1. Photosynthesis

2. ALL CELLS NEED ENERGY!
ENERGY

3. Living Things Use Energy
How do you get energy?
What about plants?

4. What is photosynthesis?
Process by which plants use sunlight to make their own food
Photo = “light”
Synth= “to make”
Photosynthesis = to make from light.

5. Plant Cell Structure It all starts w/ a leaf….
which have chloroplasts…
filled with chlorophyll.
made of
plant cells….

6. Plant Cell Structure chloroplasts
Plant organelle in which photosynthesis occurs.
Chlorophyll
Green pigment (what makes leaves green)
Inside chloroplasts.
Absorbs light energy from sunlight.

7. The chlorophyll absorbs the sunlight.

8. Photosynthesis CO2 O2 IN OUT IN OUT IN Carbon Dioxide (air) Oxygen
Energy
OUT IN
C6H12O6
(Glucose)
(Sugar)
H2O
(Water)

9. EQUATION FOR PHOTOSYNTHESIS
CARBON
DIOXIDE
WATER
GLUCOSE
OXYGEN
CO2 +
H2O +
C6H12O6 + O2
ENERGY
Plant food.
Used for growth or reproduction
OR stored for later.
Waste

10. Awesome Miss. Eades...
I could care less.
Tell me one reason why I should even care.
What does this have to do with me?

11. Well, it applies to you if you want to keep….
Breathing…..
Eating…..
Living…..

12. Plants and animals need each other to survive.

13. ALL CELLS NEED ENERGY!
ENERGY

14. Respiration
Process by which animal cells release energy from food.

15. RESPIRATION CO2 O2 OUT IN IN OUT Carbon Dioxide (air) Oxygen H2O
(Water)
C6H12O6
(Glucose)
(Sugar)

16. EQUATION FOR RESPIRATION
C6H12O6 + O2
CO2 +
H2O +
ENERGY

OXYGEN
CARBON
DIOXIDE
WATER
In our food
Energy released from food for our bodies to use.
Toxic Waste

17. PHOTOSYNTHESIS RESPIRATION CO2 + O2 H2O + C6H12O6 + C6H12O6 + O2 H2O +
ENERGY
C6H12O6 + O2

RESPIRATION

19. In Summary…

20. In summary, Plants need the CO2 we release…
We need the O2 plants release…
Plants/Animals depend upon each other for survival.
Plants use photosynthesis
Animals use respiration
