Factors limiting photosynthesis. Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. The presenters use graphs to explain how light, carbon dioxide and temperature affect the rate of photosynthesis. The difference between the graphs for temperature. Simple visual stimulus of limiting factor graph shapes. Also could lead into a practical on measuring oxygen bubbles of Elodea. Teachers can add their own. A tutorial explaining how each of the three major factors which limit the rate of photosynthesis. Includes references to the Light Dependent Reaction and. 1. J Gen Physiol. 1938 Sep 20;22(1):21-35. LIMITING FACTORS IN PHOTOSYNTHESIS: LIGHT AND CARBON DIOXIDE. Smith EL(1). Author information: (1)Laboratory. 1 Rate of photosynthesis: limiting factors Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration Limiting factor is something present in the environment in such short supply that it restricts life processes. Three factors can limit the speed of photosynthesis -. Abstract. Earlier work (SE Taylor, N Terry [1984] Plant Physiol 75: 82-86) has shown that the rate of photosynthesis may be colimited by photosynthetic electron. The maximum rate of photosynthesis is controlled by the limiting factor.For instance, increasing the temperature from 10ºC to 20ºC could double the. A good ppt about limiting factors on photosynthesis.
