1. Aim: How do autotrophic and heterotrophic nutrition differ?

2. Autotrophs vs. Heterotrophs
Autotrophs – make own food
Heterotrophs – get food from environment

3. 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………

4. Why is it called PHOTO …….SYNTHESIS?
Photo …….. Light
Synthesis…….. To make
Photosynthesis: The process where light energy is converted to useable energy
(glucose)

5. Why is photosynthesis important?
It produces glucose and oxygen which are needed to carry out cellular respiration

6. Where in plants does photosynthesis take place?
Leaf

7. What organelle in the cell does photosynthesis take place?
CHLOROPLAST
Contains a pigment called chlorophyll

8. Chlorophyll does not absorb green light!!!
Why are plants green?
Chlorophyll does not absorb green light!!!

9. What do plants need in order to maintain homeostasis?
Light energy
From the sun
Chlorophyll
pigment
Enzymes

10. Raw materials end products
Raw materials: what is being used (left side of the arrow)
End products: What is produced (right side of the arrow
Raw materials end products

11. Raw materials of photosynthesis:
water (H2O) and CO2 (Carbon Dioxide)
The end products of photosynthesis:
C6H12O6 (glucose) and O2 (oxygen)

12. Chemical Equation for photosyntesis
enzyme
6H2O + 6CO > C6H12O6+ 6O2
Why is glucose and oxygen an important end product?
They are used for cellular respiration

13. Where do plants get energy to make their own food?
SUN
