Which cellular structure in elodea carries out the process that is most to result in increasing pH?

In Elodea, chloroplasts are the cellular structures responsible for photosynthesis, a process that can increase pH. During photosynthesis, chloroplasts convert carbon dioxide and water into glucose and oxygen, consuming CO2, which can raise the pH of the surrounding water. This increase in pH occurs because the removal of CO2 reduces carbonic acid formation, leading to a more alkaline environment.
