Term
| why study photosynthesis? |
|
Definition
largest biosynthetic activity on the planet
70Pg C/year
~1% of total fossil fuel reserves
~10 x our annual energy consumption
produces oxygen required by animal life forms
plants replenish atmospheric content of oxygen every 2000-3000 years |

Definition
electromagnetic energy characterized by wavelength
short wavelength = high energy (UV)
high wavelength = low energy (red)
photosynthesis pigments absorb only certain wavelengths |
