 1 Angstrom kiske equal hota hai? 1 Angstrom hota hai aapka 10 ki power -10 meter ke equal. 10 ki power -10 meter ke equal hota hai 1 Angstrom. Toh aap usko millimeter ke andar convert karoge toh aapka nikal kar aayega 0.0001 millimeter toh aapka answer aa jayega option (c).
[6:26]Okay next hamara question number ninth hai Organelles can be separated from cell homogenate through. Jo organelles hai unko hum kaise separate kar sakte hain homogenate through se?

Sodium and potassium ion move across cell membrane by passive transport. Proteins make up 60 to 70% of the cell membrane. Lipids are arranged in a bilayer with polar heads towards the inner part. Fluid mosaic model of cell membrane was proposed by Singer and Nicholson. Sodium aur potassium active transport hai. Protein jo 52% hote hain. Lipids are arranged in a bilayer. Polar head outer hote hain not inner hote hain. Fluid mosaic model Singer and Nicholson ne diya tha 1972 me. Toh hamara answer aa jayega option (d). Next hamara question number jo hai wo 56 hai. What is true about ribosomes? Ribosome ke according true batana hai konsi bilkul true hai. The prokaryotic ribosomes are 80S where S stands for sedimentation coefficient. These are composed of ribonucleic acid and proteins. These are found only in eukaryotic cells. These are self-splicing introns of some RNAs. Toh yahan pe ye jo hai wo RNA aur protein se milkar bante hain toh these are composed of ribonucleic acid and protein. Ye bilkul true likha hua hai. Next hamara question number 57 me bola gaya hai which one of the following does not differ in E.coli and Chlamydomonas? E.coli jo hai wo aapka prokaryotic ke andar aa jata hai. Chlamydomonas jo hai wo unicellular aapki algae hai toh wo aapka eukaryotic ke andar aa jata hai. Toh prokaryotic aur eukaryotic me kya cheez alag nahi hai? Ribosome, chromosomal organization, cell wall ya fir cell membrane. Toh cell membrane sab me ek jaisi hoti hai chahe wo prokaryotic ho, eukaryotic ho toh yahan pe answer aa jayega option (d). Question number 58 me bola gaya hai which one of the following cellular parts is correctly described? Toh yahan pe bilkul jo correctly described kiya gaya hai. Thylakoid me bola gaya hai flattened membranous sacs hote hain forming the grana of chloroplast. Centriole me bola gaya hai site of active RNA synthesis. Ribosome me bola gaya hai those on chloroplast are larger (80S) while those in the cytoplasm are smaller (70S). Aur yahan pe (d) me bola gaya hai optimally active at a pH of about 8.5. Toh yahan pe correct batana hai. Toh thylakoid jo hote hain wo flattened membranous sacs hote hain jo kya banate hain grana banate hain chloroplast ke andar. Ye bilkul correct hai baki sabhi incorrect hain. Question number 59 me pucha gaya hai which one of the following structures is an organelle within an organelle? Organelle within organelle? Ribosome, peroxisome, endoplasmic reticulum ya fir mesosome. Endoplasmic reticulum ek aapka organelle hai jo ki agar organelle ke andar bhi rehta hai jaise wo nucleus me bhi milega, hume mitochondria me milega, chloroplast me bhi milega. Toh ribosome jo cell within an organelle hai. Toh answer aa jayega option (a). Next hamara question number 60 me pucha gaya hai peptide synthesis inside a cell takes place in. Peptide synthesis cell ke andar kahan pe ho gaya? Chloroplast me, mitochondria me, chromoplast me, ribosome me. Toh ribosome jahan pe bhi hoga wahan pe protein synthesis hoga toh answer aa jayega option (d). Next hamara question number 61 me pucha gaya hai important site for formation of glycoproteins and glycolipids is. Glycoprotein aur glycolipid ke liye important site konsi hai? Vacuole hai, golgi apparatus hai, plastid hai, lysosome hai. Toh golgi apparatus hai toh answer aa jayega option (b).
