Kya paudhe saans lete hain?
Short mein jawab
Paudhe har samay, har hisse mein respiration karte hain, chaahe wo hara ho ya nahi. Respiration mein glucose oxygen se toot kar energy deta hai, aur carbon dioxide aur paani bante hain: glucose + oxygen → carbon dioxide + paani + energy. Band flask mein rakhe ankurit beej lime water ko doodhiya kar dete hain, yaani wo carbon dioxide chhodte hain.

Paudhe bhi respiration karte hain
Sabhi jeevit cheezein respiration karti hain, aur paudhe bhi. Photosynthesis se khaana banaana energy ko glucose mein jama karta hai; badhne aur naye patte, phool aur beej banaane ke liye paudhe ko wo energy nikaalni padti hai. Ye kaam respiration karta hai, jisme glucose oxygen se toot jaata hai. Photosynthesis ko roshni aur chlorophyll chahiye, par respiration paudhe ke har hisse mein, hara ho ya nahi, din-raat chalta hai.
Carbon dioxide chhodne waale beej
Kuch moong ke beej raat bhar bhigo do aur ek conical flask mein geeli rui pe rakho. Flask ko do ched waali cork se band karo jisme do nali lagi hon. Nali A ko rubber pipe se lime water waali test tube se jodo, aur tulna ke liye lime water ki ek doosri test tube khuli rakho. Set-up ko 24 ghante andhere mein chhod do.
Flask se judi lime water doodhiya ho jaati hai, par khuli tube saaf rehti hai. Lime water carbon dioxide se doodhiya hota hai. Hawa mein carbon dioxide bahut thodi hoti hai, isliye extra carbon dioxide beejon se aayi hogi: ugte samay wo respiration karte hain aur carbon dioxide chhodte hain.
Word equation
Glucose + oxygen → carbon dioxide + paani + energy
Paudhe is energy ko apni badhat aur vikaas mein istemaal karte hain. Patte zaroori oxygen apne stomata se lete hain, wahi chhote ched jinse photosynthesis ke liye carbon dioxide andar aati hai. Jadein mitti ke kanon ke beech ki hawa se oxygen leti hain. (Extra: isiliye paani se bhari, daldali mitti, jiski hawa ki jagah paani bhar jaata hai, kai paudhon ko nuksaan pahunchati hai.)
Badhat ke liye energy
Ugta beej dikhata hai ki respiration kyun zaroori hai. Pehle patte khulne se pehle ankur khaana nahi bana sakta, isliye wo beej mein jama khaane pe jeeta hai. Respiration is jama khaane ko todkar jad aur ankur ko bahar nikaalne ki energy deta hai. Hare patte banne ke baad paudha photosynthesis se apna khaana banaata hai aur use istemaal karne ke liye respiration karta rehta hai. Jama anaaj, phal aur aaloo bhi dheere-dheere apna jama khaana istemaal karte hue respiration karte hain.
Respiration aur photosynthesis
Dono prakriyaayein lagbhag ulti hain. Photosynthesis carbon dioxide aur paani leta hai aur glucose aur oxygen deta hai; respiration glucose aur oxygen leta hai aur carbon dioxide aur paani deta hai. Photosynthesis energy ko khaane mein jama karta hai; respiration use nikaalta hai. Photosynthesis sirf hare hisson mein roshni mein hota hai; respiration har jagah, har samay.
Prakriti mein santulan
Kyunki har prakriya wo istemaal karti hai jo doosri chhodti hai, dono milkar hawa mein oxygen aur carbon dioxide ki maatra ka santulan rakhti hain. Band bottle garden ye chhote paimaane pe dikhata hai: andar ka paudha lambe samay tak badhta reh sakta hai, apne respiration ki carbon dioxide photosynthesis mein aur photosynthesis ki oxygen respiration mein istemaal karke. Indian scientist Kamala Sohonie ko Cambridge se paudhon mein respiration pe research ke liye PhD mili thi.
Ye kyun zaroori hai
Respiration hi wo tareeka hai jisse paudha jama khaane ko jeevan ki energy mein badalta hai.

Respiration ke experiment mein beejon ko bhigo kar geeli rui pe kyun rakhte hain?
Jawab dekho
Jawab: Geeli rui pe bhige beej ugne lagte hain. Ugte beej bahut sakriya hote hain aur tezi se respiration karte hain, isliye itni carbon dioxide chhodte hain ki lime water doodhiya ho jaaye.

Students ke sawal
Kya paudhe respiration karte hain?
Haan. Sabhi jeevit cheezon ki tarah paudhe bhi respiration karte hain. Paudhe ka har hissa, jadein, tana, patte, phool aur beej, glucose ko oxygen se todkar badhat aur vikaas ke liye zaroori energy nikaalta hai.
Respiration photosynthesis se kaise alag hai?
Photosynthesis khaana banaata hai: carbon dioxide aur paani lekar glucose aur oxygen deta hai, sirf hare hisson mein aur sirf roshni mein. Respiration khaana istemaal karta hai: glucose aur oxygen lekar carbon dioxide, paani aur energy deta hai, har hisse mein, din-raat.
Ankurit beejon waala flask andhere mein kyun rakhte hain?
Andhere mein kisi hare ankur mein photosynthesis nahi ho sakta, isliye koi carbon dioxide istemaal nahi hoti. Tab lime water ko doodhiya karne waali saari extra carbon dioxide respiration se hi aati hai.
