1 Photosynthesis II Christopherson

2 Photosynthesis Function To produce glucose (food) for producers The formula for glucose: C 6 H 12 O 6

3 Photosynthesis: How? Plants absorb sunlight energy, carbon dioxide and water to make glucose

4 *Where are we?

5 Structure: Chloroplast Stroma: Fluid inside the chloroplast Thylakoid: Group of pigments; absorb sunlight energy Grana: Stack of Thylakoids

6 Photosynthesis Summative Equation (Formula) CO 2 H2OH2O + C 6 H 12 O 6 + O2O2 Sunlight Energy Reactants What is needed Products What is produced

7 The giant sequoia tree is one of the largest trees on earth. It starts as a small seedling and grows into an enormous tree. Five children can stretch their arms across the width of the truck of one of the large sequoia trees! Where did most of the MATTER that makes up the wood and leaves of this huge tree originally come from? Circle the best answer. Sunlight Water Soil Carbon dioxide Oxygen Minerals Chlorophyll Explain your thinking. How did you decide where most of the matter that makes up this tree came from?

8 Do you think Harvard graduates would know the answer to this question? Stop video 1:30

10 Light Dependent Reaction: Location Thylakoid: Location of pigments; absorb sunlight energy

11 Light-Dependent Reaction H2OH2O H O H O2O2 1.Pigments absorb sunlight energy 2. Plants absorb water; break it down into Hs and Os 3. Oxygens combine and leave as oxygen gas O H H

12 Light-Dependent Reaction: Reactants H2OH2O H O H O2O2 Water O H H Hint: Look at arrows going in Sunlight Energy

13 Light-Dependent Reaction: Products H2OH2O H O H O2O2 O H H Hint: Look at arrows going out Oxygen

14 Calvin Cycle: Location Stroma: Fluid inside the chloroplast

15 Calvin Cycle CO2CO2 O2O2 C CO2CO2 CO2CO2 CO2CO2 CO2CO2 CO2CO2 C C C C C O2O2 O2O2 O2O2 O2O2 O2O2 1.Carbon dioxide is released by consumers and producers 2. Producers absorb carbon dioxide; break off the carbon; and release oxygen. 3. Process continues until six carbons are collected 4. The six carbons, the stored energy from the sun, hydrogen, and oxygen ALL combine together to make Glucose C 6 H 12 O 6 C 6 H 12 O 6

16 Why are 6 carbon dioxide molecules absorbed? Need 6 carbons from carbon dioxide to make: C 6 H 12 O 6 Glucose

17 Reactants: Calvin Cycle CO 2 O2O2 C C C C C C O2O2 O2O2 O2O2 O2O2 O2O2 C 6 H 12 O 6 Carbon dioxide

18 Products: Calvin Cycle CO 2 O2O2 C C C C C C O2O2 O2O2 O2O2 O2O2 O2O2 C 6 H 12 O 6 Oxygen Glucose
