5.6 Photosynthetic pigments Flashcards
What is the absorption spectra?
The percentage of each wavelength of light that a photosynthetic pigment absorbs
Usually represented in a graph
What is the action spectrum?
A graph that shows the overall rate of photosynthesis at each wavelength of light
What is photosynthesis?
The process where light energy from the sun is transformed into chemical energy
What are autotrophic organisms?
Organisms that can make energy-containing organic compounds out of inorganic sources
What are plant pigments?
Molecules that absorb light energy over a range of wavelengths
Where are pigments found in plants?
Embedded in the thylakoid membrane within chloroplasts
Why do plants have a variety of pigments?
To widen the range of wavelengths of light they can absorb to ensure maximum rate of photosynthesis
