5334790670ChlorophyllGreen Pigment Main photosynthetic pigmnet Absorbs primarily violet-blue and red wavelengths0
5334790675Thylakoidsdense interconnected membranous sacs where the light reactions occur1
5334790678Granastacks of thylakoid2
5334790679Granumsingular of grana3
5334790680Chloroplastsites of photosynthesis4
5334790681Photosynthesisconversion of light energy into chemical energy stored in sugar and other organic molecules5
5334790682Photosynthesis Equation6 CO2 + 6 H2O + light --> C6H12O6 + 6 O26
5334790683Carbon Dioxidesource of inorganic carbon used in photosynthesis7
5334790684Electromagnetic SpectrumElectromagnetic energy which travels in waves8
5334790685ColorsLight we see is reflected off objects and light we don't see is absorbed by objects9
5334790686WhiteAll colors reflected10
5334790687BlackAll colors absorbed11
5334790688Chlorophyll amain photosynthetic green pigment, absorbs primarily violet-blue and red wavelengths12
5334790689Pigmenta molecule that absorbs wavelengths in the visible light spectrum13
5334790690CarotenoidGroup of pigments that absorb blue and blue-green wavelengths, appear orange, yellow, and red14
5334790691Light ReactionsOccur in thylakoid membrane and are also called light dependent reactions15
5334790693PhotosystemConsists of a reaction-center complex surrounded by light-harvesting complexes which split water to create electrons that get transferred to NADP+ to create NADPH and H+ which are used to create ATP16
5334790694Light-Harvesting ComplexContains chlorophyll a, chlorophyll b, and carotenoids (within the photosystem) that will trap light energy for use in the light reactions17
5334790695Photosystem 1Has P700 chlorophyll a in reaction-center complex, thought to have evolved first because it can work alone to create primary acceptors, 2nd of the photosystems18
5334790696Photosystem 2Has P680 chlorophyll a in reaction-center complex, first of the photosystems. splits water into electrons, oxygen, and hydrogen ions19
5334790697CytochromeProtein in the electron transport chain of the photosystems that transfers the electrons to create NADPH20
5334790700Calvin CycleLight-Independent reactions Occurs in stoma, does not use light directly. Uses the enzyme Rubisco to create 2 molecules of G3P which is then either used to create glucose or recycled back into RuBP to restart the cycle21
5334790701RubiscoThe most abundant protein on Earth Carbon Fixation is catalyzed by Rubisco22
5334790702ReductionThe carbon molecules made in Carbon Fixation are reduced into to G3P by adding the negative phosphate from a NADPH that can be used to make glucose or perform other processes23
53347907031 Cycle of Calvin Cycle1 CO2 is fixed 3 ATP are used 2 NADPH are used 1 RuBP is regenerated 6 cycles needed to make 1 glucose molecule24
5334790704C4 PhotosynthesisA method that bypasses photorespiration Happens in corn, sugarcane, and other plants in hot, dry environments Converts carbon dioxide to a 4-carbon intermediary which is then stored in bundle-sheath cells25
5334790706C3 PlantPlants that use the Calvin Cycle without creating carbon intermediaries, take in carbon dioxide through stomata. An enzyme called RuBisCO helps the carbon dioxide combine to make sugar.26
7856816320chlorophyll bPigment that absorbs light in the blue and orange light spectrum. Second major pigment used in plants.27
7856823352CAM PlantsPlants that only open stomata at night. They convert carbon dioxide to malic acid which is then converted back into carbon dioxide during the day for the Calvin cycle28
