okay, this might be a little confusing because I don't really know how to explain it, but please give it a go?
"The drawing shows a 'bottle garden' which is kept in a brightly lit room. The cork in the neck of the bottle is not taken out.
(Picture of the bottle garden)
The plants in the bottle use oxygen for respiration.
Explain why, over a week, the amounts of oxygen and carbon dioxide in the bottle stay about the same."
I'm really confused :( help me out?
Hmm, it's something to do with photosynthesis and respiration... the plant would create oxygen through photosynthesis but then would use up that oxygen during respiration.
photosynthesis - 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2
respiration - C6H12O6+6O2 = 6CO2+6H2O+36ATP
see they are basically opposite reactions...
I always thought they didnt use up the same amount as they created. I'll do a little more research on it.
ok, so according to wikipedia, there is a net output of oxygen, so I'm not sure why it would be the same amounts... sorry...
because there is no oxygen/carbon dioxide getting in or out of the bottle?
dunno if thats wright thoo
Good Luck
