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.
Carbon dioxide is an essential reactant for photosynthesis to occur. If there is a higher concentration of carbon dioxide, then the rate of photosynthesis will increase, and v â¦ ise versa. If the concentration of carbon dioxide decreases, then the rate at which a plant photosynthesizes will be slower.Resources: I'm an advanced bio student, and we conducted an experiment to test this.f there is a higher concentration of carbon dioxide, then the rate of photosynthesis will increase, and v â¦ ise versa.
