Chlorophyll's absorption spectrum
A. explains why chlorophyll is green.
B. varies greatly from the action spectrum for photosynthesis.
C. shows that generally all wavelengths of light are able to be absorbed.
D. shows that green light is a necessity for photosynthetic plants.
true/false
Leaves appear green to us because green light is mostly absorbed by chlorophyll a.
A. true
B. false
Which statement is not true?
A. Chlorophyll a is green because it absorbs green wavelengths.
B. Both the red and the blue areas of the spectrum are the most effective for photosynthesis.
C. Nearly all wavelengths of light are used for photosynthesis because of the presence of accessory pigments.
D. Chlorophyll a has two peaks in its absorbance spectrum.
The relative effectiveness of different wavelengths of light on the rate of photosynthesis is shown by
A. an absorption spectrum.
B. an action spectrum.
C. an effectivity reading.
D. the measure of water released.
An action spectrum for a plant has less extreme peaks and valleys than an absorption spectrum for chlorophyll a of the same plant because
A. an action spectrum plots a much more broad spectrum of light.
B. an absorption spectrum takes into account factors that may limit absorption.
C. an action spectrum reflects the presence of other pigments in the plant.
D. an absorption spectrum shows the effectiveness of light on the photosynthetic rate of the plant.
