Photosynthesis and cellular respiration are opposite but complementary processes. Photosynthesis uses carbon dioxide, water, and sunlight to produce glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy in the form of ATP. Students are tasked with creating a poster comparing and contrasting photosynthesis and cellular respiration by including chemical formulas, drawings, and labeling reactants and products.

1. Bell-Ringer
From memory, draw a prokaryotic
cell, a eukaryotic animal cell, and a
eukaryotic plant cell.
From memory, label and define
organelles.

2. OBJECTIVE 9B
•COMPARE THE REACTANTS
AND PRODUCTS OF
PHOTOSYNTHESIS AND
CELLULAR RESPIRATION.

3. QUICK REVIEW
Homeostasis = Stability
•Stable internal conditions
•Temperature, water content, chemical
content, etc.

4. Metabolism:
• The sum of all chemical reactions in an organism.
• Think Energy (ATP)

5. Photosynthesis:
Plant Energy
• Photo = “Light”
• Synthesis = “Putting Together”
• Light energy is converted to
chemical energy in chloroplast!
• Chemical energy is used to make
organic compounds

6. Photosynthesis
•Carbon Dioxide + Water
Glucose + Oxygen
• 6CO2 + 6H20
C6H12O6 + 6O2

7. Cellular Respiration:
Animal Energy
• Organic compounds are converted to chemical energy
(ATP) in mitochondria!

8. Cellular Respiration
Oxygen + Glucose
enzymes
Carbon Dioxide + Water + Energy
6O2 + C6H12O6
6CO2 + 6H2O + ATP energy

9. Cellular Respiration
6O2 + _____
enzyme
6CO2 + 6H2O +
_____

10. Photosynthesis and Cellular
Respiration Poster
• Create a Photosynthesis Poster (front) and a Cellular
Respiration Poster (back)
• Title each page
• Include the chemical formulas and pictures/drawings
of each compound
• Insert your favorite C6H12O6 (sugar) and favorite use
of energy
• Use slide #5 and slide #8 as an example
• MUST USE A MINIMUM OF 4 COLORS!

11. Exit Ticket
•On one side of your poster write in
one sentence one similarity between
photosynthesis and cellular
respiration.
