Elodea Photosynthesis Lab. ± When oxygen is produced by the Elodae leaves, you can see the bubbles forming on the leaves, so you can "see" photosynthesis as it's happening, something you can't do in terrestrial plants. __________________________________________________________________________________________________________________________________________________________________ What is the purpose of the control? Bromothymol Blue (which acts as an indicator to show if photosynthesis is occurring). (If it stays blue, the BTB is too concentrated; if it turns yellow, the BTB is too diluted.) Demonstrate that environmental CO2 is used during photosynthesis in Elodea. 742 Public Schools Just make sure that they are kept in cool water until used. ™! In order to do this, you will use an Elodea plant, the chemical Bromothymol Blue (which acts as an indicator to show if photosynthesis is occurring).
