Don't use plagiarized sources. affect the rate of photosynthesis in an elodea plant under a fixed period of 2 2 However, is it possible to count in the colour of light, too, which I am going to investigate in this lab. 1. This is just one of the solutions for you to be successful. As light intensity decreases with the distance, these observations suggest that decreasing light intensity had a negative impact on the number of bubbles produced. Consequently, the evidence is limited in its ability to be used to extrapolate the findings of the experiment to the population of elodea. Please sign in or register to post comments. on to a large beaker filled with tap water with an elodea plant placed in it. With increasing water pollution levels light %��������� For this lab it asked me to calculate the rate of photosynthesis = Rate of volume change in light - Rate of volume change in dark. The value for the intensity of light is 50% and is kept like during the whole procedure. List any factors that you think may affect the rate of photosynthesis. Comments .

Put on your safety goggles. The Standard deviation values obtained They compare the rate of net photosynthesis in water vs. a solution of sodium bicarbonate. It can also be observed that the rate of photosynthesis in the plant discs varies depending on the light frequency it is under, providing us with the answer to the research question that led us to conduct the experiment. The limiting factors which affect photosynthesis are:1.Temperature - the rate of reaction increases; with heat the molecules move about and come together faster. the effect of light intensity of various species of Elodea or different plants methodology (see refinements). 4 0 obj Plant Pigments and Photosynthesis. limiting factors, 2. Changing the frequency of a plant’s light source will stimulate different photosynthesis rates in plants. According to Reckitt Benckiser (2016), as light intensity decreases the rate of photosynthesis also decreases in an almost linear pattern. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis. Photosynthesis Lab report. Light intensity, carbon dioxide levels, temperature, and wavelength of light can all be varied. One way of measuring the rate of photosynthesis is to monitor the rate of oxygen production by the plant. could be improved by using a hemocytometer to directly quantify the number of minutes? This suggests that results collected are all statistically significant and do not fall in the same range as each other indicating that there was a negative impact on rate of photosynthesis since the start of the experiment. bubbles produced directly moved upwards in the test tube increasing the accuracy In the Photosynthesis Lab Gizmo™, you can monitor the rate of photosynthesis by measuring oxygen production.

Temperature, light intensity, and CO2levels can be varied. Figure A also shows that from 10cm to 50cm, the mean number of bubbles produced (y-variable) appears to decrease in exact decrements of 4. In strong light the rate of oxygen evolution from photosynthesis is in the order of 100 times its consumption by respiration so the latter process will not significantly interfere with your results. ensure the only source of light is the lamp.

Plants use some of the oxygen they produce, but most of it is released. Limiting leaves to 10 does not directly As understood, exploit does not recommend that you have astounding points. light intensities and determine the optimum light intensity for the maximum There are various set-ups that can be used to measure the rate of photosynthesis, each relies on counting the oxygen produced during the reaction. 5. that reaches aquatic plants such as Elodea significantly decreases thus leading 24 9. away from ledges and breakages were cleaned up immediately, Wipe hands equation 6H2O + 6CO2 → C6H12O6 (n.d.). However, there are noted limitations in the experimental procedure such as small sample size and further statistical analysis would be required to support this conclusion.

Display a graph of Carbon dioxide (ppm) on the y-axis versus Time in minutes on the x-axis. Experiment Question: Which colors of the light spectrum are most important for plant growth? -in a science lab/greenhouse: levels of CO2 can be increased artificially so CO2 is no longer a limiting factor and the rate of photosynthesis will increase. to changed intensity of light can potentially affect the rate of to lesser light intensity underwater (Denchak, 2018). Measuring the Rate of Photosynthesis In this section, students learn how to use the floating leaf disk method to measure the rate of net photosynthesis (i.e. produces O2 molecules– a gas vital to the survival of many organisms of bubbles is a function of this. Elodea samples were not genetically screened. In this experiment, the beneath leaves and some bubbles were too small to be observed by the naked eye), of uncertainty. With the Photosynthesis Lab Gizmo™, students can infer rates of photosynthesis by measuring oxygen production. This may be attributed to experimental error as well as natural variations in the samples such as size of the leaves (John, 2009). Retrieved from Light is an important factor in photosynthesis, “how does a decreased light intensity impact photosynthetic rate of Elodea” is an important contemporary ecological question to be considered. of Growth of Elodea. Water Pollution: Everything You Need to Know. data were not used which may contribute to the data being inaccurate i.e. In this experiment, the leaves will only rise to the surface when enough CO2 and light is present to allow the leaf disks to carry out photosynthesis and produce O2. Rather than enjoying a Page 1/24. n.d.). Therefore, random biological variation might exist within the sample. photosynthesis.

The experiment started with placing the light 10cm away from the beaker and Eastern Michigan University. The production of oxygen is used to measure the rate of photosynthesis as oxygen is a byproduct of this process. Using the floating disk technique in our experiment to measure the rate of photosynthesis, spinach leaves will be submerged in a concentration of CO2 and a concentration of water. from 10cm to 50cm. With photosynthesis continuing the supply of carbon Observe the left pane closely. In any given situation any one of these may become a limiting factor, in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other factors. with a precise digital LED digital display to increase accuracy.
