Ch 10: Photosynthesis Flashcards
photosynthesis
solar energy -> chemical energy
autotrophs
- self feeders
- sustain themselves w/o eating anything derived from other organisms
- producers
producers
make organic molecules from CO2 & other inorganic molecules
plants are ______
photoautotrophs
photoautotrophs
use light energy to make organic molecules
organisms that do photosynthesis
plants, algae, certain other protists, & some prokaryotes
heterotrophs
get organic material from other organisms
- consumers
- depend on photoautotrophs
chloroplasts
organelle where photosynthesis happens
chlorophyll
green pigment in chloroplasts
light energy absorbed by chlorophyll drives ________ of organic molecules in chloroplast
synthesis
CO2 enters and O2 exits through
stomata
mesophyll
interior tissue of the leaf
- where most chloroplasts are found
thylakoid
connected sacs in chloroplast
thylakoid could be stacked in columns called
grana
stroma
dense fluid
photosynthesis equation
6CO2 + 12H2O + light => C6H12O6 + 6O2 + 6H2O
CO2 splits into
O in water, C6 & O6 in glucose
H2O splits
H12 in glucose, H2 in water, & O2
photosynthesis is a ____ process
redox
H2O is _____ & CO2 is _______
oxidized
reduced
two stages of photosynthesis
light reactions & calvin cycle
light reactions happen in
thylakoid
