1. Do Now! 11/7/16 Go to www.socrative.com Join room name “PETERS216”
Complete the quiz (it is not a graded quiz)
Homework: Gummy Bear labs due Monday

2. Gummy Lab The type of solute did not matter (salt vs. sugar)
We are dealing with the concentration of water
Concentration of water outside the bear vs. inside the bear

3. Distilled Water
No solute outside which means high concentration of water
Lots of solute (sugar) inside, which means lower concentration of water
Which way will water move?

4. Salt Water
Some solute (salt) outside which means high concentration of water
Lots of solute (sugar) inside which means low concentration of water
Which way will water move?

5. Which one had “more” Osmosis?
Salt or Distilled?
Distilled
Why?
There was a higher concentration of water outside in the distilled setup, than the concentration of water outside in the salt setup.

6. Question:
Which of the following statements concerning diffusion and active transport is correct?
Both diffusion and active transport require cell energy.
Neither diffusion nor active transport require cell energy.
Diffusion requires cell energy while active transport does not.
Active transport requires cell energy while diffusion does not.

7. Photosynthesis and Cellular Respiration

8. Terms
Pigment – material that gives something its color based on what type of light it absorbs
ATP – cellular energy and is produced by cellular respiration

9. Terms “troph” = food Autotrophs Heterotrophs Auto = self
Make their own food
Heterotrophs
Hetero = different
Get their food from something else (they have to eat it)

10. Brain Pop
Photosynthesis

11. Photosynthesis

12. Photosynthesis
Process that converts the sun’s energy into chemical energy stored in sugar
Takes place in specialized structures inside plant cells called chloroplasts
Chlorophyll is the pigment that absorbs sunlight.

13. Photosynthesis Reaction
CO2 + H2O + light energy → C6H12O6 + O2
Where does the “light energy” come from?
The food plants make is called glucose (sugar)

14. Photosynthesis Reaction
CO2 + H2O + light energy → C6H12O6 + O2
Carbon Dioxide + Water + Light Energy → Sugar (Glucose) and Oxygen
Either one is fine!

15. How do plants absorb CO2?
Stomata (plural) – pores in the leaf that allow for exchange of gas
Stoma (singular)
CO2 – in
O2 – out
How does the gas move???
Your answer below

16. Brain Pop
Cellular Respiration

17. 11/9/16
Do Now:
What 3 things are required for photosynthesis and what 2 things does it produce?
Homework:
Gummy lab due Monday
Submit Do Now document by Monday in google classroom.

18. Cellular Respiration
Process that turns food into cellular energy (ATP)
Happens in both plant and animal cells
Occurs in the mitochondria
In the folds within (the worm)

19. Cellular Respiration Overview
Overall Reaction:
C6H12O6 + O2 → CO2 + H2O + ATP
Glucose + Oxygen → Carbon Dioxide + Water + ATP
Energy output depends on whether or not there is oxygen
Aerobic Respiration – oxygen present
Anaerobic Respiration (fermentation) - no oxygen present

20. Which one is better? Oxygen rich respiration (aerobic)?
Oxygen poor respiration (anaerobic)?

21. Runner’s Bonk Ever felt tired when running? Why??
Why??

22. Fermentation
The process by which your body produces energy in the absence of oxygen
Produces much less ATP
Makes your muscles very sore the next day
Lactic acid fermentation
Can be used to make alcohol!
Alcoholic fermentation

23. Energy Tally 36 ATP for aerobic vs 2 ATP for anaerobic
Per glucose molecule
Anaerobic organisms can’t be too energetic but are important for global recycling of carbon

24. Cycle
ATP
