Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Investigation of the effects of environmental factors on the. rate of photosynthesis. The rate of photosynthesis of a photosynthetic plant is. affected by factors such as light quality, light intensity, carbon. dioxide concentration and temperature. A convenient way of investigating the effects of these factors. on the rate of photosynthesis is to measure the volume of. oxygen given off by a plant in a given time.
