chloroplasts - -contain the pigment chlorophyll -chlorophyll absorbs red, blue, & violet light ATP - -used to transport E around cells -chemical E stored in the bonds -important bonds between 2nd and 3rd phosphate group -going to lower energy state breaks bonds and releases the energy each molecule during diffusion - -moves randomly -behavior unpredictable -each individual molecule never stops moving dragon fly size - -high O2 levels in carboniferous allowed them to grow big -later in ...
