1 II. Photosynthesis

2 Review of plant cell Have cell walls and chloroplasts.
Chloroplasts are site of photosynthesis

3

4 A. What it is… Plants use sunlight to produce sugar Equation:
6H2O + 6CO2  C6H12O6+ 6O2 (glucose)

5

6 Chloroplasts contain green pigment called chlorophyll
3. How it works… Chloroplasts contain green pigment called chlorophyll Absorbs blue, violet & red light (energy) from sunlight

11 B. Photosynthesis occurs in 2 parts

12

13 1. Light Reaction Light (energy) absorbed by chlorophyll is used to split H2O into H and O atoms ATP is made Oxygen is a “waste product” Occurs in the thylakoids

14

15

16 2. Dark Reaction (Calvin Cycle)
Using ATP, H atoms from part 1 combine with CO2 to make glucose (C6H12O6). Occurs in the stroma
