| 619860105 | Photosynthesis | Process by which green plants use sunlight to make organic molecules from carbon dioxide and water., process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches | |
| 619860108 | Autotrophs | Organisms which make their own food, Organisms that use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds | |
| 619860110 | Heterotrophs | An organism that obtains organic food molecules by eating other organisms or their by-products. | |
| 619860112 | Photosynthesis equation | 6CO2 + 6H20 --> C6H12O6 + 6O2 | |
| 619860114 | Reactants of Photosynthesis | Carbon dioxide and Water | |
| 619860116 | Needed for photosynthesis | Light and chlorophyll | |
| 619860118 | Products of Photosynthesis | Glucose and oxygen | |
| 619860119 | Leaf | Site in plant where most photosynthesis takes place in a plant | |
| 619860121 | Palisade layer | Site in leaf where most photosynthesis takes place | |
| 619860123 | Chloroplast | Site in cell where photosynthesis takes place | |
| 619860125 | Thylakoid membrane | Site in the chloroplast where pigments are located and the light reactions take place | |
| 619860127 | Chlorophyll a | Primary pigment which absorbs light | |
| 619860129 | Main events of photosynthesis | 1. Light is absorbed to begin the light reactions. 2. Water is split into protons (H+), electrons, and oxygen. 3 Light energizes electrons. 4. Carbon dioxide is used to make glucose in the Calvin Cycle | |
| 619860131 | Light dependent reactions | 1st stage of photosynthesis. Is dependent on light and uses a series of reactions to create ATP and NADPH for the Calvin Cycle | |
| 619860133 | Green | Color of light which is NOT absorbed | |
| 619860135 | Products of photolysis | Protons (H+), electrons, and oxygen | |
| 619860137 | Fate of electrons in light reactions | Passed to electron transport chains in the chlorophyll | |
| 619860139 | Fate of protons in the light reactions | Used in chemiosmosis and added to NADP+ | |
| 619860141 | Oxygen | This gas is released to the atmosphere or used for cellular respiration | |
| 619860142 | Adenosine Triphosphate | What ATP stands for | |
| 619860143 | Adenosine Diphosphate | What ADP stands for | |
| 619860144 | ATP | high energy molecule which carries energy | |
| 619860145 | ADP | low energy molecule which binds with phosphate to form a high energy molecule | |
| 619860146 | ATP Synthase | enzyme that catalyzes the reaction that adds a high-energy phosphate group to ADP to form ATP | |
| 619860147 | Electron Transport Chain | series of proteins embedded in a membrane along which energized electrons are transported; as electrons are passed from molecule to molecule, energy is released | |
| 619860148 | NADP+ | low energy molecule which binds with 2 electrons and a proton (H+) to form a high energy molecule | |
| 619860149 | ATP | Molecule made in light stage which supplies energy for the Calvin Cycle | |
| 619860150 | NADPH | Molecule made in light stage which supplies protons and electrons for the light independent reactions | |
| 619860151 | Water | This small molecule provides the H+ for making glucose and electrons to replace those lost in photosystem II | |
| 619860152 | Light independent reactions | 2nd stage of photosynthesis. Is NOT dependent on light but is controlled by enzymes | |
| 619860153 | Stroma | The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide in the light independent reactions | |
| 619860154 | Events in Calvin Cycle | Carbon dioxide is taken in and combines with RuBP using Rubisco, PGA is reduced to form G3P, some G3P continues on to become RuBP again while a single G3P molecule will eventually form glucose | |
| 619860155 | Light Intensity, Temperature, and Carbon Dioxide concentration | Factors which effect the rate of photosynthesis |
