3. The ability to do work or cause change
ENERGY
The ability to do work or cause change

4. How do living things get energy?
By burning fuel
Cars burn gasoline (non-living)

5. How do living organisms get energy?
Living organisms “burn” glucose (simple sugar)
This is called CELLULAR RESPIRATION

6. Where does glucose come from?
Animals ingest food
Carbohydrates

7. Where does glucose come from?
Plants are different
Plants make their own food in a process called PHOTOSYNTHESIS

8. Food making process in plants and other organisms that use sunlight
PHOTOSYNTHESIS
Food making process in plants and other organisms that use sunlight

9. Only occurs when light is shining on the plant
PHOTOSYNTHESIS
Only in plants
Only occurs when light is shining on the plant
At night, plants use cellular respiration for energy

16. Illuminating Photosynthesis

17. Chloroplasts and Photosynthesis

19. Photosynthesis takes place in the (leaves / root) of a plant.
(Sunlight / Water) supplies the energy a plant needs to make sugar.
Carbon dioxide enters the plant through the (xylem / stomata).
The cell parts of green plants where photosynthesis takes place are (mesophyll / chloroplasts).
A plant gives off (oxygen / carbon dioxide) as a byproduct during photosynthesis.
Water is taken into a plant through the (roots / veins).
An organism that gets food by eating other organisms is (an autotroph / a heterotroph).

20. Cellular Respiration
A chemical reaction that takes place in the mitochondria
This reaction releases energy for the cell to use

25. Cellular Respiration Equation
C6H12O6

26. What are the byproducts of cellular respiration?
C6H12O O  CO H2O + ENERGY Glucose Oxygen  Carbon dioxide Water + ENERGY
What are the byproducts of cellular respiration?
Answer: Carbon dioxide, water and ENERGY!
What sugar is used for cellular respiration?
Answer: glucose

27. Why does the body carry out cellular respiration?
C6H12O O  CO H2O + ENERGY Glucose Oxygen  Carbon dioxide Water + ENERGY
Why does the body carry out cellular respiration?
Answer: to produce energy
What substances does the body need to carry out cellular respiration?
Answer: oxygen and glucose
