Which experiment might be performed by a biologist who is interested in determining which plant organs (stems, buds, leaves, etc.) are responsible for sensing photoperiod?
A) Remove the apical meristems from different parts of the plant.
B) Measure auxin levels in different parts of the plant before and after exposure to light.
C) Cover different plant organs with a foil covering to prevent light exposure.
D) Expose the plants to different wavelengths of light.

Question

Covering different plant organs with a foil covering to prevent light exposure would directly test which organs are responsible for sensing photoperiod by selectively blocking light from reaching specific parts of the plant and observing the effects on the plant's development or behavior. This method isolates the variable of light exposure to specific organs, allowing for the determination of which organs sense changes in photoperiod.
