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
