An energy carrier molecule produced in the light reactions of photosynthesis and used to build sugar in the Calvin cycle.
Organisms that cannot make their own food; they must absorb in injest food.
An organism that can make its own food.
A pathway that traces energy flow from producers through consumers.
A six carbon organic molecule that is used as an energy source by many organisms.
The primary pigment of photosynthesis.
The organelle in which photosynthesis occurs.
Molecules that have no carbon atoms.
Carbon containing molecules that are snthesized by living organisms.
Internal chloroplast membranes; are flat and can be stacked upon one another; location of chlorophyll, accessory pigments and the electron carriers of the electron trasport chain.
An abundant enzyme that combines one molecule of CO2 with a 5-carbon sugar.
An electron carrier that is an electron donor in the Calvin cycle.
The light independendt reactions of photosynthesis during which CO2 is fixed into organic molecules.
The theory that explains why chloroplasts have structural similarities to prokaryotic cells; states that chloroplasts were once independent prokaryotic cells that were engulfed by a eukaryotic cell.
An assembly of pigments that function in photosynthic light absortion and use of molecules.
The set of chemical reactions by which light energy is transformed into chemical energy; which is turn is used to fix carbon from the air into organic compounds.
"Pores" in a leaf that can be open and closed; when open, they permit diffusion fo water vapor and gasses.
The process of integrationof carbon dioxide into organic molecules.
Ligh absorbing pigments that abosorbs light energy and transfer the absorbed energy to chlorophyll.
