8.2 READ Qs 1- IDENTIFY two ways cells can use glucose 2- NAME: Check the organism that has chloroplasts  Mushroom  oak tree  earthworm -build complex sugars, carbohydrates, proteins, lipids -energy

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

8.2 PHOTOSYNTHESIS  WHAT YOU WILL LEARN -the two phases of photosynthesis [ describe / diagram ] -the role structures in chloroplast play in photosynthesis -factors that can affect the rate of photosynthesis

 MAIN IDEA -LIGHT energy  CHEMICAL energy -plants absorb LIGHT ENERGY from the SUN to create GLUCOSE- CHEMCIAL ENERGY SONG- PHOTOSYNTHESIS RAP

 OVERVIEW OF PHOTOSYNTHESIS LIST organisms that carry out photosynthesis -autotrophs (plants) LIST the organelle where photosynthesis takes place -chloroplast  1 st -thylakoid / 2 nd -stroma IDENTIFY the chemical equation for photosynthesis: __________ + __________  __________ + ___________ [REACTANTS] light [PRODUCTS] IDENTIFY the energy form used during photosynthesis  chemcial  light IDENTIFY the energy form produced during photosynthesis  chemcial  light 6CO 2 6H 2 O 6O 2 C 6 H 12 O 6

-INTERNAL STRUCTURE: leaf tissue CHLOROPLAST  IMPORTANT STRUCTURES

 IMPORTANT STRUCTURES- CHLOROPLAST CHLOROPLAST -located in the cell of leaves

INNER/OUTER MEMBRANE -phospholipid bilayer -carbs transported across membrane THYLAKOIDS - “coins” -phase I GRANUM- “stack of coins” STROMA- fluid/space -phase II  IMPORTANT STRUCTURES- CHLOROPLAST

 MAIN IDEA

Open Closed STOMATA- openings in leaf allow exchange of water/gases GUARD CELLS- open & close stomata by changing shape Photosynthesis Animation  IMPORTANT STRUCTURES- CHLOROPLAST

 IMPORTANT STRUCTURES- PIGMENTS PIGMENTS -absorb colored light -found in thylakoids of chloroplast CHLOROPHYLL -major light-absorbing pigment in plants -gathers sunlight -absorbs light in all wavelengths [violet-blue] -EXCEPT GREEN / Reflects GREEN

 PHASE ONE: LIGHT REACTIONS PHASE I- NAME: OCCURS IN: STARTS WITH: PRODUCES: light-dependent Light Reactions thylakoids light energy-SUN water -oxygen -H + -ATP / NADPH [energy storing molecules]

 PHASE ONE: LIGHT REACTIONS -sunlight splits water molecules -H 2 O -excites electrons ~ e - gain ENERGY -releases oxygen gas -O 2 [waste product] -H + (protons) needed to make food  ELECTRON TRANSPORT CHAIN -thylakoid membrane  PHOTOSYSTEM II (protein)  ELECTRON CARRIER- NADP + -accepts/transports high energy e - -convert ADP and NADP +  energy carriers ATP and NADPH  PHOTOSYSTEM I (protein)

ELECTRON TRANSPORT CHAIN photosystem II photosystem I

 PHASE TWO: CALVIN CYCLE PHASE 2- NAME: OCCURS IN: STARTS WITH: PRODUCES: light-independent CALVIN CYCLE stroma -CO 2 -ATP / NADPH [energy molecules] -GLUCOSE [6 carbon sugar] -ADP / NADP + [return to light-dependent phase]
