Chlorophylls: absorb at wavelength 430 nm (blue) and 662 nm (red)
Carotenoids: absorb at wavelength 400 nm (violet) and 550 nm (green)
Why do most leaves have more than one type of pigment, like chlorophyll and carotenoids?
a. Multiple pigments allow the plant to have both photosynthesis and cellular respiration to maximize the amount of energy they capture from the sun.
b. Multiple pigments absorb different wavelengths of light, allowing the plant to capture the maximum amount of energy from the sun.
c. Multiple pigments allow the plants to have different colors of leaves, which allows them to capture the maximum amount of energy from the sun.
d. Multiple pigments allow the leaves to be different colors in the summer and fall, which allows them to capture more energy during the year.
