1. Aim: What structures and raw materials enable an autotroph to accomplish nutrition?

2. Common “Regents Difficulties”
Autotrophic Nutrition (regents definition) -process by which organisms convert inorganic substances into organic substances…
Heterotrophic Nutrition (regents definition) -process by which organisms take in preformed organic compounds………

3. Autotrophs vs. Heterotrophs
Autotrophs – make
their own food.
Heterotrophs – get food from environment
*All Plants
*All consumers
*some protists & monerans

4. What things do plants need to survive?
As lesson develops use light lamp, carbon dioxide, water,
Ex. Elodea

5. Where do plants get energy to make their own food?
SUNLIGHT

6. What else do plants need to make their own food?
Water
Carbon Dioxide
Chlorophyll
Nutrients: Nitrogen
Do phenol red and elodea demo

7. What is the food product they make?
Glucose:
C6H12O6

8. What is this process called?
Photosynthesis

9. What is a waste product of photosynthesis?
Oxygen

10. Oxygen Why is this waste product so important?
We use it for Cellular Respiration!
What is the process of cellular respiration needed for?
Energy production

11. What are some possible consequences of this statistic?
We are destroying our rainforests at a rate of 40,000 square miles a year….
What are some possible consequences of this statistic?

12. Possible effects ?
Not enough oxygen for us…..no cellular
respiration. Lack of energy
b. No food for herbivores
c. No food for carnivores
d. Entire food chain collapses
e. Global warming (too much CO2)

13. Where in plants does photosynthesis take place?
Leaf

14. Describe the structure of a leaf………
Wide and Flat
Why would a leaf have this type of structure?
To capture
LIGHT ENERGY

15. LEAF PARTS: Label the leaf below using the following terms:
BLADE STALK VEINS
BLADE
STALK
VEINS

16. What kind of leaves are these?
SIMPLE

17. What kind of leaves are these?
COMPOUND

19. What organelle in the cell does photosynthesis take place?
CHLOROPLAST

20. What is the chemical reaction?
enzyme
6H2O + 6CO > C6H12O6+ 6O2
Why?
chlorophyll
= Storage form of sugars

21. How are we different from plants?

22. Summary Questions
Why do plants turn white from a lack of sunlight? Explain
Some people have said that talking to your plants will help them to grow. Do you agree with this theory? Why or Why not?
Chlorophyll breaks down without sunlight.
Carbon Dioxide from your breathe helps
the plant grow.
