How fast do sunflowers breathe?

Sunflowers, like other plants, do not "breathe" in the same way animals do. Instead, they exchange gases through tiny openings called stomata, which regulate the intake of carbon dioxide and the release of oxygen during photosynthesis. This process occurs at varying rates depending on factors like light, temperature, and humidity. Generally, stomatal opening and gas exchange are most active during the day when sunlight is available.
