| 7913921049 | photoautotrophs | organisms that produce their own food using light energy - plants, protists, and algae |  | 0 |
| 7913921050 | mesophyll | inner tissue of a leaf, contain many chloroplasts |  | 1 |
| 7913921051 | stroma | fluid that fills the inner area of a chloroplast |  | 2 |
| 7913921052 | thylakoids | found in stacks in the chloroplast where the light reactions occur |  | 3 |
| 7913921053 | grana | stacks of thylakoids |  | 4 |
| 7913921054 | chlorophyll | pigment that absorbs light energy to power the light reactions of photosynthesis |  | 5 |
| 7913921055 | stomata | pores in the epidermis of a leaf that allow water to leave the plant and carbon dioxide to enter it |  | 6 |
| 7913921056 | light reactions | reactions that use carbon dioxide and water to create ATP and NADPH for use in the calvin cycle |  | 7 |
| 7913921057 | NADP+ | an electron acceptor that is reduced and is used to fuel the calvin cycle |  | 8 |
| 7913921058 | calvin cycle | the series of reactions where ATP and NADPH are used to form G3P which is then used to form glucose and other organic molecules including amino acids and nucleic acids | 9 | |
| 7913921059 | carbon fixation | reactions that use CO2 to make glucose |  | 10 |
| 7913921060 | absorption spectrum | the range of wavelengths absorbed by a particular pigment |  | 11 |
| 7913921061 | chloroplast | the organelle where photosynthesis takes place |  | 12 |
| 7913921062 | products of light reactions | NADPH + ATP + O2 | 13 | |
| 7913921063 | reactants of calvin cycle | NADPH + ATP + CO2 | 14 | |
| 7913921064 | water | this molecule splits and allows for an electron to be bumped up to the primary electron acceptor in photosystem II |  | 15 |
| 7913921065 | photosystem II | the location of water splitting |  | 16 |
| 7913921066 | p700 | this is the special chlorophyll that is located in photosystem I |  | 17 |
| 7913921067 | p680 | this is the special chlorophyll that is located in photosystem II |  | 18 |
| 7913921068 | chemoautotroph | organisms that produce their own food using inorganic materials - thermophilic bacteria |  | 19 |
| 7913921069 | guard cells | responsible for opening and closing stomata | 20 | |
| 7913921073 | Electron Transport Chain | A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP. | 21 | |
| 7913921074 | ATP Synthase | Large protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP |  | 22 |
| 7913921075 | Chemiosmosis | Process by which a Hydrogen pump pumps protons into the thylakoid membrane. H+ passively flows through the ATP synthase which leads to the creation of ATP. |  | 23 |
