We did this by using a Gilson Respirometer and samples of Elodea plant placed in H2O and NaHCO 3 solutions—both of which were operated under lighte d and darkened external conditions—to measure the consumption of CO 2 during photosynthesis and the production of CO 2 during respiration. Censullo Monica Mendoza Saul Longoria... Inhibition Of Direct Light Affects Elodea 's Co2 Production During Photosynthesis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. In order to do this, you will use an . CO2 concentration (BTB color indicator number) 0 6 7 8. 1) Cut a segment of the Elodea plant approximately 8cm with scissors. Phosphoglyceric acid and sugars account for 27% of the label during similar exposures. Part 3: Rate of Photosynthesis Lab Investigation. Photosynthesis-Elodea Lab Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. What is the photosynthesis equation? The rate of photosynthesis varies greatly with changes in wavelengths of light. Bromothymol Blue (which acts as an indicator to show if photosynthesis is occurring). 2. Bio 2 Elodea Lab: Photosynthesis and Cellular Respiration Name_____per____ Objectives: to compare the reactions of photosynthesis and cellular respiration. In this experiment I use a plant called Elodea (pond weed). Add 1-2 drops of bromothymol blue to 15mL of water in a 25 ml graduated cylinder. Its leaves are thin and transparent; most leaves are only two cell layers thick. The standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. They use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Bromothymol blue works because it is able to detect the presence of . Known for its bright green color and leafy stems, E. densais an excellent oxygenating plant, making it perfect for use in fresh… Photosynthesis - Resources: Demonstrating oxygen formation during photosynthesis can be a tricky process. Please check your test tubes and use the data to complete your Data Table and Graph on the back of your Lab Sheet. Assemble the equipment needed to measure the rate of photosynthesis in elodea (water plant). Test Tube Treatment. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. More advanced students can dive deeper into understanding the plant life cycle, chemistry, and biology in our photosynthesis worksheets. An experiment that uses aquatic plants shows a student that plants need light for the photosynthesis process. ©2008 CIBT Photosynthesis and Respiration in Elodea – Student Section Page 2 Purpose: Your lab group is asked to design, execute, and analyze an experiment that tries to accomplish the following two tasks: Task A. Egeria densa, also known as Elodea densa because of its previously incorrect classification in the Elodea genus, is the most popular aquatic plant used to teach photosynthesis in the classroom. Photosynthesis and respiration; Description on Photosynthesis of Elodea. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide. Students will record their data which will be used to conclude whether carbon dioxide was consumed or released by the elodea. Elodea is a leafy flowering plant commonly found in aquariums. This test can be done with and without snails. To observe the rate of photosynthesis under different light conditions. Originally from Brazil, E. densa has spread to temperate regions on all of the continents except Antarctica. Elodea plant, the chemical . Using forceps remove a small leaf from the tip of an Elodea plant and lay … ATP and hydrogen ions and electrons are used in the second stage of photosynthesis, the ‘light-independent reactions’. O. Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. During the ‘light-independent reactions’, carbon dioxide, taken in from the air, is combined with hydrogen and ATP to form a range of organic molecules for the plant.
