Effect of different colors of light on the rate of photosynthesis.

In this experiment you need three experimental groups, each for every irrigation method (flood, spray or drip) and in this case you don't need a control group at all. In this experiment the irrigation method is the independent variable and the resulting growth rate of the radishes is the dependent variable. Treat each group of plants the same (light, water quantity, nutrition, cultivation, etc.) besides your independent variable - the different irrigation method.In an comparative experiment you can test, of course, the effect of a few independent variables but not in the same experimental group where also only one independent variable is allowed as in the case of a controlled experiment.

Effects of different colors of light on the photosynthesis rate.

Prediction:I predict that raising the light intensity will increase the rate of photosynthesis.

Investigating the effect of light intensity on the rate of ..

Results of these experiments suggest that violet, blue, and red light with peaks away from the absorption maxima of carotenoids present in zooxanthellae are most efficient in the promotion of photosynthesis. See Table 9.

effect of light intensity on the rate of photosynthesis

Saturation, Photosynthetic: Photosynthetic Saturation is reached when an increased amount of light does not increase the rate of photosynthesis. Sub-saturating light intensity is that seen between zero photosynthesis and just below saturating intensity.

Graph: Shows the effect of light intensity on the process of photosynthesis in an aquatic plant.

Light intensity is a factor in the rate ..

Effect of different colors of light on the rate of photosynthesisThe effect of different lights on plant growth: incandescent light, fluorescent light, sunlight and black light.

Results obtained from experiment : "Investigating if light intensity
effects the rate of photosynthesis in an aquatic plant."

As mentioned previously, the results I have obtained from the
experiment will be of measured in 5 intervals, ranging from 0cm
-100cm, 1 repeat reading taken as well as an original reading & an
average of the 2 results calculated.

coli Promotion of Photosynthesis in ChloroplastThe effects of the intensity of light on the rate of photosynthesis in plants.

Effect of Light Intensity on Photosynthesis: Lab Experiment



The most probable explanation for the results I gained; as mentioned
previously in my introduction, as light is one of the factors required
in order for photosynthesis to take place, as the intensity of the
light is increased, photosynthesis is able to take place at a higher
rate.

I am happy with the experiment as I proved that light intensity has an effect on the rate of photosynthesis.

Light intensity rate of photosynthesis experiment ..

Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.

Graph Y shows a steeper rate of increase, and levels of at 30 degrees Celcius.

a certain level of light intensity

I can say that the
increase in distance thus making the light intensity stronger
increased the rate of photosynthesis and when further away made the
rate of photosynthesis almost come to its limiting factor the
straitening of the graph.
