जैव प्रक्रम — EG के अपने शब्दों में सार

Book: Vigyan (BSEB, Class 10 Science)  |  Chapter 5  |  Medium: Hindi (English technical words saath me)

Diagram (caption — labels image par hi lage hain): Hari patti, suraj ki roshni aur pani — prakash-sanshleshan (photosynthesis) ke teen zaroori hisse. Label image par hi diye gaye hain: Suraj, Patti, Pani ki boondein. Is chapter me yahi prakriya sabse pehle samajhni hai, kyunki baaki jeevan-prakriyaein isi se judi hain.

1. Jaiv prakram (Life Processes) kya hain?

Jo kaam har jeevit cheez ko zinda rehne ke liye karne hi padte hain, unhe jaiv prakram kehte hain: poshan (nutrition), shwasan (respiration), parivahan (transport) aur utsarjan (excretion). Inke bina na urja milegi, na shareer ke hisse tak cheezein pahunchegi, na waste bahar niklega. Board me in charon ke naam aur har ek ka ek line ka kaam zaroor poochha jaata hai.

2. Prakash-sanshleshan — paudhe khana kaise banate hain?

Apne shabdon me: hari patti suraj ki roshni ki urja se carbon dioxide aur pani ko milakar glucose (khana) banati hai, aur oxygen chhodti hai. Isme chlorophyll (hari rangat) roshni pakadta hai aur patte ke chhote chhed (stomata) gas ke aane-jaane ka rasta hain. Is prakriya ko samajhne ka sabse aasan tareeka: input = CO₂ + pani + roshni; output = glucose + oxygen. Jo paudhe ye nahi kar sakte (jaise amarbel), wo doosre paudhon se khana lete hain — ise parjivi (parasitic) poshan kehte hain.

3. Manushya me pachan — safar ki kahani

Khana munh se shuru hota hai: daant peesne ka kaam, laar (saliva) starch ko thoda todne ka kaam. Phir aamashay (stomach) me acid aur enzyme khane ko aur chhota karte hain. Asli pachan aur avshoshan chhoti aant (small intestine) me hota hai — wahan pitt (bile) charbi ko chhoti boondon me todta hai aur pancreatic juice baaki kaam karta hai. Bacha hua waste badi aant se bahar nikalta hai. Ek line yaad rakho: munh → aamashay → chhoti aant (pachan + avshoshan) → badi aant (pani ka avshoshan) → bahar.

4. Shwasan aur parivahan — urja aur supply chain

Shwasan: Glucose ko oxygen se todkar urja (ATP) banana. Isme lungs oxygen lete hain aur carbon dioxide chhodte hain; alveoli (chhoti thailiyan) wahi jagah hain jahan gas ka len-den hota hai. Parivahan: Khoon (blood) ek supply chain hai — dil (heart) pump hai, dhamniyan (arteries) khoon ko angon tak le jaati hain, shiraen (veins) wapas laati hain. Paudhon me xylem pani ko jad se patte tak le jaata hai aur phloem khana ko patte se baaki hisse tak pahunchata hai. Xylem = oopar, phloem = khana — ye jodi ulta mat karo.

Caption: गमले में छोटा पौधा — पत्ता ऊपर और जड़ मिट्टी में। सरल चित्र है: इसमें ज़ाइलम-फ्लोएम की नलिकाएँ अलग से नहीं दिखाई गई हैं, वे पाठ में समझें।

5. Utsarjan — waste kaise nikalta hai?

Manushya me gurde (kidneys) khoon ko chhante hain aur waste ko mootra ke roop me bahar nikalte hain. Gurde ki chhoti ikai ko nephron kehte hain. Paudhon me waste patte girne, gond (resin) ya chhaal ke roop me nikalta hai. Ek common galti: shwasan se nikli CO₂ ko utsarjan samajh lena — CO₂ shwasan ka utpaad hai, par mukhya utsarjan ang gurde hain.

Practice set — khud karke dekhein

1. Char jaiv prakramon ke naam aur har ek ka ek line ka kaam likhein.
2. Prakash-sanshleshan ke input aur output apne shabdon me likhein.
3. Khane ka safar munh se lekar avshoshan tak 4 steps me likhein.
4. Xylem aur phloem me farak batayein, har ek kya le jaata hai?
5. Nephron kya hai aur gurde ka mukhya kaam kya hai?

Yaad rakhne ki trick: "Poshan, Shwasan, Parivahan, Utsarjan" — charon ke pehle akshar se ek line banao, phir har ek ke saath ek ang jodo: poshan–aant, shwasan–lungs, parivahan–dil, utsarjan–gurde.

Thoda aur gehrai se — pachan ke teen chhote points

Laar me amylase naam ka enzyme hota hai jo starch ko thoda todta hai — isliye munh me hi pachan shuru ho jaata hai. Aamashay ka acid keetanu maarne ke saath khane ko naram karta hai, aur wahan pepsin protein ko todta hai. Chhoti aant ki andaruni deewar par villi (chhoti ungli jaisi ubhar) hote hain jo avshoshan ka kshetrafal bahut badha dete hain — isliye asli avshoshan yahin hota hai.

Related diagrams — label ke saath

Caption: Paudha, suraj, jad aur mitti — labels image par hi lage hain. Paani ke upar jaane ki disha teeron se is diagram me nahi dikhayi gayi hai; ye diagram sirf hisse pehchanne ke liye hai: jad mitti se paani leti hai, patti suraj ki roshni pakadti hai.

Caption: Do gurde aur unse nikli tube (mutra wahini) — labels image par hi lage hain. Gurde ke andar ki chhoti ikai nephron is diagram me nahi dikhayi gayi hai; use sirf naam aur kaam se yaad rakho: nephron khoon ko chhanta hai.

Important Questions — uttar ya hint ke saath

1. Prakash-sanshleshan ke liye kaun si teen cheezein zaroori hain, aur isse kya banta hai? Uttar: CO₂ + pani + roshni (chlorophyll ki madad se) → glucose + oxygen.
2. Stomata ka kaam kya hai? Uttar: Patte ke chhote chhed jinse gas andar-bahar jaati hai.
3. Laar (saliva) khane par kya karti hai? Uttar: Usme maujood enzyme starch ko thoda tod deta hai.
4. Chhoti aant ko pachan ka mukhya sthan kyun kehte hain? Hint: Socho — pitt aur pancreatic juice kahan milte hain, aur avshoshan kahan hota hai?
5. Xylem aur phloem me do farak likho. Hint: Ek paani le jaata hai, doosra khana — disha aur cheez dono alag hain.
6. Alveoli ki deewar patli kyun hoti hai? Uttar: Taaki oxygen aur CO₂ jaldi paar ho saken.
7. Dil ko pump kyun kehte hain? Uttar: Kyunki wo dhadkan se khoon ko poore shareer me dhakelta hai.
8. Nephron ka kaam kya hai aur waste kis roop me nikalta hai? Uttar: Nephron khoon ko chhanta hai; waste mootra ke roop me nikalta hai.
