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 soil and watering condition.
3 Arabidopsis plants 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 first finds that the IR treated plants are scorched, the UV treated plants have wilted, but the white light-treated plants are growing normally.
