1. Plants VS Animals

2. Despite both being eukaryotic cells, plant cells and animal cells have some major differences
PLANT VS. ANIMAL
PLANT CELLS
Cell wall to provide support
Chloroplasts, makes food
Very large vacuole
Generally a well defined shape
ANIMAL CELLS
Centrioles, aid cell division
Small vacuoles
Irregular shaped

3. Refresher: What organelle provides the cell with energy?
What organelle is the site of photosynthesis?

5. Photosynthesis – our favorite thing in biology ever
What happens?
Energy from sunlight converts water and carbon dioxide to glucose (sugar) and oxygen
Where does it happen?
In plants (and green algae) inside the chloroplast

6. Chloroplasts
The site of Photosynthesis, which plants use to make food from sunlight, Carbon Dioxide and Water.
Only found in plants, and algae

7. Photosynthesis – the reaction
6CO2 + 6H2O  C6H12O6 + 6O2

8. How does Photosynthesis Work?
Light Energy is captured by chlorophyll in the chloroplast, which is used to combine Carbon Dioxide and Water to make Glucose and Oxygen (as a byproduct).

9. Transfer to consumers
In order for consumers to receive the energy from the sun to fuel their own cell processes, they must eat producers or other consumers that already have this energy in the form of glucose.

10. Cellular respiration What happens? Where does it happen?
Glucose is converted into usable energy for the cell (ATP)
Where does it happen?
In ALL EUKARYOTES inside the mitochondria.. Both plants and animals

11. What is the process?
Oxygen is combined with Glucose in the Mitochondria. ATP Energy is produced as well as Water and Carbon Dioxide (as a byproduct).

12. Cellular Respiration – the reaction
C6H12O6 + 6O2  6H2O + 6CO2 + ATP

13. What is ATP? Cellular energy Used for all cell activities
Adenosine triphosphate
Break one bond to release energy
Ex: Muscle cell contracting

14. Summarizer:
How are photosynthesis and cellular respiration dependent on one another?

15. Photosynthesis and Cell respiration in action:
Bromothymol blue: indicator substance that changes color based on presence of CO2 and O2
bromothymol blue + CO2 = green color
bromothymol blue + O2 = blue color
Elodea is an aquatic plant species
