1. Converting light energy into chemical energy.
Photosynthesis
Converting light energy into chemical energy.

2. Chapter 8 Vocabulary and Notes
Make a heading in your notebook for Chapter 8 and define the terms below:
ATP
ADP
Chlorophyll

3. What is Photosynthesis?
Photo = “Light”
Synthesis = “To put together”
Photosynthesis = “Putting together with light”
Q: What is being put together in photosynthesis?
Q: Where does photosynthesis occur?

4. The Formula: MEMORIZE THIS! light pigments
6CO2 + 6H2O  C6H12O6 + 6O2

5. Waxy Cuticle
Used by plants to protect their leaves and keep them from losing water in heat or harsh light or gaining too much water in wet climates

6. Leaf Epidermal Cells
Green tight-knit cells that allow light through but don’t contain very many chloroplasts

7. Stomata
Openings on the leaves to let gases like CO2, O2 and H2O vapor pass through

8. Pigments
Chloroplasts: Organelles containing the green pigment chlorophyll. These are the primary pigments used by plants for photosynthesis
Accessory Pigments: Used when chlorophyll is not available (fall, deep ocean, etc)
Carotenoids: Orange and Yellow pigments
Anthocyanins: Red and Purple pigments

9. Veins
Veins contain the vascular tissue (xylem and phloem) that can carry water and sugars to the plants.
Water travels up from the roots and sugars travel down from the leaves.

10. Sunlight reaches the leaf and energizes chlorophyll
CO2 enters through the stoma

11. Glucose (C6H12O6) and Oxygen (O2) are made in the chloroplasts from CO2 and water
O2 is released through stoma
Inside the leaf
Water (H2O) enters the leaf through the stem and veins from the roots.
