|
Autotrophs |
Organisms that use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds. |
|
|
Photosynthesis |
Converting light energy from the sun into chemical energy in the form of organic compounds, primarily carbohydrates. |
|
|
Heterotroph |
Organisms that must get energy from food instead of directly from sunlight or inorganic compounds. |
|
|
Light reactions |
Light energy (absorbed from the sun) is converted to chemical energy, which is temporarily stored in ATP and the energy carrier molecule NADPH. |
|
|
Chloroplast |
organelles found in the cells of plants and algae. |
|
|
thylakiod |
System of membrane arranged in flatten sacs. |
|
|
granum |
Multiple layers of stacked thylakoids.
|
|
|
Stroma |
A solution surrounding the grana. |
|
|
Pigment |
Compounds that absorb light.
|
|
|
Chlorophyll |
absorb different colors of lights.
|
|
|
Caroteniods |
Accessory pigments. |
|
|
Photosystem |
2 types, A cluster of pigment molecules in the thylakiod membrane. |
|
|
Primary electron acceptor |
A molecule in the thylakiod membrane, donates the electrons to the first series of molecules located in the thylakoid membrane. |
|
|
Electron transport chain |
Molecules that transfer electrons from one molecule to the next. |
|
|
Chemiomosis |
relies on a concentration gradient of protons across the thylakiod membrane. Recall that some protons are produced from the splitting of water molecules inside the thylakoid. |
|
|
Calvin Cycle |
A series of enzyme-assisted chemical reactions that produce a three-carbon sugar. |
|
|
Carbon fixation |
incorpation of C02 into organic compounds |
|
|
stomata |
plants rapidly lose water water to the air through small pores. |
