Cell: The Unit of Life - Key Exemplar Questions

Is section mein hum kuch important exemplar questions aur unke solutions ko discuss karenge jo 'Cell: The Unit of Life' chapter se related hain.

Question 1: Prokaryotic aur Eukaryotic Cell mein Difference

Yeh ek common question hai. Iska answer dene ke liye aapko in points ko yaad rakhna hoga:

• Nuclear Membrane: Prokaryotic cells mein nuclear membrane absent hoti hai, eukaryotic mein present.
• Cell Organelles: Membrane-bound organelles like mitochondria, Golgi apparatus sirf eukaryotic cells mein hote hain.
• Cell Size: Prokaryotic cells generally smaller (1-10 µm) hoti hain.
• Genetic Material: Prokaryotes mein circular DNA, eukaryotes mein linear DNA chromosomes mein packed hota hai.

Question 2: Cell Organelles ke Functions

Mitochondria, Endoplasmic Reticulum, Golgi apparatus, Lysosomes, Plastids jaise organelles ke functions frequently puchhe jaate hain.

• Mitochondria: Powerhouse of the cell, ATP synthesis ka site.
• Endoplasmic Reticulum (ER): Protein synthesis (RER) aur lipid synthesis (SER) mein involved.
• Golgi Apparatus: Packaging, modification aur transportation of materials.
• Lysosomes: Suicidal bags of the cell, contain digestive enzymes.
• Plastids: Photosynthesis (chloroplast) aur pigment storage ka kaam.

Question 3: Plant Cell vs Animal Cell

Plant cells aur animal cells mein major differences ko tabular form mein represent karna seekhein.

• Cell Wall: Plant cells mein cell wall present hoti hai, animal cells mein absent.
• Plastids: Plant cells mein plastids hote hain, animal cells mein nahi.
• Vacuoles: Plant cells mein large central vacuole, animal cells mein small aur temporary vacuoles.
• Centrioles: Animal cells mein present, plant cells mein generally absent.

Question 4: Fluid Mosaic Model of Plasma Membrane

Plasma membrane ki structure ko Fluid Mosaic Model se explain karna important hai. Yeh model batata hai ki membrane fluid hai aur proteins ismein mosaic ki tarah embedded hain.

• Phospholipid bilayer basic structure hai.
• Proteins integral ya peripheral type ke hote hain.
• Cholesterol fluidity ko maintain karta hai.
• Glycoproteins cell recognition mein help karte hain.

Question 5: Types of Cell Division

Mitosis aur meiosis ke differences, stages aur significance par questions aate hain. Mitosis somatic cells mein hota hai aur meiosis reproductive cells mein.

Mitosis: One division, produces two identical daughter cells, chromosome number same rehta hai (2n to 2n).
Meiosis: Two divisions, produces four non-identical gametes, chromosome number half ho jata hai (2n to n).

Practice Tips for Students

In exemplar questions ko solve karte time diagrams banayein. Cell organelles ke structure ko diagram se samjhein. Important definitions like osmosis, diffusion, active transport ko yaad karein. Previous year CBSE questions aur NCERT textbook ke exercises zaroor solve karein.
