11. 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 conditions.
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 finds that the IR treated plants are scorched, the UV
treated plants have wilted, but the white light-treated plants are growing normally.
Which of the following statements is most likely to be correct?
a) Three plants do not provide sufficient replications to draw a conclusion.
b) The wavelength of light does not affect photosynthesis
c) Infrared light contains more energy than other wavelength
d) Wavelength of light is the only variable that has been changed between groups

that deliver blood to capillaries of the organ.
