When light intensity increases then the tempo of photosynthesis increases, until however it reaches a level where the rate levels off. This is called the light saturation point of photosynthesis. This is because as light intensity increases, the photosynthetic rate of a plant increases as well. However biochemical reaction, have heat limits because if the temperatures reach a certain degree and overheats, the enzymes will become damaged, and the leaf will burn. Therefore, temperatures must be bearable in order to increase a photosynthetic rate. Photosynthesis at low temperatures takes CO2 more effectively. However photosynthesis in corn is diverse from photosynthesis in a tomato. Corn is part of CO4. Plants with CO4 are able to capture CO2 into precursor acids. Therefore CO2 is kept at a constant rate. Increases and decreases in temperature do not affect the rate of CO2. Corn is able to maintain resourceful energy production which seems allows it to keep growing. From what I have experience of the tomato leaf it is incapable of converting carbon dioxide and water into oxygen and organic matter as resourceful. Tomato plants are highly affected on increasing temperatures on the rate of photosynthesis. The photosynthetic saturation point, maximum photosynthetic rate, and yield the decreased at all the increase stages, but the decrements differed with growth stages and were not consistent with the low light tolerability of the test. With the corn leaf photosynthesis must be determined first by plotting O2 evolution when dealing with time at different light levels. The rates calculated from O2 evolution curve are then plotted against the level of light. When photosynthesis rates from several experiments are plotted against light intensity, the result is a photosynthesis light response curve.
