QUESTION
You have a large, healthy philodendron that you carelessly leave in total darkness while you are 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?
A. When light energy is not available, plants can derive energy from inorganic molecules.
B. 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.
C. 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.
D. Even though it can't carry out the light reactions, the plant can still produce sugars because the Calvin cycle doesn't require light.
E. None of the above.
The photoelectric effect:
a.
results in the ejection of electrons by light at high intensity.
b.
is the phenomenon that electrons will only be ejected from the surface of a metal by light that has some minimum brightness, no matter what the frequency.
c.
was explained by Max Planck.
d.
describes the phenomenon of producing light by shining a beam of electrons on a metal surface until it glows.
e.
is the phenomenon that electrons will only be ejected from the surface of a metal by light that has some minimum frequency, no matter how bright or how long you apply the light at a lower frequency.
