1. Name ___________________ Producers, ATP, and Photosynthesis Intro Part 1- Sunlight Powers Life Autotrophs (self feeder) Heterotrophs (other eaters) Feed by the process of Photosynthesis They are also called Producers Most producers are Plants (Land) Others are Algae, Certain Bacteria (Live in Water) They are also called Consumers Can only obtain food by Eating Producers or other Consumers Depend On

2. The products of photosynthesis are the chemical ingredients for cellular respiration, while the products of cellular respiration are the chemical ingredients for photosynthesis. Both producers and consumers harvest energy stored in food by Cellular Respiration

3. Photosynthesis Overview Chloroplast Contain the pigment Chlorophyll (light absorbing pigment) Are located in the leaves’ Mesophyll Which also contain Stoma(ata) Leaf opening which CO2 and O2 enter Veins Storage and delivery in and out of the leaf Fluid Inside chloroplast Called Stroma (like cytoplasm) Suspended in the stroma is the Thylakoid Stacks if thykaloids Granum

4. What makes a chloroplast Green? Different forms of electromagnetic energy have different wavelengths. Shorter wavelengths have more energy than longer wavelengths The peaks represent energy that is absorbed by the chloroplast. Of the visible light striking this chloroplast, the green light is reflected and transmitted more than other colors, which are absorbed. As a result, a leaf containing chloroplasts appears green in color.

5. Photosynthesis occurs in two distinct stage 1.The Light Reaction 2.The Calvin Cycle (Dark Reaction) The light reaction happens on the thylakoid membrane and happens in the presence of sunlight The Calvin Cycle (dark reaction) happens in the stroma and does not require light
