You have a large, healthy philodendron that you carelessly leave in total darkness while you are away on vacation. You are surprised to find that it is still alive when you return. What has the plant been using for an energy source while in the dark?-Even though the plant received no visible light, it was able to use the short-wave part of the electromagnetic spectrum (gamma rays and X-rays) to carry out photosynthesis.-While it did have access to light, the plant stored energy in the form of sugars or starch, and it was able to derive energy from the stored molecules during your vacation.-Even though it cannot carry out the light reactions, the plant can still produce sugars because the Calvin cycle does not require light.-When light energy is not available, plants can derive energy from inorganic molecules.

State the relationship between wavelength and energy.Understanding: Visible light has a range of wavelengths with violet the shortest wavelength and red the longest.
List potential responding (dependent) variables for experiments about photosynthesis.Nature of Science: Experimental design- controlling relevant variables in photosynthesis experiments is essential.
