Question | Answer |
Chloroplast | plastid containing chlorophyll pigment and thylakoid membranes; photosynthesis --- |
Thylakoid Membrane | network of membranes; contains chlorophyll; stacked into columns called grana, high H+ w/i during chemiosmosis --- |
Photosystem | light capturing unit of the thylakoid; center is a single chlorophyll--- |
Photosynthesis | involves reduction of CO2 to carb and release of O2 from water; net reaction is reverse of respiration--- |
Light Reactions | convert solar energy to ATP and NADPH--- |
Cyclic e Flow | series of redox reactions returns electrons to P700; ATP prod --- |
Noncyclic | KEY pathway; high-energy electrons are transferred to electron acceptor NADP+; net result is production of NADPH and ATP / photolysis of water --- |
Dark Reactions | use ATP and NADPH to reduce CO2 to carbs (CO2 fixed to RBP – Calvin cycle) ; product is three carbon PGAL; six turns of the cycle (6 CO2 and 6 RBP) = 12 PGAL; 12PGAL can be converted to 1 glucose + 6RBP; PGAL = prime end product (immediate food nutrient) |
Leaf | site of photosynthesis; several adaptations for efficiency--- |
Waxy Cuticle | reduce transpiration and conserve water--- |
Casparian strip | waxy band in plants that aid in water control--- |
Spongy Layer | moist surface necessary for diffusion of gases--- |
Guard Cells | surround stomata and control its size; open during day; contain chloroplasts thus produce glucose; high glucose content causes cell to swell and open--- |
Nitrifying Bacteria | oxidize ammonia and nitrites to nitrates and use the energy to make glucose; plants use the nitrates to make proteins--- |
Palisade layer | cells found within the mesophyll in leaves of dicotyledonous plants. contain chloroplasts |
