II. Overview of Photosynthesis (4.2)
A. Photosynthetic organisms are producers
1. Producers make their own source of chemical energy

2. Plants use photosynthesis and are producers
a. photosynthesis is process that captures energy from sunlight to make sugars that storechemical energy

b. Uses visible light made up of several colors (wavelengths) of light.

1). Plants use molecule in chloroplast called chlorophyll2). Two main types of chlorophyll

a. Chlorophyll a and chlorophyll b b. Absorb mostly red and blue wavelengths.
c. Plants appear green because reflect green light (not absorbed)

B. Photosynthesis in plants occurs in chloroplasts
1. Most of chloroplast are in leaf cells

2. Two main parts of chloroplasts needed for photosynthesis
a. Grana- stacks of coin-shaped, membrane-enclosed compartments called thylakoids.b. Membrane in thylakoids contain
chlorophyllc. Stroma is the fluid that surrounds grana
