Photosynthesis Definitions Flashcards
1
Q
Photolysis
A
the chemical process by which molecules are broken down into smaller units through the absorption of light
2
Q
Excitation
A
the jumping of an electron from the ground state(i.e. its lowest energy state) to an immediate higher energy level
3
Q
Absorption spectrum
A
a graph showing the percentage of light absorbed at each wavelength by a pigment or group of pigments
4
Q
Action spectrum
A
a graph showing the rate of photosynthesis at each wavelength of light
5
Q
Limiting factor
A
the factor that limits the reaction rate in any process governed by many factors/restricts the growth of a population
6
Q
Lux meter
A
a device used to measure the amount of light in a space/on a particular work surface
