Get out ISN we are taking Notes
On Photosynthesis
• Pick up homework Due Monday
• Quiz Friday!!
• Content Obj. Students will be able to
demonstrate comprehension of Photosynthesis
by writing down the equations and labeling the
reactant and products.
• Language Obj. Students will read about the
process of photosynthesis and write what a plant
needs in order to photosynthesize
Cooking Up Some
Photosynthesis Fun!
Think about
this:
What is the gas
that this boy is
breathing out?
What is Photosynthesis?
The process of photosynthesis is a
chemical reaction.
It is the most important
chemical reaction on our planet.
What happens during
photosynthesis?
• Plants capture light energy and use that
energy to make glucose
• Sunlight provides the energy needed by
chlorophyll to change molecules of carbon
dioxide and water into glucose
• Oxygen is also released in this reaction

During photosynthesis how do
plants take in water (H2O)?
Through the roots
How do plants take in carbon dioxide
(CO2)?
Through openings on the underside
of the leaves called stomata.
Click here to see how carbon
dioxide enters the plant
through the leaves!
Name the two reactants in
photosynthesis:
1. Carbon Dioxide
2. Water
What are the
structures in the
leaf where
carbon dioxide
enters the plant?
Stomata

Products of
Photosynthesis
During the process of
photosynthesis plants break apart
the reactants of carbon dioxide and
water and recombine them to
produce oxygen (O2) and a form of
sugar called glucose (C6H12O6).

What 2 things do the
plants do with the
glucose that is
produced during
photosynthesis?
1. Use it as energy for
life processes.
2. Store extra for later
use.
The oxygen is a byproduct that
is not needed by the plant. The
oxygen will leave the plant
through the stomata and enter
Earth’s atmosphere.
What happens to the oxygen
produced during photosynthesis?
What are the products of
photosynthesis?
1. Glucose
2. Oxygen
How does the byproduct
oxygen leave the plant?
Through the stomata!
Putting It All Together
With Light
Let’s Wrap
Everything
Up!
What three things are
needed by plants in
order for photosynthesis
to occur?
What are the reactants of
photosynthesis?
Water
(H2O)
Carbon Dioxide
(CO2)
What are the products of
photosynthesis?
Oxygen!
What else, besides carbon
dioxide and water, must plants
have in order to perform
photosynthesis?
Hint: In our experiment, it
affected the rate of
photosynthesis!
