9 Cards in this Set

  • Front
  • Back
Light - Dependent Reaction
light dependant reactions convert solar energy (lifhgt) to ATP and NADPH (for the Calvin cycle) in the thylakoids (the stacaks of pancakes in the chloroplast)
Light - Independent reaction
are in the calvin cycle in the stroma of the chlroplast converts carbon dioxide to organic compounds (glucose), powered by ATP
Photoautotrophs
organisms using photosynthesis
chemoautotroph
organism not using photosynthesis
Photon
quantum of electromagnetic radiation: a quantum of visible light or other form of electromagnetic radiation demonstrating both particle and wave properties. A photon has neither mass nor electric charge but possesses energy and momentum.
Pigment
coloring substance: a substance that is added to give something such as paint or ink its color. Pigments are often available in the form of dry powders to be added to liquids.
chlorophyll
green plant pigment used in photosynthesis: the pigment in plants that captures the light energy required for photosynthesis. In plants and algae, chlorophyll is contained within numerous minute membranous sacs chloroplasts within cells of the stems and leaves.
Absorbsion Sepectrum
is a graph plotting a pigment's light absorption against wavelength (measure by a spectophotometer)
Photosynthesis
carbohydrate production using light and chlorophyll: a process by which green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen, using light energy trapped by chlorophyll
