|
autotroph |
an organism that uses the sun to make it's own food |
|
|
photosynthesis |
a process used by autotrophs in order to make the food for themselves |
|
|
heterotroph |
organisms that rely on other organisms to make energy for them. example: Animals |
|
|
light reactions |
Light energy from the sun turned into a chemical energy. temporarily stored as ATP. |
|
|
chloroplast |
an organelle found in plants and aglae that sucks up light and turns it into energy |
|
|
thylakoid |
a membrane found in the chloroplasts that contains the components for photosynthesis |
|
|
granum |
a stack of thylakoids |
|
|
stroma |
one of many openings in a leaf or stem of a plant that enable gas exchange to occur |
|
|
pigment |
a substance that gives another substance or a mixing color |
|
|
chlorophyll |
the green pigment within the chloroplasts |
|
|
carotenoid |
an orange pigment within the chloroplasts that only is visible during the fall season |
|
|
photosystem |
a cluster of chlorophyll and other pigments that harness light energy in the chloroplasts |
|
|
primary electron acceptor |
an acceptor of electrons last from chlorophyll a; found in the thylakoid membrane |
|
|
chemiosmosis |
in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP |
|
|
electron transport chain |
a series for molecules found in the mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane |
|
|
Calvin Cycle |
a biochemical pathway of photosynthesis where carbon dioxide is converted into glucose using ATP |
|
|
carbon fixation |
the synthesis of organic compounds from carbon dioxide, such as in photosynthesis |
|
|
stomata |
the liquid around the thylakoids |
