photosynthesis
the process by which plants and some other organisms convert light energy to chemical energy.
oxygen
byproduct of photosynthesis
plants, algae, protists, bacteria
4 photoautotrophs that use photosynthesis
shut down chlorophyll, turn on carotenoids
why leaves change color in the fall
carotenoids don't produce enough ATP
why leaves die and fall to the ground
chemical equation for photosynthesis
6 CO2 + 6 H20 -photosynthesis (light energy) = Glucose (C6 H12 06) and Oxygen gas (O2)
grana
thylakoid stacks
stroma
goo in the chloroplasts, where the carbon cycle takes place
thylakoids
closely stacked, flattened stacks that are the place of light reactions
mesophyll cells
the photosynthetic cells of a leaf
outer and inner membranes
the protective layers of the chloroplast
pigments in thylakoid membrane
how plants get the light needed for photosynthesis?
roots
how plants get the water they need for photosynthesis
stomata (pores)
how plants get carbon dioxide needed for photosynthesis
mitochondria
where glucose goes after the calvin cycle
stroma
where the products of light reactions (ATP and NADPH) go
thylakoids
where the products of the calvin cycle (ADP and NADP+) go
phototrophs and chemotrophs
2 examples of autotrophs
algae
organism that performs the most photosynthesis on earth
chemical energy
photosynthesis converts light energy to _______
false
True or False: photosynthesis occurs only in the day
leaves
special organ of a plant adapted for catching and absorbing sunlight
chloroplasts
special organelles in phototrophic cells that are the place of photosynthesis
chlorophyll
green pigment found on the membrane of the thylakoids
reflects/transmits
what chlorophyll does to green light
carotenoids
pigment in chloroplasts that absorbs sunlight and reflects colors other than green
carbon fixation
when plants and other phototrophs absorb carbon dioxide
cellular respiration
what plants need oxygen for
water
where the oxygen released from phototrophs comes from
sunlight
where energy for photosynthesis comes from
energy decreases
what happens when wavelength increases
light reaction and calvin cycle
two stages of photosynthesis
NADP+ and ADP
products of the calvin cycle
NADPH, ATP, and oxygen
products of light reactions
carbon fixation
another name for the calvin cycle (reorganization of carbon molecules)
1 G3P
1/2 glucose =
electron carrier
another name for NADPH
RuBP
the molecule that starts off and ends the calvin cycle
inverse
type of relation between energy and wavelength
NADP+, ADP+P, and water
reactants of a light reaction
NADPH, ATP, oxygen
products of light reactions
