Photosynthesis
What is it?
- Autotrophic organisms
- use energy from sunlight
- to manufacture carbohydrates
- from CO2 + water
-
-
Light
part of electromagnetic spectrum
(D: continuous spectrum of radiation, each part corresponds to a particular wavelength)
-
-
Photosynthetic
Pigments
pigment
D: molecule produced by a living organism that has a colour resulting from the selective reabsorption of different light wavelengths

Absorption Spectrum
-
- plant pigments absorb red + blue ends of spectrum most
- little/no absorption of light in green region
(green light is reflected - why leaves appear green)
Action Spectrum
-
- highest peaks at red + blue ends of spectrum
- show most effective + useful pigments for photosynthetic processes
- lowest point for green region
- of limited value for photosynthesis as plants reflect green light
