Question
d476700026402e32993dd5eb4# 1 0001 Use the absorption spectrum graph and your knowledge of plant pigments to determine which three statements are true. A plant that contains chlorophyll a, chlorophyll b, and carotenoids will reflect more wavelengths than if it contained only chlorophyll a. O The orange and yellow colors of fall foliage are mostly due to carotenoids in the plants. m Different pigments in plant chloroplasts absorb light of different wavelengths. Visible light that is not absorbed by chloroplast pigments determines what color a plant will appear to your eye. 0 If a plant absorbs light in green wavelengths, the plant will appear green to your eye. Submit Submit Provide Feedback Next >Explanation / Answer
Statement - 1 - False
Both chlorophyll b and chlorophyll a absorb light at different wavelengths, which will result in fewer wavelengths of light being reflected.
Statement - 2 - True
Carotenoids are orange, red, and yellow pigments which give colour to plant parts.
Statement - 3 - True
Pigments determine the colour in things by absorbing light of every wavelength except for the light of the wavelengths that we visualize.
Statement - 4 - True
The light that is reflected off the pigments, the light that doesn't get absorbed, is the light that gets picked up by your eye causing the plant to appear a certain colour.
Statement - 5 - False
If it absorbs light in green wavelengths then the plant will not appear green to your eye.
