5406106435photoautotrophsorganisms that produce their own food using light energy - plants, protists, and algae0
5406106436mesophyllinner tissue of a leaf, contain many chloroplasts1
5406106437stromafluid that fills the inner area of a chloroplast2
5406106438thylakoidsfound in stacks in the chloroplast where the light reactions occur. Disk-shaped sacks.3
5406106439granastacks of thylakoids4
5406106440chlorophyllpigment that absorbs light energy to power the light reactions of photosynthesis5
5406106441stomatapores in the epidermis of a leaf that allow water to leave the plant and carbon dioxide to enter it6
5406106442light dependent reactionsreactions that use water to create ATP and NADPH for use in the calvin cycle7
5406106443NADP+an electron acceptor that is reduced and is used to fuel the calvin cycle8
5406106444calvin cyclethe series of reactions where ATP and NADPH are used to form G3P which is then used to form glucose and other organic molecules9
5406106445carbon fixationreaction that uses co2 to make PGA (involves enzyme Rubisco)10
5406106446absorption spectrumthe range of wavelengths absorbed by a particular pigment11
5406106447chloroplastthe organelle where photosynthesis takes place12
5406106448products of light reactionsNADPH + ATP + O213
5406106449reactants of calvin cycleNADPH + ATP + CO214
5406106450waterthis molecule is split during the light reactions to replace electrons lost from Photosystem II15
5406106451photosystem IIThe location of water splitting. Electrons from here move down an electron transport chain, so that chemiosmosis can produce ATP.16
5406106452p700this is the special chlorophyll that is located in photosystem I17
5406106453p680this is the special chlorophyll that is located in photosystem II18
5406106454chemoautotrophorganisms that produce their own food using inorganic materials - thermophilic Archaea19
5406106455guard cellscells responsible for opening and closing stomata20
5406106456photorespirationprocess where o2 gets substituted for CO2 in the calvin cycle21
5406106457c3 plantsthese plants have stomata open during the day and are most efficient in cool/moist conditions in normal light22
5406106458c4 plantsthese plants have stomata open during the day, but barely open on hot days, work best in high temps; use H20 better23
5406106459CAM plantsthese plants only have stomata open at night, convert co2 to an acid that is then broken down during the day - work well in dry conditions24

5454880644C4 Plant examplesCorn, sugarcane, some turf grasses31
5454887541CAM Plant examplesCactus, pineapple trees, Aloe32
5454891997Non-cyclic Electron FlowElectrons move from water to Photosystem II to Photosystem I (NORMAL Light Reactions)33
5454903927Cyclic Electron FlowElectrons from Photosystem I establish a H+ gradient to make ATP. NADPH is NOT made. Water is NOT split.34
