- Slides: 37
DO NOW ACTIVITY #2 1. Make a photosynthesis book. a) You need 9 blank half sheets of paper b) You need 1 sheet of directions c) Staple the direction sheet last.
DO NOW 2. ACTIVITY How come animals do#2 not need to do photosynthesis? 3. Where does photosynthesis happen in plant cells? 4. Name 2 things that plants produce from photosynthesis. 5. What type of macromolecule do plants
Essential Question: What do plants use for photosynthesis? What do they make? SECTION 6 -1: PHOTOSYNT Learning Target 6. Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.

OVERVIEW Producers: organisms that can make their own food (autotroph)
OVERVIEWProducers (autotrophs) “produce” their own food using energy from the PLANTS sun. _______ are producers.
OVERVIEW Photosynthesis is when plants convert sunlight into sugar photo = light synthesis = to make

LIGHT & PIGMENTS Plants have pigments
LIGHT & PIGMENTS Pigments: light absorbing molecules that capture the sun’s energy
LIGHT & PIGMENTS Pigments: light absorbing molecules that capture the sun’s energy We can see reflected light. We cannot see absorbed light.
ROY G BIV Longest wavelength = Least amount of energy Shortest wavelength = larger amount of energy
Plants look green because chlorophyll reflects green light.
LIGHT & PIGMENTS Chlorophyll is a pigment PLANTS found in _____
LIGHT & PIGMENTS Chlorophyll makes plants GREEN. ____
LIGHT & PIGMENTS 2 types: 1. Chlorophyll a 2. Chlorophyll b
LIGHT & PIGMENTS These pigments absorb red and blue light well. GREEN
IS THE COLOR GREEN BEING REFLECTED OR ABSORBED BY PLANTS?

INSIDE A CHLOROPLAST Photosynthesis takes place in the chloroplasts of plants
INSIDE A CHLOROPLAST Chloroplasts have two parts: 1. thylakoids: saclike membranes found in chloroplasts Many thylakoids = grana pigments capture sunlight (light-dependent reactions)
INSIDE A CHLOROPLAST Chloroplasts have two parts: 2. Stroma: space surrounding the thylakoids
THE CHLOROPLAST
