 8.2 READ Qs 1-IDENTIFY two ways cells can use glucose 2- NAME: Check the organism that has chloroplasts  Mushroom  oak tree  earthworm -Also occurs in bacteria, algae, protists- -build complex sugars, carbohydrates, proteins, lipids -energy  WATCH: https://www.youtube.com/watch?v=g78utcLQrJ4

8.2 READ Qs 3- ILLUSTRATE/LABEL - thylakoid, granum, stroma

8.2 READ Qs 4- EXPLAIN why the leaves of some trees change color in the fall -in the fall plants break down their chlorophyll—the other pigments of the leaf can then be seen

8.2 READ Qs 5-DESCRIBE what photosystem I & II are made of - light-absorbing pigments & proteins

8.2 READ Qs 6-IDENTIFY: Highlight on the diagram the path electrons follow -CIRCLE: What molecule is the electron’s final destination __________________________ - NADPH

 PROVIDE SUPPORTING EVIDENCE: Infer why chloroplasts are found mostly in the leaves of plants. a. The large surface area of leaves allows for maximum light absorption. b. The waxy coating on the surface of leaves helps prevent evaporation. c. Chlorophyll interferes with the xylem and phloem in the stems and trunks of plants. d. The large surface area of leaves allows for contact with oxygen.   -________________________________________ Light is absorbed by the chloroplasts in plant cells -Large surface area provides more exposure of cells
