Elodea was introduced in the mid- 1800’s in the United Kingdom, which spread to Western Europe. Elodea Plant Experiment Conclusion The independent variable effected the dependent because by changing the distance of the light source it was harder for photosynthesis to happen.When the light is farther away there are fewer bubbles.The hypothesis "If the distances 10,20, and 30 Throughout this experiment, one of the variables were the Elodea canadensis plant. In the aquarium they will not spread unless you want them to by planting the cuttings. When in bloom, elodea produces white, three-petaled flowers that float on the surface of the water. Responding Variable- The responding variable in part A of the experiment was the number of bubbles that were produced after each trial. 2) Crush the end of the stem at the site of incision gently. Elodea is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. 2. Submerged portions of all aquatic plants provide … When doing any kind of experiment you want to have a control to compare the results of the final product. St. John, Vallisneria spiralis L. and Potamogeton lucens L. for the plant growth experiment. Identify and explain the control in this experiment. The basic structure of these plants are whirls of leaves around a stem that form a chain of long segments connected to looks like pipe cleaners with usually a diameter of about half an inch or so, depending on the species of elodea plants. Extension Activities 1. The genus Elodea is one of 16 genera that make up the family Hydrocharitaceae and is comprised of 6 species. Pros and Cons of Elodea. Elodea has no known direct food value to wildlife, but is used extensively by insects and invertebrates. All 6 of these plants are native to either North or South America, with Elodea canadensis preferring the cooler regions of northern North America. Over all these days all the bubbles that were once there Elodea,” they are asked to design an experiment which will allow them to demonstrate the use of CO2 by a green plant in photosynthesis, and net production of CO2 (by respiration) in the absence of photosynthetic activity. An experiment that uses aquatic plants shows a student that plants need light for the photosynthesis process. In this experiment I use a plant called Elodea (pond weed). Elodea plants are native to the New World, though a number of species have established themselves as invasive This is a very easy plant to care for in the aquarium and it can even be used as a floating plant to create shady areas. The plant that was grown in the tagged water produced a larger number of oxygen molecules with oxygen-18 than the plant fed the tagged carbon dioxide. Start studying Elodea and Photosynthesis Lab. The effect of light intensity on photosynthesis can be investigated in water plants. Review with students the major differences between plant and animal cells. “…the light intensity increases- i.e. They are adaptable plants and can grow both rooted or floating in a variety of aquatic conditions. permite a las plantas y algas absorber energa a partir de la luz solar. The effects of light intensity on the rate of photosynthesis of the aquatic plant, Elodea were tested. Summary: This lab that we did was to see what would happen to see what would happen to the Elodea plant if we put a different substance in our beakers. 6. However, Cabomba is a more reliable plant and much more effective than the traditional Elodea. They use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Easy. Lesson organisation The work could be carried out individually or in groups of up to 3 students (counter, timekeeper and scribe). One common way is to gather bubbles of gas given off by an aquatic plant. Elodea is native to North America and it is also widely used as aquarium vegetation. The control in this specific lab was the tube with no Elodea plant in it so we could observe what exactly the plant does with the phenol red. If Elodea is an aquatic plant, ... Snails and Elodea will produce more carbon dioxide, causing the water to turn yellow. This is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. Investigating the rate of photosynthesis. Articles. One common way is to gather bubbles of gas given off by an aquatic plant. plant Elodea is placed under different conditions. For the project, a student needs four test tubes or small glass containers with tight-fitting lids, water and elodea, an aquatic plant used in fish tanks. Demonstrate that environmental CO2 is used during photosynthesis in Elodea. Aquatic Plant Growth Experiment. What is meant by the term “carbon fixation”? Purpose: To find out how the Elodea cell looks like and study it under magnification and compare it to different cell parts under a microscope. This has to be one of the easiest plants to propagate and why it is so successful as an invasive plant. This experiment can be adapted so that results can be gathered in 20 minutes or less. How is does a plant use carbon? Save For Later Print. Description. Controlled Variable- The controlled variable in part A of the experiment is the plant that is being used, in this case an elodea, the amount of solvent in … Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). Introduce students to the aquatic plant Elodea by showing them the image of Elodea in an aquarium. In this experiment, we were testing the rate of photosynthesis in elodea. 7. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Elodea produces bubbles when it breathes. Photosynthesis and respiration; Description. 3) Submerge the plant into a test tube filled with 40mL room temperature water and 1g baking soda. The elodea is an aquatic perennial plant. Egeria densa, also known as Elodea densa, is the most popular aquatic plant used to teach photosynthesis in the classroom. 4) Set the test tube on the test tube … For a plant to photosynthesize, it needs carbon dioxide and water and sunlight, a factor of photosynthesis. Demonstrating oxygen formation during photosynthesis can be a tricky process. Updated: February 25, 2008. Classified in the frog’s-bit family (Hydrocharitaceae), Elodea is native to the Americas and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities.It lives in fresh water. This experiment was able to show that the water molecule provided the oxygen molecules that are released into the atmosphere, thus carbon dioxide is primarily used in the formation of carbohydrates. This experiment is needed to be compared with another design experiment prepared by the Tania Lapa. Posted by Ally at 6:56 PM. Short Description. Bromthymol blue is used as an indicator for the presence of CO2 in solution. To see photosynthesis in action, we will observe how a green plant (elodea) uses sunlight to take in CO 2 and release O 2 (control). Use Cabomba or Elodea, which are sold in aquarium shops. // Provide alternate content for browsers that do not support scripting // or for those that have scripting disabled. This trait makes the elodea a useful tool in the study of plant structures and plants' ability to produce energy. Elodea can be found in wet mud along sluggish streams, seepage areas, and marshes. Or, if you have acquired Elodea plants for the Going Further microscope activity, display the plants. Your lab group is asked to design, execute, and analyze an experiment that tries to accomplish the following two tasks: Task A. In This teaching resource introduces Cabomba, a pondweed which is much more effective than the traditional Elodea. Teaching Topics. Use an aquatic plant such as elodea, but plants such as hottonia palustris also work well.
