Throughout the experiment, the results proved that my hypothesis was correct. “If the plant is grown under green light, then the plant will have the least highest growth in 30 days,” and “If the plant is grown under blue light, then the plant will have the highest growth in 30 days.” Recorded on the table, the green light had the least amount of growth in all three plants (lettuce - 3.3cm, spinach - 2.5cm, radish - 1.3cm), and the blue light had the greatest growth (lettuce - 12.3cm, spinach - 19cm, radish - 14.4cm). On the visible spectrum, wavelengths differ from short with more energy to long with less, but these colours vary when being absorbed into the plant. Red, orange and yellow, have longer wavelengths, meaning they provide the plant with less energy to grow. Green, blue and violet have shorter wavelengths to provide the plant with the maximum energy to help its height growth. Although violet should have the greatest and red have the lowest effect in theory, violet was third best and …show more content…
With various heights among the three different plants, the results came to being blue light has the greatest impact. Blue light has a higher rate for absorption in the pigments. Pigments in the thylakoid membrane (chloroplast), contain two key types, chlorophyll a and chlorophyll b, these types have a slight difference in structure but absorb the blue and red wavelengths. Other accessory pigments absorb these photons between the red and blue spectrum (orange, yellow, green, etc). Another reason for the height is from the wavelength and energy that the blue light produces. The shorter the wavelength, the more energy can be provided, plus the shorter wavelength provides the plant with a better environment to grow. The wavelengths of blue light are shorter because of its placement on the visible spectrum scale, because of its speed, energy is produced and speeds up the grow/height of the
Especially since the experiment states that it was a healthy plant, whereas a yellowish, drooping malnourished plant would not be able to provide sufficient data. So for the time being it'll take in CO2 until it stops functioning without the sun. Tube C would also be yellow because there is no longer equilibrium once the plant runs out of initial energy from it's previous lit environment(before being used for the experiment). Tube D will not change because there is nothing with get the blue
In Burns Bog and Watershed Park, the light was blocked at certain times because of the cover of the trees. Light intensity affects the rate of photosynthesis as with more sunlight, more carbon dioxide can be produced for the plants to grow. The types of vegetation is affected by light intensity as when the amount of sunlight decreases, the growth decreases as well. This is why SWMA has more grass plants such as, Aster and Colonial Bent Grass. According to the Spearman's Rank Correlation Coefficient, the correlation coefficient of light intensity and Aster is 0.4.
The hypothesis that was predicted was that there would be more green plants compared to albino plants. This was hypothesized based on the information given in a punnett square. Punnett squares predict that when two heterozygous green plants are breeded together there is a 3/4 probability their child will be green and 1/4 that that they will be
In the above hypotheses, the research done previous to the lab supported the alternate hypotheses for the colored lights in relation to the dim lights, and the null hypothesis for the experiment in which both sides of the chamber had dim light. The dim light on Side B of the chamber would be favored because, in a previous study, D. Melanogaster were exposed to different illuminations, and “their favorite resting, grooming, and feeding places were determined with an infrared-sensitive camera.” Additionally, the study used infrared beams to collect data on the activity levels of the flies during their most active period of the day under different light intensities. Each of these methods demonstrated D. Melanogaster’s preference for dim light occurring “between 5 and 10 Lux” (Rieger et al.).
The cones that respond to the maximal sensitivity in the long wavelength light respond to orange-red color, cones that respond to the maximal sensitivity in a middle wavelength light respond to yellow-green color and cones that respond to the maximal sensitivity in the short wavelength light respond to blue color. Other colors could be sense through the combination of the three types color. Example, the formation of yellow with the combination of red and green color, formation of magenta with the combination of red and blue color, formation of cyan with the combination of blue and green color and formation of whiteness
Quinn Nguyen Floating Leaf Disk Photosynthesis Lab Conclusion: Graph your results for all 3 trials on one graph. Label the graph, both axes, and provide a legend to distinguish each trial. What was the rate of photosynthesis for each variable? How many leaves floated per minute? Rate of photosynthesis (leaves/min) Spinach: (2-0)/25 = 0.08
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy.
Therefore, Green bacteria overcome low light conditions by absorbing light at longer wavelengths since longer wavelengths can penetrate further into the deep water. What are
Blue is the color of authority. Green is the symbol of ecology and signifies growth, rebirth. Purple symbolizes nobility and luxury to most people in the world. Orange symbolizes energy, excitement, and good health” (Morton). Morton’s point is many colors have numerous definitions and can send different messages by the way people use them.
The objective of this experiment is to determine how light affects photosynthesis. The purpose of this experiment is to determine whether or not colored films have any impact on the rate of transmittance when used with white light. In this experiment, there were three treatments. One was white light that was 60 watt.
There is no doubt that they have a strong impact on psychological and physiological well-being. We cannot assume that the only role of light and color is to provide tolerable lighting and a pleasant environment. Although color vision does not appear in animal life forms, radiative energy and its spectral component still provide various psychological processes in each type of organism. For example: radiant energy is apparently vital to plant growth (Mahanke, F, 1993). Color quantity should
Radiation on different plants could maybe be one of the ways to make plants grow faster. Maybe it could effect a zucchini plant differently than the many other types of plants. Zucchini plants are from the garden family of melons,pumpkins,cucumbers, and gourds.(reader) Electromagnetic radiation could cause a zucchini plant to either sprout faster or slower. This type of radiation comes from a microwave. There are different types of radation such as sunlight,xray,and more.
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
