Question

2. During photosynthesis, plants take in CO2 and give
out O2, while during respiration the plants take in
O2 and give out CO2. Photosynthesis usually occurs
during daytime while respiration occurs continuously
for 24 hours. Then, how does the balance of O2 and
CO2 remain almost constant?​

Answer 1

Answer:

because they take CO2 and give O2 during day time and they resperate means take O2 and exhale CO2 during night time
