Presentation on theme: "Oxygen is a by-product (leftover, waste product)"— Presentation transcript:

1 Oxygen is a by-product (leftover, waste product)
6.2 Photosynthesis pp Photosynthesis Process = plant cells use light energy to rearrange water and carbon dioxide molecules into sugar molecules Oxygen is a by-product (leftover, waste product) Energy now stored in the sugar

2 6 H2O + 6 CO2 + light ----------> C6H12O6 + 6 O2
6.2 Photosynthesis pp 6 H2O CO2 + light > C6H12O O2 6 waters Carbon Dioxides → 1 sugar oxygen molecules Stoma = pores on the surface of plant that gases and water can move through

3 The rate of photosynthesis is affected by environmental factors:
6.2 Photosynthesis pp The rate of photosynthesis is affected by environmental factors: Explain the relationship between CO2 concentration and rate of photosynthesis.

4 The rate of photosynthesis is affected by environmental factors:
6.2 Photosynthesis pp The rate of photosynthesis is affected by environmental factors: Why does the rate of photosynthesis level off even as the light intensity continues to increase?

5 The rate of photosynthesis is affected by environmental factors:
6.2 Photosynthesis pp The rate of photosynthesis is affected by environmental factors: Why might the rate of photosynthesis decrease past a certain temperature? What is the optimal temperature for photosynthesis?

6 6.2 Photosynthesis pp Calvin Cycle = series of chemical reactions in which is CO2 converted into C6H12O6 (sugar) Carbons are rearranged like lego pieces ATP molecules provide the energy to drive it ATP = ENERGY See the diagram on page 117.

7 6.2 Photosynthesis pp Calvin Cycle = series of chemical reactions in which is CO2 converted into C6H12O6 (sugar) See the diagram on page 117.
