  3. Binder check: • Quickly gather your required materials and staple them to your binder check slip.

  4. This week’s schedule • Monday- Algae survey • Tuesday- in BT 103 for Fungi Kingdom survey • Wednesday- Microbial life unit test and binder check (Come here first thing on Wednesday) • Thursday- I won’t see you this day

  5. Due Today: #21- How Protists Differ worksheet #20- Protist lab OR Protist internet activity

  6. Getting Started: Monday, 12-17 • Why is it so important to control the mosquito population? • Why is it considered a benefit for some people in mosquito-ridden areas to have sickle cell anemia???

  7. Today’s agenda: • Turn in work that is due today • Get algae notes from MHS website, my blog in files “Algae” • Complete Algae survey lab- must do this today, we won’t be in room tomorrow • Protists for Dinner worksheet- on front table

  8. Describe the characteristics of algae. • Algae: members of protist kingdom classified by color • Algae form the base of the aquatic food chain as phytoplankton • Algae produces much of the Earth’s oxygen • Algal blooms (masses of algae) may indicate increase in wastes in water, deplete water of nutrients • Uses of algae: medications for ulcers, high blood pressure, arthritis, foods such as sushi wrappings, ice cream, salad dressing, syrup

  9. Describe the types of algae. • Euglenophyta: Example euglena • Has traits of plants: cell wall & chlorophyll • Has traits of animals: move with flagella, respond to light with eyespot

  10. Types of algae. • Phylum dinoflagellata: Dinoflagellates • Have two or more flagella • Several produce toxins when they bloom • Causes red tides: these blooms kill fish

  11. Types of algae • Phylum Bacillariophyta: Diatoms • Marine autotrophs eaten by many other marine animals • Have glassy shells, harvested to use in abrasive cleaners, was used for toothpaste • Store oils giving fish a strong “fishy” taste when they eat them

  12. Types of algae • Phylum Rhodophyta: red algae • Marine seaweed • Attach to rocks at bottom of ocean • Phylum Phaeophyta: brown algae • Most are marine • Commonly called kelp • Grown in kelp “beds” providing shelter for fish

  13. Types of algae • Phylum Chlorophyta: Green algae • Contain chloroplasts which are filled with chlorophyll • Undergo photosynthesis • Usually found in freshwater near the surface • Some have special adaptations for floating called air bladders • Wide variety of forms: filaments, sheets, spherical, and colonies

  14. Quiz 6 • Which algae type is commonly called kelp? a. brown b. green. c. red • Which algae have chlorophyll and are usually found in freshwater? a. brown b. green c. red • Which algae have glassy shells and no flagella? a. brown b. diatoms c. dinoflagellates • Which algae produce toxins when they bloom causing red tides? a. diatoms b. dinoflagellates c. red • How are algae classified? a. shape b. pigment c. movement
