What is the relationship between the increase in light intensity and the photosynthetic rate in leaves from a corn plant? How does this relationship compare with what you observed for tomato plants? As light intensity increases, the photosynthetic rate of a plant increases as well. However biochemical reaction, in fact, DO have temperature limits because if the temperatures reach a certain degree and overheat, the enzymes will get damaged and/or lost and inevitably die. Therefore, temperatures must be a tolerable limits in order to increase a photosynthetic rate. Photosynthesis at low temperatures actually take CO2

The purpose of this LeafLab report was to help better my understanding the process of photosynthesis. It helped me comprehend the rate of photosynthesis in several different plants and how it can change from factors that happen naturally on earth. The factors that affect and change the rate of photosynthesis include light intensity, light quality, CO2, concentration, and of course temperature. I was able to examine, differentiate, and compare photosynthesis in different types of plants; such as C3 and C4 plants. I was able to simulate and take measurements of the rate of carbon dioxide in the leaves of plants, and investigate light and dark respiration, the efficiency of
