- •
We examined the relationship between CO2, photo-physiology and intracellular pH.
- •
CO2-addition enhanced photo-physiological performance and Symbiodinium density.
- •
Photosynthesis increased at a greater rate than respiration preventing cellular acidosis.
- •
Strong causal relationship between symbiont pHi and host cell pHi
