The purpose of this experiment was to determine the correlation of light intensity and wavelength on white light, no light, red light and green light color treatments when looking at spinach. The same spinach plant was tested under different light environments (no light, white light, red light and green light). A control cuvette was used to compare the rate of photosynthesis to those of the color transmittance cuvette. Before collecting the data we learned about plants and light absorption. We learned the reason why plants are green is because it emits green color and the other transmitted colors are absorbed by the plant. Using our new information we created a hypothesis for photosynthesis rates in white light versus no light and red light versus green light. In our results we found white light and red light to have the highest rate of photosynthesis present. This information found through our experiment can be used in the coming years to help farmers with the increasing need for food production around the world with fast growing populations.

This process is not only vital to the plants but also for humans and wildlife, as we are reliant on other sources to gain needed amounts of energy to sustain our way of living. If our bodied could not get the need amounts of energy and carbohydrates our organs and vital functions would not have the ability to complete needed processes for life. The purpose of this lab was to see the different changes light color has no the rate of photosynthesis through light intensity and wavelengths absorbed. For this experiment the dependent variable is the rate of photosynthesis and the independent is wavelength and light

    The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…

    The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry, pre-weighted 50 mL beaker.…

    In this study, the effects of both varying temperatures and light intensity upon the photosynthetic rate of spinach leaves were observed. Using the ‘spinach immersion’ technique, the rate of photosynthesis under various conditions was quantified by observing the amount of spinach floating on top of a sodium bicarbonate solution. The sodium bicarbonate solution simultaneously supplied the spinach with carbon dioxide for use in photosynthesis, and caused it to sink. When the leaf underwent photosynthesis and produced oxygen gas, the leaf floated to the surface. It was hypothesized that an increase of either temperature or light intensity would lead to an increased rate of photosynthesis, to a degree.…

    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.…

    Identifying the Photosynthetic Pigments Introduction: This experiment was mostly introduced as identifying the different photosynthetic pigments between the Spinach and Blue-green algae. These two pigments were well used in this experiment and simply finding the appearances. Our group was to experiment both these pigments by the amount of bands there was to use, the distance between one band to another, the band color, the distance pigment migrated from the distance solvent front migrated, and lastly the pigment name. If we add the chromatography liquid to our pigments, then the extract of the pigment begin to separate onto the TLC plate. Materials: 50-mL Beakers Pencil 0.5 mL Blue-green extract 2 Pipet, graduated 4 mL Chromatography solvent 2 pipet, thin-stem 0.5 mL Spinach extract Ruler TLC plate (sheet) Scissors Marker or Wax 2 Watch Glasses Procedure: Label the two 50-mL beakers with group name or number, one beaker “spinach extract” and other “blue-green algae extract” Use scissors to cut the TLC sheet and…

    Investigating the light factors that affect the rate of photosynthesis in Elodea Fatima Hussien Sara House, Lesha Liles, Abigail Saucedo, Melrina Stemn Biology 1441_Sec 017, Monika Pradhan; October 6, 2015 All plants rely on photosynthesis, therefore, we examined the rate at which a submerged plant such as elodea photosynthesized, with different light factors. To do this, the elodea must be completely be submerged in deionized water, later place the two plants under artificial light and natural light. After an hour, elodea has to be removed from the beaker, add three drops of phenolphthalein and then add as many drops of sodium dioxide until the content has turned pink, into the beaker. The amount of sodium dioxide drops that are added to the content after the phenolphthalein will result in the amount of carbon dioxide.…

    Determining The Process of Photosynthesis And Cellular Respiration Using Elodea and Yeast Introduction Photosynthesis is an essential process to life on earth, in which plants and other organisms use sunlight to create food from oxygen, and carbon dioxide. Cellular respiration is when energy in food is released and converted to ATP, which is then used as chemical energy to complete tasks within a cell. This process usually requires oxygen and releases carbon dioxide. Photosynthesis and cellular respiration are similar in some areas and different in others. The purpose of both of the process is to produce energy, but they have different ways of achieving this goal.…

    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.…

    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.…

    Photosynthesis is a plant’s mechanism of converting sunlight and CO2 into energy in the form of organic material (Hohmann-Marriott and Blankenship 2011). Plant respiration is the process of using energy and oxygen to produce CO2 (Gonzalez-Meler et al. 2004). Almost all plants reproduce and respire, therefore it is important to know what factors could affect the rate of photosynthesis and respiration to better understand how plants function. Some research has shown that elevated CO2 concentrations may determine plant productivity by affecting plant physiological processes, and ecosystem structure and functions such as photosynthesis ( Xu et al. 1987).…
