1 Photosynthesis

2 Light Dependent Reaction vs. Light Independent Reaction

3

4 Light Dependent Reaction Light, water, NADP+, and ADP enter the thylakoid. Oxygen, ATP, NADPH leave Requires light to occur Stores energy temporarily

5 Light Independent Reaction Also known as Calvin cycle ATP, NADPH, and CO2 enter ADP,NADP+, and sugar exit Stores energy for long period of time. Does not need light to occur

6 Which reaction stores energy temporarily? ¿Qué reacción almacena energía temporalmente? Which stores energy for long periods of time? ¿Cuál almacena la energía por períodos del tiempo largos?

7 Gas Exchange Stomata- – Openings in the leafs where gases can enter and leave

8 Which gas enters through the stomata? ¿Qué gas entra a través de los estomas? Which gas leaves through the stomata? ¿Qué gas se va a través de los estomas?

9 Photosynthesis is affected by… Sunlight Water availability CO2 Temperature

10 How could you test whether light intensity effects photosynthesis? ¿Cómo podría usted probar si la intensidad de luz efectúa fotosíntesis?

11 ATP vs. ADP Energy carrier Adenosine Triphosphate vs. Adenosine Diphosphate

12 NADPH vs. NADP Electron carrier Accepts H+ from Water

13 What is the electron carrier for the chloroplast? ¿Cuál es el portador del electrón para el cloroplasto? What is the energy carrier for the reaction? ¿Cuál es el portador de energía para la reacción?

14 Parts of the Chloroplast

15 The light independent reaction takes place in the ___________. La reacción independiente ligera ocurre en el ___________. The light dependent reaction takes place in the ___________. La reacción dependiente ligera ocurre en el ___________.

16 What is a stack of thylakoids called? ¿Qué un apilado de thylakoids se llama? Where does photosynthesis take place? ¿Dónde la fotosíntesis ocurre?

17 Chlorophyll Pigment that traps sunlight Absorbs all colors but green The chloroplast is green because green is reflected
