2. Photosynthesis
STANDARD: 1d Students know that chloroplasts capture sunlight energy for photosynthesis

3. The Sun!! Photosynthesis
Where does the energy come from that sustains all life?
The Sun!!

4. Photosynthesis (terms)
Autotroph: “self-feeding” producer, can make its own energy
Heterotroph: “other-feeding” consumer, eats another consumer or autotroph for energy
Like catabolic and anabolic because you can kick it up a bit.
Could add the guy on the right for heterotroph.

6. I. Photosynthesis Using sunlight to make glucose (sugar)
B. Happens in the chloroplast
Chlorophyll
CHLOROPLAST

7. Water, carbon dioxide and sunlight enter
1. Chlorophyll (green pigment) captures the sunlight
2. CO2 enters through the stomata
(openings in the leaf)
3. water enters through the roots

8. D. Glucose and oxygen are produced. 1. Glucose is the plant’s food. 2
D. Glucose and oxygen are produced 1. Glucose is the plant’s food 2. O2 is released through the stomata since it is not needed.

9. E. Equation for photosynthesis: 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2 .

10. Tracking Atoms in Photosynthesis…
Reactants
Reactants
6 CO2
6 H2O
Products
C6H12O O2

11. Photosynthesis Extension
The rate of photosynthesis depends on
temperature
light intensity
CO2 (carbon dioxide) concentration
availability of H2O (water)
Identify

12. What is the independent and dependent variable?

13. Great for screen savers during this week...

14. More screen savers…

20. Cellular Respiration Standard 1d
Students know that mitochondria liberate energy for the work that cells do

21. Storing and Releasing Energy
Do Not Copy
Storing and Releasing Energy
During photosynthesis, plants capture energy from sunlight and “save” it in the form of sugar.
When the cells need energy they “withdraw” it by breaking down the sugar to make ATP
This is called Cellular Respiration

22. I. Cellular respiration
A. Breaking down glucose to make ATP for the cell
B. Happens in the mitochondria
mitochondria

23. C. Glucose and oxygen enter
1. Animals
a. glucose is eaten
b. oxygen is inhaled (breath)
2. Plants
a. make their own glucose
b. oxygen enters through the stomata

24. D. ATP is made for the cell E. CO2 and water are released as waste

25. Glucose oxygen carbon water energy dioxide
F. Equation:
C6H12O6 + 6O2  6CO2 + 6H2O + ATP
Glucose oxygen carbon water energy dioxide
ATP
