PHOTOSYNTHESIS
LET’S GET INTO THIS…
• I can describe the process of
photosynthesis and write its equation.
• I can explain the transfer of energy that
takes place in photosynthesis.
• I can explain the difference between the
light dependent and light independent
reactions.

What could be better than
a rap song about
photosynthesis?
• List some things that we use in our
everyday lives that are solar
powered (or could be solar
powered).
Solar Power!
• In a way we are solar
powered…explain how???
We run on solar power?
• In one day, enough solar energy reaches
the United States to power the ENTIRE
WORLD’S energy demands for 1 year.
• If this interests you, consider taking
APES next year 
SOLAR POWER
• Producers are organisms that make
their own food (chemical energy) from
inorganic materials.
• Plants do not make energy; they capture
it, store it, and deliver it.
• Energy can be transformed, but never
created or destroyed (1st Law of
Thermodynamics)
Producers
• The process that captures energy
from sunlight to make sugars that
store chemical energy.
• Directly or indirectly, the energy
for almost all organisms begins as
sunlight.
PHOTOSYNTHESIS
• Plants absorb visible light for
photosynthesis.
• Visible light appears white but it is
made up of several colors or
wavelengths of light.
* Chlorophyll is a molecule in
chloroplasts that absorbs some of the
energy in visible light.
CHLOROPHYLL…
SOUNDS MORE LIKE
BOROPHYLL TO ME!
• There are two types of chlorophyll; a and b.
• Together, they absorb mostly red and blue
wavelengths of light, not green.
• Green is reflected, which is why plants
appear green to us!
TYPES OF CHLOROPHYLL
• Photosynthesis can be broken down into 2 reactions:
• 1. Light-dependent reactions capture energy from
sunlight and water to make ATP.
• 2. Light-independent reactions use ATP and carbon
dioxide to make glucose!
TWO REACTIONS IN
PHOTOSYNTHESIS
• 6CO2 +6 H2O -> C6H12O6 + 6O2
