Plant Parts Review
• Parts of the Plant
– Chlorophyll: The green pigment found in
all photosynthetic plants.
– Chlorophyll is also responsible for the
green color of the plants leaves.
What is Photosynthesis?
• Photosynthesis is the process by which
plants use energy from the sun to
produce the food they need to survive
as well the by-products that we need
to survive.
The Equation
6H2O + 6CO2
C6H12O6 + 6O2
The Equation “In Words”
6 Water + 6 Carbon Dioxide
Produces
Glucose & 6 Oxygen
Molecules
Is That All?
• In order to make the reaction happen
you must also have a source of
energy.
– The energy needed for photosynthesis is
Sun Light!
Think Of It This Way…
• In order to have any kind of reaction
you need inputs.
– This is due to the Law of Conservation of
Matter: Which states that matter can not
be created or destroyed.
• Our inputs are Carbon Dioxide,
Sunlight and Water.
Think Of It This Way…
• Outputs for this reaction are needed
for the basis of plant and human life.
– The plant used the glucose produced as
a food source. They’ve got to eat too!
– Humans use the oxygen produced to
breath and create energy for their own
bodies.

Why Is This Important?
• As human being we can not survive
without some essentials.
– Food
– Water
– Oxygen
• Plants recycle the carbon dioxide we
produce and turn it into useable
oxygen we need to live.
One Last Thing…
• On a sheet of paper take a minute to
think about the role of photosynthesis
in the plant.
Write three sentences about why
photosynthesis is important for plants
and
three more sentences on what
photosynthesis is important for humans.
