Which limitation arises for C3 plants at high temperatures, thus impacting rubisco function within the chloroplast?

💡 Explanation

Photorespiration increases because rubisco fixes O2 rather than CO2 when CO2 levels are low due to heat accelerating water loss and stomatal closure; therefore, photosynthetic efficiency plummets, rather than increasing CO2 intake or a decline in factors like, chlorophyll.
