Transcript of Absorption of Light by Chlorophyll A and Chlorophyll B

Absorption of Light by Chlorophyll A and Chlorophyll B
Carotenoids
Carotenoids absorb light in the blue-green and violet region, but yellow, red, and orange wavelengths. They also dispose excess energy.
Chlorophyll A
Chlorophyll A absorbs light in the blue-violet region. It has the shortest wavelengths and the most energy.
Chlorophyll B
Chlorophyll B absorbs red-blue light. The red light that is absorbed has the most wavelength and the least amount of energy.
What gives off the color
The thing that gives plants there color are the chlorophyll. The color that shows on the plant are called the pigments. The three main pigments that we are focusing on are chlorophyll, a, b, and carotenoid
Wavelengths
The wavelength's from the sun decide what color the plant is going to be. If the wavelength is strong, the color of the plant would be in the red region. If the wavelength is weak, the plant would be in the blue region
How this works
Energy from the sun, which is white as seen from the human eye, is a mixture of different wavelengths of light. The plants absorb the sun's energy and reflect the color's off the plant, which we see now.
Definition
The definition of our project is when light is absorbed into molecules called pigments to reflect color off of a plant
Pigments
Pigments reflect the wavelengths they can't absorb,which makes them appear the color that they show.
