Davis Craig | Beststudy Academics ([email protected]/[email protected]) TEAS 7 SCIENCE (97% Correct) 1. A student investigating the importance of wavelengths above and below the visible spectrum for photosynthesis sets up an experiment as follows over a 2-month period,all with illumination at 1-meter distance from plants grown with the same sol and watering conditions  3 Arabidopsis plant exposed to ultraviolet light (UV)  3 Arabidopsis plants exposed to infrared light (IR)  3 Arabidopsis plants exposed to white light At the end of the experiment, she finds that the IR treated plants are scorched, the UVtreated plants have wilted, but the white light created plants are growing normally.
