1. The Sun!! Photosynthesis
Where does the energy come from that sustains all life?
The Sun!!

3. Photosynthesis Using sunlight to make glucose (sugar)
Happens in the chloroplast
Chlorophyll
CHLOROPLAST

4. Water, carbon dioxide and sunlight enter
1. Chlorophyll (green pigment) captures the sunlight
2. CO2 enters through the stomata
(openings in the leaf)
3. water enters through the roots

5. Glucose and oxygen are produced. 1. Glucose is the plant’s food. 2
Glucose and oxygen are produced 1. Glucose is the plant’s food 2. O2 is released through the stomata since it is not needed. Plants use the food (glucose) to grow and store energy (starch)

6. Equation for photosynthesis: 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2 .
