The study of the “impact of artificial light on the production of sugars and starch by seedlings” was conducted to compare the effectiveness of seed artificial light compared to natural light to see if artificial light could be used as a substitute for artificial light.
To produce the results to create a comparison, students conducted Starch Testing and Carbohydrate testing. The starch testing consisted 6 tubes, two of which were controlled samples with and without a Lugol’s Iodine, two experimental samples with and without Lugol’s, Iodine, as well as one tube with water that contains Lugol’s Iodine. Each tube that contains Lugol’s Iodine had three drops of Lugol’s and ten drops of the other solution. The tubes without Lugol’s only have ten drops of the solution. To continue the Starch Testing, each tube was inserted into the spectrometer and produced Absorbance and Transmittance values for each mixture. The sample with the darkest coloring will have the most starch, thus testing the effect that various starch concentrations have on absorption.
In addition, students conducted Carbohydrate testing to test sugars produced by the seeds. …show more content…
This was shown by the change in color in the Starch Solutions and the change in absorbance levels compared to the controls. Also, the control sample with Lugol’s iodine seemed to have a 35.6% transmittance values compared to the experimental sample of 63.9%, which projects a large difference, therefore the artificial lighting was working but not as well as natural light. As for the Carbohydrate testing, since precipitates were produced and the color had changed, the artificial lighting was not working, the experimental variables did not produce any precipitates, only the control variables did. Therefore, the artificial light is effective but not as well as natural
