You discovered a new plant! This plant appears to have two major pigments driving photosynthesis. Here is the absorption spectrum for the two pigments: What can you conclude from this absorption spectrum? dark red light is responsible for a lot of photosynthesis in this plant pigment B is a blue color because it reflects a lot of blue light none of the above are correct all of the above are correct pigment A absorbs a lot of red light this plant is likely a green-yellow color
Sri K.
Why is chlorophyll green? a. It absorbs all wavelengths in the visible spectrum. b. It absorbs wavelengths only in the red portions of the spectrum $(680 \mathrm{nm}, 700 \mathrm{nm})$. c. It absorbs wavelengths in only the blue and red parts of the visible spectrum. d. It absorbs wavelengths only in the blue part of the visible spectrum.
1) What regions, in the visible spectrum, are most strongly absorbed by chlorophyll a and b? 2) Why are the leaves of most plants green? This lab is about spectroscopy.
