Photosynthesis
and
Cell Respiration
7th Grade Science
DO NOW FRIDAY
• Study for your Law of Conservation of Mass
Open Response.
TODAYS PLAN
• 2.3 Explain how plants give us food in the form of glucose
(carbohydrates).
• 3.1 Describe how animals use oxygen and glucose from
plants in cellular respiration to get energy.
• 3.3 Recognize how plants and animals are
interdependent in the process of photosynthesis and
respiration.
TODAYS DO
• We will complete the Analyzing Data Post-Test.
• We will complete the Law of Conservation of Mass Open
Response.
DO NOW FRIDAY
• Begin work on your Analyzing Data Post-Test.
• Remember to do your best. This is a 100
point grade.
• Do your own work. (Eyes on own paper.)
• When finished, turn your test into the side
cart and pick up an open response and sheet
of notebook paper. Do not write on the open
response. Be sure to label your answer A., B,
C., etc.
• When your open response is complete, turn it
into the side cart also.
• Then get an article and a bag of crayons for
your table from the side cart. Complete the
reading, coloring, and answer the questions
quietly on your own. This is independent
work.

DO NOW MONDAY
• Identify if each picture is showing
photosynthesis or cell respiration.
Explain how you know.
A
B
Carbon dioxide
(CO2)
Water
(H2O)
Energy
(ATP)
TODAYS PLAN
• Construct an explanation that describes photosynthesis’
role in the cycling of matter and flow of energy into and
out of organisms.
• Develop a model to describe how atoms are rearranged
during chemical reactions to new molecules that you use
to grow and use energy.
• TODAYS DO
• We will discuss photosynthesis and cell respiration.
• We will complete a foldable as notes about
photosynthesis and cell respiration.
Photosynthesis Equation
H2 O +
CO2
O2 + C6H12O6
Write the equation and label it on your foldable.
Photosynthesis Uses
• What plants use
• Reactants
o Carbon dioxide (CO2)
o Water (H2O)
o Sunlight
Write the formulas and draw the molecules on
your foldable.
Photosynthesis Makes
• What plants make
• Products
o Oxygen (O2)
o Glucose- sugar (C6H12O6)
Write the formulas and draw the molecules on
your foldable.
Where does Photosynthesis
happen?
• Photosynthesis happens in plants in
their leaves in a cell part called the
chloroplast.
• The chloroplast has a green pigment
called chlorophyll that absorbs
sunlight.
Draw the chloroplast
on your foldable.
Purpose of Photosynthesis
• To make oxygen and food for living
things to get energy
Cell Respiration Equation
C6H12O6 + O2
CO2
+ H2O + Energy
Write the equation and label it on your foldable.
Cell Respiration Uses
• What animals use
• Reactants
o Glucose –sugar- C6H12O6
o Oxygen- O2
Write the formulas and draw the molecules on
your foldable.
Cell Respiration Makes
• What animals breathe out
• Products
o Carbon dioxide (CO2)
o Water (H2O)
o Energy (ATP)
Write the formulas and draw the molecules on
your foldable.
Where does Cell
Respiration happen?
• Cell Respiration happens in the cells of
ALL living things in a cell part called
the mitochondrion.
MITOCHONDRION
Draw the
mitochondrion
on your
foldable.
Purpose of Cell
Respiration
• To break down food to get the energy
out for living things to use.
How do Photosynthesis and Cell
Respiration depend upon one another?
• Photosynthesis uses the things that cell
respiration makes (carbon dioxide and
water).
• Cell respiration uses the things that
photosynthesis makes (glucose and
oxygen).
• Therefore, one could not happen
without the other.
How do Photosynthesis and Cell
Respiration depend upon one another?
• Plants need us for carbon dioxide and
water. We need plants for oxygen
and sugars (glucose).
Draw this
picture on the
back of your
foldable.
