Factors affecting the rate of photosynthesis 1

Even though we are measuring whether the
rate of photosynthesis is affected by different levels of exposure to
CO2, It would only be a fair test if the different range of levels can
clearly be measured, which they cannot be clearly measured if the test
is conducted with the same water, even though the levels of CO2 would
be different.

By adjusting the
levels of carbon dioxide available to the plant I could still measure
whether this affects the rate of photosynthesis in pondweed.

Our experiment tested which color (red, blue, green) would influence the plant to produce the most amount of photosynthesis. There are four main photosynthetic pigments found in the chloroplast of the plant called chlorophyll a, chlorophyll b, xanthophylls, and carotenes. All these pigments absorb light and possibly utilize the light energy in photosynthesis. Light energy is essential for photosynthesis. An initial experiment showed that all the pigments at peak absorbance showed violet/blue light at the highest level, orange/red light as the second highest, and yellow/green having the lowest level of absorption. We hypothesized that photosynthesis was affected by the light absorption rate.

How Light Intensity Affect Photosynthesis Essay …

Plants utilize the process of photosynthesis to convert solar energy into chemical energy to produce cellular respiration. The process of photosynthesis uses the energy of sunlight, which is then absorbed into different pigment types to help the cyclical functions that eventually create atmospheric oxygen. In this experiment we asked how different colors of light effect the rate of photosynthesis. The experiment attempted to see how blue colored and red colored lights affected the rate of photosynthesis. It was hypothesized that because plants absorb more red light, then we predict plants in red light should have a higher rate of photosynthesis when compared to plants in blue. The hypothesis was tested by taking the leaves of a live plant and placing the leaves in a flask. A carbon dioxide gas probe was then placed in the flask to test if the levels of carbon dioxide changed. The independent variable was the color of light and the dependent variable was the rate of photosynthesis in change in levels of carbon dioxide per minute per gram. The change in carbon dioxide levels were proportional to the rate of photosynthesis. Thus red light and blue light was placed upon the flasks of leaves for a total of thirty minutes. The first and last ten minutes the leaves were set in the light and the second ten- minute increment the leaves were in the dark. The second ten minutes was to see if carbon dioxide levels decreased thus to control the cellular respiration. The results show in comparing the carbon dioxide levels that the p=value is .36 meaning there was no significance in the comparison. Therefore the different wavelengths in light made no extreme difference on the rate of photosynthesis. In comparison to other experiments done by others the results were much the same finding that neither light wavelength affected the rate of photosynthesis. The experiment was done with a limited amount of time and the leaves were most likely dead by the end of the experiment. A better hypothesis would be to see how the wavelengths of different colored lights like yellow and green affect the rate of photosynthesis. The use of more live plants would help obtain better results also.
