1
Q
What is absorption spectra?
A
a graph of the amount of light absorbed by a pigment against the wavelength of light
2
Q
What is action spectra?
A
a graph demonstrating the rate of photosynthesis against the wavelength of light
3
Q
Why do plants have a variety of pigments?
A
so they can absorb a wide wavelength of light
they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs which make their own food using photosynthesis.
