PHOTOSYNTHESIS:
Storing Energy
8.2
I. Photosynthesis
A. Photosynthesis- Process
of using the suns energy
to make simple sugars
1. Makes glucose
(C6H1206)
2. Glucose can later be
made into complex carbs
to store more energy
I. Photosynthesis
B. The Equation
6CO2 + 6H2O = C6H1206 + 6O2
Carbon Dioxide + Water
Yeilds
Sugar + Oxygen
I. Photosynthesis
C. Consists of 2 reactions
1. Light Dependent
a. Occurs in
thalykoid disks in the
chloroplast
b. See diagram on pg.
222
I. Photosynthesis
2. Light Independent
a. AKA The Calvin
Cycle
b. Occurs in the
stroma of the
chloroplasts
c. See pg. 222 again
I. Photosynthesis
D. Chlorophyll- Pigment that traps
sunlight
1. Cannot absorb green
wavelength of light so it
reflects it!
2. Plants have other pigments
that appear when chlorophyll
is not present (fall)
3. Found in the thalakoid
disks
