Is The Whole A Sum of Its Parts?

If one leaf on a plant is pearling and several others are not for whatever reason, is the plant as a whole receiving the Co2 indicated by the pearling or is the one leaf fending for itself and the rest go wanting? By that I mean is the leaf holding on to what it's receiving, or will the pearling leaf actually be passing that elevated level of Co2 throughout the rest of the plant?
Can one leaf indicate what the plant as a whole is receiving?

I guess this is more an aquatic biology or botany question, but I'm curious.

I think the plant as a whole is receiving the Co2 and proccessing it, all the O2 goes out for by the most easy part (most open stomata???) when there are a lot of O2 producing,the O2 presure start to scape in the other leaves. like when you trim the plants a lots of bubbles get out. It only a hipotesis im studying Enginner not biology.

Well, the tops might be actively growing, the lower leaves tend not to have as much light either, CO2 can be higher at the tips where current is higher/light is higher as well, and the tissue is new and more actively growing.

I've measured huge differences in CO2 concentrations in the plant beds(say 10-15ppm), to 40-50ppm in open water that's mixed and coming in from the CO2 diffuser.

Maybe the leaves that aren't pearling are getting more water flow and thus any pearling is being blown away.
