What is the ratio for O2 to CO2

O2• The rates of CO2 uptake and O2 evolution exhibit nearly identical responses to CO2 pressure within each species while the absolute rate of CO2 uptake appears to be slightly higher than the rate of O2 evolution at all CO2 pressures, giving a C02/02 exchange ratio of 1.04 to 1.14.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
