Biology4-2 Flashcards
reactants of photosynthesis
light, carbon dioxide, and water
products of photosynthesis
carbohydrates and oxygen
reactants of the light reactions
H20, light, NADP+, ADP+P
products of the light reactions
ATP, NADPH, O2
reactants of the Calvin Cycle
CO2, ATP, NADPH
products of the Calvin Cycle
sugar, NADP+, ADP+P
Why must photosynthesis produce sugar instead of directly outputting ATP or NADPH to the cell?
ATP and NADPH cannot be stored for later use
stomata
hole in leaf that allows H2) and O2 to move out and CO2 to move in
cuticle
waxy outer layer that prevents water loss
guard cells
open stomata when there is H2) present
palisade mesophyll
contains cells with chloroplasts
spongy mesophyll
provides air space within leaf
vein
transports H20 and nutrients to plant
xylem
transports nutrients within plant veins
phloem
transports water within plant veins
upper/lower epidermis
outer cell layers of the leaf
bundle sheath
surround vein in C4 plants
outer membrane
outer phospholipid bilayer of a chloroplast
intermembrane space
open region between the two phosopholipid bilayers of a chloroplast
inner membrane
inner phospholipid bilayer of a chloroplast
stroma
aqueous fluid (comprised mostly of water) that makes up the interior of a chloroplast; where the Calvin Cycle occurs; contains enzymes needed for Calvin Cycle, cpDNA, cpRNA, and cp ribosomes
Where does the Calvin Cycle occur?
in the stroma
lumen
space inside a thylakoid
thylakoid membrane
contains chlorophyll pigments; where light reactions occur
Where do the light reactions occur?
in the thylakoid membrane
granum
stack of thylakoids
