absorption
refers to the tendency of certain pigments to cause photos to be absorbed by an object instead of reflecting.
algae
small, photosynthetic organisms which, along with phytoplankton, with produce about 90% of the oxygen produced from all photosynthesis
carotenoid
an accessory pigment, either yellow or orange, in the chloroplasts which absorb wavelengths of light that chlorophyll cannot.
chlorophyll
a green pigment located within the chloroplasts of plants which can participate directly in the light reactions (which convert solar energy to chemical energy)
chloroplast
an organelle found only in plants and in photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water
electromagnetic radiation
energy released from the sun which has both wave and particle characteristics
granum (pl. grana)
a stack of thylakoid membranes within a chloroplast.
light
the portion of the electromagnetic spectrum that has wavelengths detectable by the human eye
NADP+ and NADPH
respectively, the final electron acceptor and the reduced form of that electron acceptor in the photosystems of photosynthesis.
photochemistry
the sun's energy being transformed into electrical energy
photon
the "packets" or quanta of energy which light travels in
photophosphorylation
the process by which ATP is made during photosynthesis
photosynthesis
the process whereby plants, protists, and some bacteria use light, water, and carbon dioxide to make sugars
photosystems I and II
light-harvesting units in photosynthesis, located on the thylakoid membrane of the chloroplast. In photosystem II, light is absorbed by pigments and its energy is channeled to chlorophyll, where it excites an electron. The process is repeated using a different type of chlorophyll molecule in photosystem I.
pigment
compounds that absorb light
thylakoid:
flattened membranes within chloroplasts which house the essential components of the light reaction of photosynthesis
wavelength
the peak-to-peak distance between oscillations
Z-scheme
efers to the fact that when diagrammed, the two electron transport chains in photosynthesis in photosystems I and II have a “Z” shape, on its side
