  1. Photosynthesis B2 2.1, 2.2, 2.3

  2. Photosynthesis • Get into partners • Create a poster, where you depict all the knowledge you know about Photosynthesis: • The equation • Why it happens • How can you tell a plant is doing photosynthesis

  3. Note taking time! • Watch this: Create notes as you watch, and listen carefully. Put your hand up if you want me to pause and discuss something http://www.youtube.com/watch?v=xEhvsXG8cNs

  4. Leaf adaptations • Broad -> L.S.A? • Chloroplasts and chlorophyll = Adapt. • Air spaces = diffusion (CD + O)? • Veins (X + P)?

  5. Structure of a Leaf

  6. Is it just plants that photosynthesize?

  7. No!! So everytime I talk about photosynthesis I mean both plants and algae!! Algae do as well!! =)

  8. Where do they get CO2?

  9. How do they store the glucose??

  10. Starch…the test?

  11. Limiting Factors Birthday girl!! HAPPY BIRTHDAY MARIAM!! Lets say she has cake. She will give cake to everyone… But what if we don’t have all the equipment we need???

  12. Limiting Factors • Whatever is in Short Supply is a limiting factor! • Tell me what do plants need for photosynthesis to happen?? • (1 min group brainstorming)

  13. Photosynthesis Essentials • Light!! • Carbon Dioxide!!! • Temperature

  14. Reward Cake • Let’s have some real cake to reward ourselves!

  15. Limiting Factors

  16. Limiting Factors: Light

  17. Limiting factors: CO2

  18. Limited factors: temperature

  19. Photosynthesis • Two stages!!! • 1. Light dependent stage • 2. Light independent stage When you reject sunshine

  20. Enzymes….

  21. Enzymes

  22. What do molecules do when they are hot?

  23. Let’s be enzymes!!! What happens?

  24. Limited factors: temperature

  25. Limiting Factors

  26. IV? DV?

  27. Respiration Hello my dears!! Plants need to do respiration so they can be like me, MRS GREN BUT also they need respiration for energy to do the formula you will see on the next page…

  28. How do plants use glucose? Sugar+ nitrate ions +mineral ions… = amino acids…. = proteins = enzymes

  29. Algae Also need nutrients, Nitrates minerals

  30. Fats and Oils Plants store fat too!!! So do algae!

  31. Fats and Oils • To store in cells when food is low, a good source of energy • Stronger cell walls! • To store the fat in the seeds, so that the new plant has plenty of food in order to germinate (and grow)

  32. Veins

  33. Moving food

  34. Soluble vs Insoluble

  35. Storage for survival Tubers!

  36. Storage for Survival Bulbs!
