Photosynthesis Cellular Respiration Slide 3 Autotrophic Organisms
Use light energy to make their own foodUse light energy to make
their own food Provide ULTIMATE SOURCE OF ENERGY for all living
thingsProvide ULTIMATE SOURCE OF ENERGY for all living things All

bacteria Slide 4 Heterotrophic Organisms CANNOT use light energy to
make foodCANNOT use light energy to make food Obtain food energy by
CONSUMING their foodObtain food energy by CONSUMING their food

ADP: Chemical energy for cells ATP:ATP: Adenosine
TriPhosphateAdenosine TriPhosphate How many phosphates in ATP?How
many phosphates in ATP? 3; Tri means 3!3; Tri means 3! Main source
of cells energyMain source of cells energy Fully charged

ADP: Chemical energy for cells ADP:ADP: Adenosine
DiPhosphateAdenosine DiPhosphate How many phosphates in ADP?How
many phosphates in ADP? 2; Di means 2!2; Di means 2! ADP becomes
ATP by adding a PADP becomes ATP by adding a P Half-charged

Energy released from ATP when it loses a phosphate (use the
battery)Energy released from ATP when it loses a phosphate (use the
battery) ATP ADP + ENERGY ATP ADP + ENERGY Energy (FROM BREAKING
DOWN GLUCOSE) is used to add a phosphate to make ATP from ADP
(charge the battery)Energy (FROM BREAKING DOWN GLUCOSE) is used to
add a phosphate to make ATP from ADP (charge the battery) ADP ATP

wavelengthsSun emits energy in different wavelengths The shorter
the wavelength, the more energy it hasThe shorter the wavelength,
the more energy it has According to chart, which wavelength is
shortest?According to chart, which wavelength is shortest?

guard cells are open:When guard cells are open: Carbon dioxide can
move in freelyCarbon dioxide can move in freely Oxygen can move out
freelyOxygen can move out freely Water can exit the leaf, without
the leaf drying upWater can exit the leaf, without the leaf drying
up During humid conditionsDuring humid conditions When guard cells
are closed:When guard cells are closed: Photosynthesis rates slow
downPhotosynthesis rates slow down Water is kept in the leaf, to
prevent water lossWater is kept in the leaf, to prevent water loss
