Photosynthesis kya hai
Transcript
Photosynthesis: plants apna khana sunlight se kaise banate hain?
Plants ko energy chahiye, aur woh sunlight use karke apna food banate hain.
Photosynthesis mein teen cheezein zaroori hain: sunlight, water, aur carbon dioxide.
Plant ke leaves mein ek green colour hota hai, jishe chlorophyll kehte hain.
Chlorophyll sunlight ko absorb karta hai, bilkul ek solar panel ki tarah.
Roots se water aata hai, aur leaves se carbon dioxide enter karta hai.
Ab photosynthesis ke andar ek chemical reaction hota hai.
6CO_2 + 6H_2O + \text{sunlight} \rightarrow C_6H_{12}O_6 + 6O_2Carbon dioxide aur water milkar glucose bante hain, jo plant ka food hai. Aur oxygen bhi nikalta hai, jo hum breathe karte hain.
- Glucose = plant ka food
Iska matlab photosynthesis se do cheezein milti hain: glucose aur oxygen.
Example: ek mango tree ko sunlight, water aur carbon dioxide se apne mangoes banane ke liye energy milti hai. Agar sunlight na ho, ya pani na ho, toh photosynthesis nahi hota.
- Mango tree photosynthesis
Quiz: photosynthesis mein kaun sa gas plant se nikalta hai? Photosynthesis se plants apna food banate hain aur oxygen dete hain.
- Photosynthesis = life ka foundation
Quick quiz
