Question

I have a question that if carbon dioxide is harmful to us is oxygen also harmful to plants .Why

Answer 1

Heya,

U have asked a good question..let me help u out..

See the plants take CO2 and removes O2 while photosynthesis, but as we know that photosynthesis is a process that occures only in day time..in night the plants don't do photosynthesis..
And as the plant is also an organism so it also do respiration that means that it takes O2 and release CO2 but during the day time as it does more photosynthesis so the amount of CO2 doesn't increases..

If plant do respiration that doesn't mean that plant do not need O2 and this also doesn't mean that O2 is harmful to plants.
Like all other organisms they also do respiration so they need O2 for there respiration also...

Hope this helps....:)

If not understood u can re-ask..
