Curiosity (Reprint 2026-27) ke Chapter 2, Diversity in the Living World, ki Activities 2.1 se 2.10, in-text sawaalon aur “Let us enhance our learning” ke saare 10 sawaalon ke jawab. Page numbers book se milte hain. Kai kaam tumhaare apne observations hain, isliye jawab sample entries dikhaate hain; tumhaari list alag hogi. Short notes: Chapter 2 notes.

Activity 2.1: aas-paas ke paudhe aur jaanwar (pages 10–12)

Table 2.1, sample entries ke saath (pehli do rows aur baaki ka kuch hissa book mein diya hai):

Paudha	Tana	Pattiyan	Phool	Aur visheshtaayein
Aam ghaas	Naram aur patla	Tane par alag-alag jagah se ek-ek patti baari-baari se	Aasaani se nahi dikhte	Hari pattiyan
Tulsi	Sakht aur patla	Pattiyon ka joda aamne-saamne	Gulaabi-bainganee	Masalne par tez khushboo
Gudhal	Sakht	Chaudi, daantedaar kinaaron waali pattiyan, har jagah ek	Bade, aksar laal, paanch pankhudiyan	Taproot hota hai
Neem	Sakht aur mota	Chikni satah waali pattiyan	Chhote aur safed	Chhaaya dene waala lamba ped

Paudhon mein samaanta aur antar: sabke tane, pattiyan aur jadein hain, aur zyaadatar mein phool hain. Ve lambaai mein, tane ke sakht ya naram, mote ya patle hone mein, pattiyon ke aakaar aur bichhaav mein, aur phoolon ke rang, aakaar aur khushboo mein alag hain.

Table 2.2, sample entries ke saath:

Jaanwar	Kahan rehta hai	Khaana	Kaise chalta hai	Aur visheshtaayein
Kauwa	Ped	Keede	Udta aur chalta hai	Chonch mein tinka le jaata hai
Cheenti	Mitti mein ghonsla, bil	Pattiyan, beej, keede	Chalti hai	Chhe pair
Gaay	Gaushaala aur khet	Ghaas, pattiyan	Chalti hai	Chaar pair aur do seeng
Mendhak	Taalaab aur aas-paas ki zameen	Keede	Phudakta aur tairta hai	Geeli twacha, lambe pichhle pair
Machhli	Taalaab ya nadi	Paani ke chhote paudhe aur jeev	Tairti hai	Fins aur poonchh

Jaanwaron mein samaanta aur antar: kuch zameen par, kuch pedon par, kuch paani mein, aur kuch, jaise mendhak, zameen aur paani dono par rehte hain. Ve alag khaana khaate hain aur alag tarah chalte hain: chalna, udna, phudakna ya tairna.

Activity 2.2: let us appreciate (page 13)

Jawab alag honge. Class aam taur par kai alag paudhe (aam, gulaab, tulsi, bargad) aur jaanwar (kutta, billi, gaay, mor, titli) banaati hai. Phir bhi paudhon aur jaanwaron ke itne prakaar hain jitne poori class bhi nahi bana sakti: kisi ilaake ki ye vividhta uski biodiversity hai.

Jeevon ki ek-doosre pe nirbharta ke aur udaharan (page 14)

• Pakshi pedon par ghonsle banaate hain aur pattiyan khaane waale keede khaate hain.
• Madhumakkhiyan aur titliyan phoolon ka ras peeti hain aur ek phool se doosre tak paraag (pollen) le jaati hain, jisse paudhon mein phal aur beej bante hain.
• Gaay aur bakri ghaas khaati hain, aur unka gobar mitti ko upjaau banaata hai.
• Kenchue mitti ko dheela karte hain, jisse jadein badhti hain aur paani-hawa le paati hain.

Grouping aur Activity 2.3 (pages 14–15)

Apni kitaabein aur copiyan kaise rakhoge? Subject ke hisaab se (Science ki saari kitaabein saath), prakaar se (textbooks aur copiyan alag) ya size se. Haan, grouping madad karti hai: zaroorat ki cheez jaldi milti hai aur bag saja rehta hai.

Alag groups alag aadhaar kyun lete hain? Har group alag common visheshta chunta hai. Koi paudhon ko lambaai se, koi phool hone ya na hone se, ya sakht-naram tane se group karta hai; jaanwaron ko khaane, rehne ki jagah, rang ya chaal se. Har aadhaar sahi hai agar use theek se lagaaya jaaye.

Activity 2.4: herbs, shrubs aur trees (pages 15–17)

Table 2.3, teen aur paudhon ke saath:

Paudha	Lambaai	Tana	Shaakhaayein	Group
Aam	Lamba	Bhoora, sakht, mota	Tane par upar se	Tree
Gulaab	Madhyam	Bhoora, sakht, patla	Zameen ke paas se	Shrub
Tamatar	Chhota	Hara, naram, patla	Zameen ke paas se	Herb
Neem	Lamba	Bhoora, sakht, mota	Tane par upar se	Tree
Gudhal	Madhyam	Bhoora, sakht, patla	Zameen ke paas se	Shrub
Pudina	Chhota	Hara, naram, patla	Zameen ke paas se	Herb

Herbs, shrubs aur trees mein fark: trees lambe hote hain, sakht, mote, bhoore, lakdi jaise tane, shaakhaayein upar se; shrubs madhyam lambaai ke, kai sakht lakdi jaise tane zameen ke paas se shaakhaon mein bantne waale; herbs chhote, naram hare tane waale. Yaani lambaai, tane ka prakaar aur shaakhaon ki shuruaat group tay karti hai.

Activity 2.5: venation (page 17)

Fig. 2.4a aur Fig. 2.4b ki naso mein fark: gudhal ki patti mein beech ki moti nas ke dono taraf chhoti naso ka jaal hai (reticulate venation); kele ki patti mein nasein ek-doosre ke saath-saath chalti hain (parallel venation).

Kya paudhon ko venation se group kar sakte hain? Haan: reticulate venation waale aur parallel venation waale paudhe.

Activity 2.6: jadein (page 18)

Jadon mein samaanta aur antar: saari jadein paudhe ko mitti mein thaame rakhti hain, par kuch paudhon mein ek moti mukhya jad aur patli side roots hoti hain, jabki kuch mein ek jaisi patli jadon ka guchha.

Fig. 2.5a aur Fig. 2.5b: sarson mein taproot hai, ek mukhya jad aur side roots; ghaas mein fibrous roots hain, tane ke aadhaar se nikalti ek jaisi patli jadein.

Tumhaare collection mein aur ghaasein? Doob ghaas jaisi ghaason mein bhi fibrous roots hoti hain.

Activity 2.7: venation aur jadein (page 19)

Table 2.4, sample entries ke saath:

Paudha	Patti ki venation	Jadein
Lemongrass	Parallel	Fibrous
Genda	Reticulate	Taproot
Sadabahar	Reticulate	Taproot
Makka	Parallel	Fibrous
Tulsi	Reticulate	Taproot

Kya koi rishta hai? Haan. Aam taur par reticulate venation waale paudhon mein taproot aur parallel venation waalon mein fibrous roots hoti hain. Chana (reticulate, taproot) aur gehun (parallel, fibrous) bhi isi niyam par chalte hain.

Activity 2.8: beej (page 20)

Kya chane aur makka ke beej ek jaise hain? Nahi. Bhigoya hua chana do hisson, do cotyledons, mein khulta hai; makka mein ek patla cotyledon hota hai.

Venation, jadon aur cotyledons ka rishta: dicots (do cotyledons, jaise chana) mein reticulate venation aur taproot; monocots (ek cotyledon, jaise makka) mein parallel venation aur fibrous roots.

Activity 2.9: jaanwaron ki chaal (pages 21–22)

Table 2.5, kuch aur jaanwaron ke saath:

Jaanwar	Chaal ka prakaar	Kaunse ang
Cheenti	Chalti hai	Pair
Bakri	Chalti aur koodti hai	Pair
Kabootar	Chalta aur udta hai	Pair aur pankh
Makkhi	Chalti aur udti hai	Pair aur pankh
Machhli	Tairti hai	Fins (aur poonchh)
Mendhak	Phudakta aur tairta hai	Pair
Saanp	Rengta hai	Poora shareer
Batakh	Chalti, tairti aur udti hai	Pair, jaaldaar panje aur pankh

Nishkarsh: alag jaanwar alag tarah chalte hain (udte, daudte, rengte, chalte, phudakte ya koodte, aur tairte hain) aur alag ang use karte hain: pair, pankh, fins ya poora shareer. Jaanwaron ko chaal se group kar sakte hain, jaise udne waale, tairne waale aur chalne ya rengne waale.

Activity 2.10: alag maahaul ke jeev (pages 23–24)

Kya chaal maahaul pe nirbhar hai? Haan. Machhli paani mein rehti hai aur fins aur streamlined shareer se tairti hai; bakri ghaas waali jagah mein rehti hai aur pairon se chalti hai.

Table 2.6, sample entries ke saath:

Registaan mein	Pahaadon par	Samudra mein	Jungle mein
Oont	Deodar ka ped	Machhli	Sher
Cactus	Yak	Whale	Baagh
Khejri ka ped	Rhododendron	Octopus	Haathi

Observations: ek tarah ke ilaake ke paudhe aur jaanwar doosre ilaake se alag hote hain. Sthitiyan alag hone se biodiversity ilaake-ilaake mein badalti hai, aur jeevon mein apne ilaake ke laayak visheshtaayein hoti hain.

Oont aur doosre adaptations (pages 25–26)

Dono oonton mein fark aur unke fayde: garam registaan ke oont ke lambe pair aur chaude khur use ret mein dhansne se bachaate hain, aur ek kubad khaana jama karta hai. Thande registaan ka oont chhota hai, chhote pair pahaadi ilaake mein chalne ke liye, do kubad late winter ke liye khaana jama karte hain, aur sir se gardan tak lambe baal garmi dete hain.

Registaan mein jeene mein madad karne waali aur visheshtaayein: oont kam peshaab karte hain, unka gobar sookha hota hai aur unhe paseena nahi aata, isliye ve kam paani khote hain aur kai din bina piye reh sakte hain. (Extra: unki lambi palkein aankhon mein ret jaane se rokti hain.)

Habitats (pages 27–29)

Agar habitat bigad jaaye to kya hoga? Paudhe aur jaanwar apna ghar, khaana aur doosre saadhan kho dete hain; kai mar jaate hain ya door chale jaate hain, aur biodiversity ghat jaati hai. Bina ghaas ke bakri bhookhi rahegi, aur machhli bina paani ke zinda nahi reh sakti.

Bujurgon ne bachpan mein jo paudhe aur jaanwar zyaada dekhe: jawab alag honge. Kai parivaar gauraiya (house sparrow), giddh, jugnu ya kuch ped aur jangli phool bataate hain jo ab kam dikhte hain.

Tumhaare ilaake ke sacred groves: jawab tumhaari jagah pe nirbhar hai. (Extra: sacred groves ke sthaaniya naam hain, jaise Maharashtra mein devrai, Kerala mein kavu, Rajasthan mein orans aur Jharkhand mein sarna.)

Let us enhance our learning (pages 31–33)

1. Gehun aur rajma: jadon aur venation mein fark

Gehun monocot hai: iske paudhon mein fibrous roots aur pattiyon mein parallel venation hoti hai. Rajma (kidney bean) dicot hai: iske paudhon mein taproot aur pattiyon mein reticulate venation hoti hai.

2. Jaanwaron ko habitat ke hisaab se group karo

• A, aquatic: dolphin, whale.
• B, terrestrial: ghoda, bhed, gilahri, kenchua, kabootar, kachhua (tortoise).
• C, dono: mendhak, magarmachh.

Tortoise zameen par rehta hai; uske rishtedaar turtles apni zindagi ka bada hissa paani mein bitaate hain.

3. Mooli: jad ka prakaar aur venation

Mooli taproot hai: ek moti mukhya jad (jo khaana jama karti hai) aur patli side roots. Isliye iski pattiyon mein reticulate venation hogi.

4. Pahaadi bakri aur maidaan ki bakri

Samaanta: dono ke chaar pair aur khur hain, seeng hain, shareer baalon se dhaka hai, aur dono paudhe khaati hain.

Antar: pahaadi bakri ke bahut ghane, lambe, jhabre safed baal aur pathreeli dhalaanon ke liye mazboot pair aur khur hain; maidaan ki bakri ke chhote, patle baal hain.

Kaaran: dono apne habitat ke anusaar adapted hain. Ghane baal pahaadi bakri ko thande, barfeele pahaadon mein garam rakhte hain, aur mazboot pair chadhne mein madad karte hain; maidaan garam hain, isliye patle baal kaafi hain.

5. Jaanwaron ko kisi aur visheshta se group karo

Reedh ki haddi (backbone) se, jo chapter mein nahi hai:

• Reedh ki haddi waale: gaay, kabootar, chamgaadad, kachhua, whale, machhli, chhipkali.
• Bina reedh ki haddi ke: cockroach, tidda (grasshopper).

Doosra tareeka hai bachche kaise paida hote hain: bachche ko janm dene waale (gaay, chamgaadad, whale) aur ande dene waale (cockroach, kabootar, kachhua, machhli, tidda, chhipkali).

6. Katte jungle

Asar: jaanwar aur paudhe apna habitat kho dete hain, isliye biodiversity ghatti hai; jangli jaanwar shehron aur kheton mein aa sakte hain; baarish mein mitti aasaani se beh jaati hai aur baadh badh sakti hai; jagahein garam aur hawa dhool bhari ho jaati hai; aur jungle pe nirbhar log khaana, eendhan aur dawaayein kho dete hain.

Hum kya kar sakte hain: ped lagaayein aur unki dekhbhaal karein, protected areas aur sacred groves jaise samudaay ke prayaason se jungle bachaayein, kaagaz aur lakdi soch-samajh kar use karein aur recycle karein, sadak aur imaaratein aisi jagah banaayein jahan jungle na kaatne padein, aur jaagrukta failaayein, jaise Save Silent Valley andolan ne kiya.

7. Flowchart: A aur B ke udaharan

A (pattiyan hain, reticulate venation ke saath): gudhal, aam, gulaab, sarson, chana ya neem.

B (pattiyan hain, par reticulate venation nahi, yaani parallel venation): ghaas, gehun, makka, kela ya lemongrass.

8. Kya gudhal shrub hai? Sanjay ke sawaal

• Paudha kitna lamba hai: tumse chhota, tumhaare jitna, ya ped jitna?
• Tana hara aur naram hai, ya bhoora, sakht aur lakdi jaisa?
• Tana ped ke tane jaisa mota hai, ya kai patle tane hain?
• Shaakhaayein zameen ke paas se shuru hoti hain ya tane par upar se?

Agar paudha madhyam lambaai ka hai aur uske kai sakht, bhoore, lakdi jaise tane zameen ke paas se shaakhaon mein bantte hain, to Raj sahi hai: wo shrub hai.

9. Group A aur B ke udaharan

Group	Beej	Jad	Udaharan
A	Dicot	Taproot	chana, sarson, rajma, gudhal, aam, sadabahar
B	Monocot	Fibrous roots	gehun, makka, chaawal, ghaas, lemongrass, kela

(a) Group A ke paudhon ki pattiyon mein reticulate venation bhi hoti hai.

(b) Group B ke paudhon ki pattiyon mein parallel venation bhi hoti hai.

10. Batakh ke pair

Batakh ki ungliyan ek patli twacha se judi hoti hain: uske jaaldaar pair (webbed feet) hain. Doosre pakshiyon, jaise kabootar, ki ungliyan alag hoti hain aur unme chalne aur daal pakadne ke liye panje hote hain. Jaaldaar pair chappu ki tarah kaam karte hain, isliye batakh paani mein tair sakti hai.

Learning further (pages 33–34)

Kisi scientist ya wildlife biologist par chhoti report: likho ki ve kaun hain, kahan kaam karte hain, kaunse paudhe, jaanwar ya jagahein padhte ya bachaate hain, unhone kya khoja ya haasil kiya, aur India ki biodiversity ke liye ye kyun zaroori hai.

Extra: book ke saat naamon ke liye shuruaati jaankaari (details kitaabon ya bharosemand websites se check karo):

Naam	Kis kaam ke liye jaane jaate hain
Divya Mudappa	Western Ghats ki Anamalai Hills mein rainforest waapas ugaana
Usha Lachungpa	Sikkim ke wildlife ka adhyayan aur bachaav
Ghazala Shahabuddin	Pakshiyon aur jungle ka adhyayan, aur log aur wildlife zameen kaise baant sakte hain
