  1. Sea Anemone Research Tying Anemones to Photosynthesis

  2. Background Info about the research Photosynthesis

  3. More Background: Light

  4. Background: Pigments Carotenoid Chlorophyll If we shine ROYIV on carotenoids, what would happen? If we shone GB on chlorophyll, what would happen?

  5. Can’t We all Just Get Along • Symbiosis- When 2 organisms live in close proximity to one another • Mutualism - When both organisms benefit from one another

  6. Sea Anemones and Zooanthellea Sea anemones and Zooanthellea (Photosynthetic Micro-organism) = Mutualism Sea anemone gets food and oxygen Zooanthellea gets protection and calcium

  7. Question #1: What type of pigments do zooanthellea utilize? • How can we isolate the PS pigments? (Chlorophyll treatment vs Carotenoid treatment) • How can we measure PS output of zooanthellea once these treatments are established?

  8. Your Task • In small groups brainstorm an experimental design that we can use to test which type of pigment is being utilized by zooanthellea • Make sure to define your experimental variable (only 1 variable), experimental groups (chlorophyll group + Carotenoid group), and a control group. • How will you assign sea anemones to each of these groups so that the process is random?

  9. DISSOLVED OXYGEN PROBE

  10. Sea anemones and ocean depth • Shallow water • Pros: More light is available (Can rely on PS of zooanthellae to supplement diet) • Cons: Better chance of being eaten or dried up (tides) • Deep water • Pros: Less chance of being eaten or dried up • Cons: Less light (Cannot rely on PS of zooanthellae to supplement diet)

  11. Depth of water and Light availability • As you go deeper into the ocean, you begin to lose different colors of light Surface 5 Meters deep 15+ Meters Deep

  12. Background: Pigments Carotenoid Chlorophyll If we shone RIV on carotenoids, what would happen? If we shone GB on chlorophyll, what would happen?

  13. Question 2: What is the optimal sea depth for a sea anemone??? • Take into account Pro’s and Con’s associated with shallow and deep depths • Take into account type of pigment the zooanthellae is utilizing • Where should we expect to find these sea anemones?
