This document discusses photosynthesis and cell respiration. It contains sections that engage the reader to think about the processes, explore them through experiments and observations, explain the key components and reactions, extend understanding, and evaluate comprehension. Some key points made are that photosynthesis uses carbon dioxide, water and sunlight to produce oxygen and glucose in plants, while cellular respiration uses glucose and oxygen to produce carbon dioxide, water and energy in animal and plant cells.

1. Photosynthesis and Cell
Respiration

2. Engage your mind
● What process is going on?
● What are the conditions and
materials needed for this
process?
● What are the products of this
process?
● Compare the gas bubbles in both
jars.
● What causes the difference in gas bubbles?
● What is the gas in these bubbles?

3. Explore
● Make a hypothesis about the nature of the
gas found in the bubbles produced.
● Make a prediction
● Design your own experiment

4. Explore
1. Compare Jars (a) and (c).
2. Describe what happens to
the mouse in jars (b) and (d).
3. Deduce the role of the
plant in jar (c).
4. Does this experiment validate
your hypothesis? Explain
5. How can you relate this experiment to our real world?

5. Explain

6. Explain
How does the plant take water?
The plant absorbs the water through its roots by osmosis by transport tissues
called xylem.
How does the plant take Carbon Dioxide?
Leaves contain special structures called stomata that are able to open and
close and absorb Carbon dioxide to cells.
How does it produce oxygen and sugar?
Inside the cell, the chloroplast, that contains chlorophyll pigment,uses the
water and carbon dioxide to make a chemical reactions to produce Oxygen
and Glucose sugar.

7. Extend
How could we purify our earth
from this pollution? How can we
start from our class??

8. Evaluate
You are leaves applying for a job in photosynthesis company. Create
your“resume”, explaining your job qualifications and describing how you will
efficiently get the job done. Descriptions must include key vocabulary such as
stomata, water, carbon dioxide, light, energy,chlorophyll and chloroplast.

9. Engage
But where does the sugar go??
a. The sugar is stored in plant cells.
b. The sugar is extracted from cells to be used
by us.
c. The sugar is used by plant cells to produce
energy.
What do you think?

Lab Demonstration
Materials: Yeast- sugar- water - 2 beakers - spoon - balloon
Procedure:
● Add two spoons of yeast in each beaker.
● Add same amount of water in each.
● Add in one of them one spoon of sugar.
● Observe
● Collect some of the gas produced by a balloon and then empty it in a
small test tube containing lime water.Observe.
Conclude: What is the gas produced by yeast? Justify your answer.

11. Explore
1. How does the presence
of sugar affect the
production of the gas?
2. Yeast are living cells.
What is the name of the process
done in these cells?

12. Explain: Cell Respiration

13. Explain
How is the energy of the sun converted to
energy for cell?
The sugar produced by photosynthesis will
react with oxygen inside the mitochondria of
cells to produce carbon dioxide, water, and
energy in the form of molecules called
adenosine triphosphate (ATP).

14. Extend:
In hospitals, it is not allowed to keep plants
inside the patient’s room, why do you think
doctors forbid it?

15. Evaluate
Do your own mind map to relate
photosynthesis and cell respiration together in
plant cell and animal cell.
