| 5685119775 | mesophyll | inner tissue of a leaf, contain chloroplasts |  | 1 |
| 5685119776 | stroma | fluid that fills the inner area of a chloroplast |  | 2 |
| 5685119777 | thylakoids | found in stacks in the chloroplast where the light reactions occur |  | 3 |
| 5685119778 | grana | stacks of thylakoids |  | 4 |
| 5685119779 | chlorophyll | pigment that absorbs light energy to power the light reactions of photosynthesis | 5 | |
| 5685119780 | stomata | pores in the epidermis of a leaf that allow water to leave the plant and carbon dioxide to enter it |  | 6 |
| 5685119781 | light reactions | reactions that use light energy, carbon dioxide and water to create ATP and NADPH for use in the calvin cycle; in thylakoid membrane; split H2O to make O2 |  | 7 |
| 5685119782 | NADP+ | an electron acceptor that is reduced and is used to fuel the calvin cycle | 8 | |
| 5685119783 | 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 |
| 5685119784 | carbon fixation | reactions that use co2 to make glucose |  | 10 |
| 5685119785 | absorption spectrum | the range of wavelengths absorbed by a particular pigment |  | 11 |
| 5685119786 | chloroplast | the organelle where photosynthesis takes place |  | 12 |
| 5685119787 | products of light reactions | NADPH + ATP + O2 |  | 13 |
| 5685119788 | reactants of calvin cycle | NADPH + ATP + CO2 | 14 | |
| 5685119789 | water | this molecule splits and allows for an electron to be bumped up to the primary electron acceptor in photosystem II | 15 | |
| 5685119790 | photosystem II | p680; the location of water splitting; forms ATP, O2 and NADPH; O2 is leftover; excess electrons reduce NADP to NADPH; regains electrons by splitting water |  | 16 |
| 5685119791 | p700 | this is the special chlorophyll that is located in photosystem I | 17 | |
| 5685119792 | p680 | this is the special chlorophyll that is located in photosystem II | 18 | |
| 5685119793 | chemoautotroph | organisms that produce their own food using inorganic materials - thermophilic bacteria | 19 | |
| 5685119794 | guard cells | responsible for opening and closing stomata | 20 | |
| 5685119795 | photorespiration | process where o2 gets substituted for CO2 in the calvin cycle | 21 | |
| 5685119796 | c3 plants | these plants have stomata open during the day and are most efficient in cool/moist conditions in normal light |  | 22 |
| 5685119797 | c4 plants | these plants have stomata open during the day, but barely open on hot days, work best in high light/temps, use h20 better |  | 23 |
| 5685119798 | cam plants | these plants only have stomata open at night, convert co2 to an acid that is then broken down during the day - work well in dry conditions |  | 24 |
| 5685119799 | photochemical reactions | reactions occurring in the thylakoid membrane where chlorophyll absorbs light energy and electrons are boosted to higher energy state | 25 | |
| 5685119800 | photosystem structure | pigment molecules bound to proteins; reaction center with primary electron receptor; 2 chlorophyll a molecules; Mg molecule; | 26 | |
| 5685119801 | photosystem I | p700; cycles electrons; independent; only forms ATP through substrate level photophosphorylation | 27 | |
| 5685119802 | photolysis | the O2 derived from oxygen in water during photosynthesis | 28 |
