We want to test the lower limits of this spectrum, holding our subjects at a range of 2°C, 4°C, and 6°C conditions to see how well the plant survives and grows. Our prediction is that G. turuturu will be viable even at extreme temperatures like 2c, but will not maintain the healthy growth and color of the same plant in warmer water. For this experiment we will need to have been successful in transplanting G. turuturu to a lab setting and will need access to a cooler with day/night light exposure simulation capabilites which can be found at Avery Point facilities.

The 5,000 ppm appeared to have no lateral bud growth and therefore all ranked equally. The last table shows the relationship between the 500 ppm and 5,000 ppm treatments of auxin. It appeared that the bud with the 500 pm showed significantly more lateral bud growth compared to the 5,000 ppm treatment of lanolin The average of the bud growth was recorded in each table and ranks recorded.…
4. Write out the balanced chemical equation for photosynthesis (no peeking!). Sunlight energy + 6H201 + 6C1O2 —> 6O2 + C6H12O6 5. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant?…
It helps increase the range of light a plant can use for energy. ● Carotenoids: This is a class of accessory pigments that occur in all photosynthetic organisms. Carotenoids absorb light maximally between 460 nm and 550 nm and appear shades of red, orange, or yellow. E. What is the meaning of “climax” in…
It also indicated the stem portion of the leaf contained Xanthophyll 1 and Xanthophyll 2. These results can lead to the conclusion that the same pigments, except for chlorophyll, are present in both the green portion of a leaf and a stem. The second test indicated that the green portion of a leaf did not absorb values of 510 nm though 640 nm, which are green wavelengths. Since plants reflect the colors they do not absorb, this data makes sense. It does not have a high absorbance value, meaning that it does not absorb those wavelengths.…
The question of this experiment is, what effect does the darkness have on a plant that requires a lot of light like alyssums? It is hypothesized that the plant will wilt and try to conserve energy in the dark due to its bright natural habitat. The experiment has been designed that the effect of the lighting will be tested…
Throughout the course of the semester we have learned how different variables in an environment can affect the growth, change, and behavior of an organism. Using this research as a guide we set out to design an experiment that would show a particular variable’s effect on brine shrimp eggs. After much debate we decided to use light wavelengths as the variable being tested. We wanted to see the difference in development in the brine shrimp eggs and the development after hatching when exposed to different shades of light versus no light.…
If 5 cuvettes containing spinach/DPIP solution are covered with different cups so that they absorb light of different wavelengths, then the cuvette with no filter will transmit the most orange light because it has been exposed to all white light and has the fastest rate of photosynthesis, followed by cuvettes under red cups, blue cups, green cups, and finally under the opaque cup because it has been exposed to no white light and has the slowest rate of photosynthesis. Fig. 1 and Fig. 2, which are corrected, show that the rate of photosynthesis of a spinach/DPIP solution with translucent red filter was faster than the rate of photosynthesis of a spinach/DPIP solution with no filter. However, Fig. 3 and Fig. 4, which are expressed as means, show how…
9. Once you have observed and recorded your data in a timely manner, increase the intensity of the red LED lights in the room with the red LED lights by 5 nm. Do this at 8:00, so the plants will get the same amount of time exposed to the different levels of light intensity (wavelengths of red LED lights in nanometers). The room with no light stays as it…
Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be controlled.…
Depending upon which color the plant absorbs best is determined by its wave length. Being that plants are green in color, they will more than likely benefit from any color other than green. This being because the color an object appears is the color that that object does not absorb. With this in mind, we wanted to test green light against red light, thinking that photosynthesis would react better with red light wavelengths. Although, our thinking was not completely accurate.…
Ronnie Estes Rocky Mountain Flora March 31, 2015 Milkweed Description Common Milkweed, Asclepias syriaca, is a biennial to perennial herb in the family Asclepiadaceae. This forb usually has a solitary, simple stem, 0.5-1.8 meters (1.5-6 feet) tall, though clumps of multiple stems may be found. Milkweed may also be rhizomatous through the growing season. This may be evident with stems being at different life stages throughout the summer. The leaves are opposite, ovate, and 5-25 centimeters (2-10 inches) long with a short thick pedicel.…
Yet the experiment gave out the 3 minute interval rule. Correct hypothesis: More amount of time under the light will cause the plant to give out more glucose and O2. During the experiment, I learned the role of Sodium Bicarbonate and that photosynthesis can happen very…
Hence, the factor of light intensity could not be investigated as each different amount of fertilizer was exposed to the exact same weather conditions and light intensity. The weather was partly cloudy with lots of instances of rain. In other words, a lack of sunlight was prevalent. This validates the slow growth rate of duckweed. However, during the experiment the weather included humidity.…
its color led to the formulation of this experiment. The experiment utilizes chloroplasts of spinach leaves to test the different color lights’ effects on photosynthesis. Green light is said to be the least effective at driving photosynthesis on the electromagnetic spectrum due to being mostly reflected and transmitted instead of being absorbed. Conversely, red light and white light is more effective at driving photosynthesis (Reece, 2011). Thus, a hypothesis was created stating that the rate of photosynthesis will be greater with a red light bulb compared to a green or white fluorescent light bulb.…
