Hissa 2: Mukhtasar sawal (3)
Sawal 1. Plant cell aur animal cell mein do farq likhein.
Namoona jawab dekhein
Plant cell mein cell wall aur chloroplast hote hain, animal cell mein nahi. Plant cell mein bari vacuole hoti hai jabke animal cell mein chhoti ya kam.
Sawal 2. Osmosis kya hai?
Namoona jawab dekhein
Paani ke molecules ka kam concentration wale hisse se zyada concentration wale hisse ki taraf semi-permeable membrane se guzarna osmosis hai.
Sawal 3. Ribosomes ka kya kaam hai?
Namoona jawab dekhein
Ribosomes mein proteins banti hain (protein synthesis).
