1. AUTOTROPHIC NUTRITION

2. PHOTOSYNTHESIS

3. Nutrition
Autotrophic nutrition: (Plants)
Organisms that can synthesize organic compounds from inorganic compounds.
(Make sugar from water)
Heterotrophic Nutrition: (Animals)
Organisms that can not synthesize organic compounds from inorganic.

4. The making of food from Sunlight!!.
Photosynthesis
The making of food from
Sunlight!!.

5. Where does Photosynthesis take place?
Plants?
What gives plants this ability?
Where?
How?
Why?

6. The Chloroplast 2 Essential regions where photosynthesis takes place.
STROMA:
Fluid filled with enzymes.
Where the DARK REACTION takes place
GRANA:
Stacked membranes.
Where the LIGHT REACTION takes place.
Grana
Stroma

7. 2 REACTIONS AND THEIR GOALS
THE OVERALL REACTION
SUNLIGHT
6CO2 +12 H2O C6H12O H2O
ENZYMES
2 REACTIONS AND THEIR GOALS
LIGHT REACTION:
TO PRODUCE OXYGEN FROM WATER
DARK REACTION:
TO PRODUCE FOOD (C6H12O6) FROM CO2 AND HYDROGEN (H2)

11. Photosynthesis and Respiration are two equal and opposite reaction.
To maintain a balance (HOMEOSTASIS) between the environment and the organisms that occupy it.
