  • Answer: Correct is the option B. Explanation: If the photosynthesis process decrease, that means that the elodea plant will consume less CO2, and in the time, the snail will continue producing CO2, so at the end of 24 hours, the balance among oxygen and carbon dioxide, will be inclinated to CO2, that is the reason why the test tube turns yellowish, that is the color of the blue bromothymol in ...

  • Examining the interactions between Elodea and snails by detecting the presence of CO 2. Objective: to compare the products of photosynthesis and respiration. Background: In this lab you will use an indicator called bromothymol blue (BTB) to indicate whether CO. 2, carbon dioxide, is present.
  • Bromothymol blue is an acid-base indicator that turns yellow in acidic solutions and blue in alkaline solutions. Carbon dioxide bubbled into water forms carbonic acid. Thus, the more photosynthetic activity, the less acidic and more blue the bromothymol blue solution becomes as the plant uses carbon dioxide during photosynthesis.

  • o When oxygen is present, BTB turns from green to blue. o When carbon dioxide is present, BTB turns from green to yellow. Carbon dioxide-oxygen cycle – the exchange of carbon dioxide and oxygen between plants and animals. o During photosynthesis, plants take in carbon dioxide and water, producing oxygen and glucose.
  • Before beginning the lab, I like to demonstrate to the students how bromothymol blue works. I get 2 erlenmeyer flasks (beakers will work just fine too) and fill them 3/4 of the way full with water. Add enough bromothymol blue for the water to be visibly blue.

  • Problem (in question form): How are photosynthesis and cellular respiration related? Obtain 8 test tubes of equal size/volume and number the test tubes 1-8. Fill each test tube with approximately 30 mL of deionized water. Add enough bromothymol blue (BTB) indicator to solution to each test tube to change the water to a green color (about 3 mL).
  • Jan 05, 2018 · Its bromothymol blue is turning from yellow back to blue, and doing so first in the vicinity of the elodea sprig. This tells us that the solution is changing from acid to base, but the only thing added to that solution to make it acidic was carbon dioxide.
  • Photorespiration, the O2-and light-dependent release of CO2 in C3 plants, is a curious process which inseparable from photosynthesis. Study on the relationship between the two process, which has ...
