Examination of How Different Colours of Light Affect The Rate of Photosynthesis INTRODUCTION Plants are an essential part of the food chain required by all living things to survive. The growing world population and subsequent alteration to the natural environment has placed increased pressure on available plant resources. This is particularly evident in the area of agriculture‚ where optimum crop productivity is important to meet the increased demand for food by the growing world population

responsible for making the pillbug habitat‚ taking them in and out of the habitat for our experiment‚ setting up the experiment setups for testing‚ and timing the experiment. In my opinion‚ I contributed a lot in my group. I did a majority of the lab proposal‚ and a substantial amount in the lab report. I was always the one getting up to gather our materials and pillbugs from the bins and making sure that our experiment was going as smoothly as intended. From this project‚

Everything except the comb was made of ¼ inch Acrylic Plexiglass. The glass helped the group see what was going on in the experiment. The comb was 3D printed to be more accurate. One material was a casting tray which held the Gel in future steps. The casting

a definite relationship between the light intensity onto the leaf’s surface and the surface area of the leaf. Hypothesis I think the light intensity could affect the surface area in the following way: ·A higher light intensity could make the surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts‚ for photosynthesis. By having leaves of a larger surface

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

How does the Wavelength affect the Refractive Index? The aim of this experiment is to investigate the relationship between the refractive index and the wavelength. We will be testing 5 different wavelengths: 630nm (red)‚ 570nm (yellow)‚ 532nm (green)‚ 445nm (blue) and 405nm (violet). Figure 1 Figure 1 What is the refractive index? The refractive index is the measurement of how hard it is for light to pass through a certain substance‚ thus affecting the speed of light. By knowing the

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

This experiment is so important because vesicle transport in neurons helps to identify many neurological disorders. One such example is a research on Drosophila. Since there is only one kinesin light gene in the subject‚ the mutants in that one chain gene exhibit severe motor neuronal disease (Hirokawa‚ 2008). The disruption of the anterograde and retrograde
