FQ: What do plants need to grow?
• Entry Task: make a list of what you
know plants need in order to grow.
Also list any questions that come to
mind about this same questions.
Lets make a class list:
• Sunlight
• Water
• Co2
Focus Questions
• How does a plant use sunlight to grow?
• How does a plant use water to grow?
• How does a plant use CO2 to grow?
Investigative Questions
• How does sunlight affect plant growth?
• How does amount of water affect plant
growth?
• How does CO2 affect plant growth?
How is your group going
to do this investigation?
• Procedure writing planner
– What are your variables?
– Do you have 3 conditions for your MV?
– Do you have a controlled condition/control group?
– Do you have at least 3 CV?
– Did you specifically say to record the RV?
– Did you include multiple trials?

Photosynthesis 8.1
• LT: Today I will…
– Use a model to explain
• ET: What do the three
how ATP releases energy
letters
in
ATP
stand
for?
for the cell to use
– Identify the pathways
that cells use to make
ATP
ATP – Adenosine triphosphate
• ATP is the cells source for quick energy
• It powers all cell functions such as building
proteins and opening ion channels for active
transport
Q: How does it work?
Where do we get all the
ATP our cells need?
• What do we need in our bodies to
to make ATP?
– Stored glucose and fat
• 3 processes that make ATP:
– Cellular/Aerobic respiration:36 ATP
– Lactic acid fermentation: 2 ATP
– Alcohol fermentation: 2ATP
How is this connected to
Photosynthesis?
• We need oxygen and glucose for
cellular respiration
Inside The Chloroplast
Electrons? Carrier Molecules?
• NADP+ = Nicotinamide adenine dinucleotide phosphate
• We call it a “carrier” because like ATP, it traps
a high energy electron in it’s bonds and takes
where it needs to go in the chloroplast
Electrons? From where?
Photosynthesis Overview
• Basically
Light Independent
Photosynthesis
• The location
• The Equation – Reactants and Products
• The Importance
FQ: What do plants need to grow?
Lets revisit these questions from the start of the lab
• How does a plant use sunlight to grow?
• How does a plant use water to grow?
• How does a plant use CO2 to grow?
Data Collection and Discussion
• Now it is time to check our plants and collect
our data from the investigation.
• Once you have your data collected DO NOT
WRITE YOUR CONCLUSION
• Discuss with your group the analysis question
in the lab
Analysis: Does our results
from the lab support our
current thoughts on what
plants need to grow? Why
or Why not?
• With your group discuss your answers to this
question
• Compile your response into one statement on
the whiteboard
FQ: How does photosynthesis convert
light energy into stored chemical
energy in glucose?
Time to apply what we know!
• What is the recipe/steps to this process?
Theatrical Depiction or Song lyrics
• You group with be assigned one of the 2 types
of models to illustrate the steps needed to
convert light energy to chemical energy in
photosynthesis. Your group will need to work
through the following:
– Organizing what you already know/ resources
– Creating a storyline of steps
– Converting those steps into the selected model
Biology
• Use a model to illustrate how
photosynthesis transforms light energy
into stored chemical energy (glucose)
FQ’s:
1. What are the inputs and outputs of
photosynthesis?
2. What are the 2 main processes in
photosynthesis?
3. How can we break these 2 processes
into steps for our model?
Exit Ticket
1. What are the inputs and outputs
of photosynthesis?
2. What are the 2 main processes
in photosynthesis?
3. How has creating your model
helped you learn the above 2?

Cellular respiration
Aerobic
Anaerobic
Glycolysis
NAD+
Krebs cycle
Alcoholic fermentation
Lactic Acid fermentation
FQ: How is burning a marshmallow
similar to our cells burning energy?
• Make some generalizations in your notebook
Use an entire page in your notebook to make this table.
Key Ideas
Mass before burning
Mass after burning
Observations
What is cellular respiration?
• When your cells use glucose
and oxygen to make ATP energy
1st - Glycolysis
• Glycolysis: The splitting
of glucose happens in
the cytoplasm of the
cell
• Result: 2 pyruvic acid
or pyruvate molecules
if Oxygen is not available…
• 2nd - Fermentation: 2
types
– Lactic acid: 2 ATP’s, makes
you sore
– Alcohol: 2 ATP’s, makes
alcohol
If Oxygen is available…
2nd – The Kreb cycle (citric acid cycle)
3rd – Electron Transport Chain (ETC)
Cellular Respiration and Exercise
• LT: Today I will…
– Make a prediction about
how exercise affects
cellular respiration
– Test my prediction
• ET: Review glycolysis,
fermentation, and
cellular respiration.
FQ: Do plants use O2 to covert sugar
into energy and release CO2 as a waste
product as animals do?
