Presentation Transcript

  1. 2/10 • Pick up Protist/Fungi Notes from the back • Take out your warm up sheets and classification chart. • Reminder: • Quiz: Protist and Fungi Wednesday 2/12 • Test Monday, February 17th. *If you haven’t started studying, don’t wait to cram on Sunday!!

  2. Warm up: Which of the following plates has the best Zone of Inhibition? How can you tell?

  3. Kingdom Protista

  4. I. Kingdom Protista – very diverse; any eukaryote that is NOT plant, animal, fungi or bacteria A. General Characteristics 1. Most are – unicellular , few are - multicellular 2. All are – eukaryotes 3. Protists are classified by how they obtain nutrition: a. animal-like: heterotrophs b. plant-like: autotrophs c. fungus-like:decomposers

  5. B. Animal-like protists – some are free-living, some are parasitic (cause Malaria, African sleeping sickness) examples: 1. Paramecium cell membrane (inner) cytoplasm cilia contractilevacuole nucleus

  6. Heterotrophic pumps out water, maintaining water balance in a cell – contractile vacuole (imp. for homeostasis) c. method of movement – cilia Video

  7. 2. Amoeba cell membrane pseudopod contractile vacuole vacuole nucleus cytoplasm

  8. a. false foot – pseudopod b. method of movement–cytoplasmic streaming Video

  9. C. Plantlike protists – examples: 1. Euglena cell membrane (inner) cytoplasm flagellum chloroplast eyespot contractile vacuole nucleus

  10. a. presence of chloroplast – producer, autotroph b. method of movement – flagellum, whip like tail c. eyespot – light sensitive – moves organism toward light for photosynthesis Video

  11. 2. unicellular Algae -- provides a source of nourishment for other organisms 3. red, brown and green algae – multicellular

  12. D. Importance 1. Beneficial a. outer covering of some protists form – hard silica shell = diatoms used in toothpaste and scouring powder b. plankton- food source for other organisms such as snail, clams and fish c. algae – used to make thickener for foods

  13. 2. Harmful a. some protists produce a red pigment, too many protists cause – red tide (affects fish, filter feeders)

  14. b. Mosquito-born infectious disease caused by protists – Malaria c. algal bloom - enormous mass of algae – covers ponds, uses up O2 and kills fish

  15. d. Naegleriafowleri – killer amoeba

  16. 2/11 • Pick up worksheet from the back. • Take out your warm up sheet and your Protists& Fungi Notes • Remember: Protist and Fungi Quiz tomorrow!

  17. Warm up Which diagram represents a system of biological taxonomy showing evolutionary relationships among groups of organisms? Give one example of a plant like protists, and an animal like protists.

  18. Kingdom Fungi

  19. A. General Characteristics Few are unicellular but most are – multicellular They all have cell walls –made of chitin (no cellulose like plants) They are plantlike – can’t move about BUT they cannot make their own food – no chloroplasts, not green All are – heterotrophs They are either: a. Parasites – obtain food from living organisms b. Saprophytes – obtain food from dead organisms 6. Obtain nutrition by – releasing digestive enzymes on organic material and absorbing nutrients

  20. B. Examples • Bread Mold Spores—reproduction hypha (pl. hyphae) Mycelium – absorbs nutrients (NOT roots)

  21. 2. Mushrooms fruiting body Fruiting body spores cap gills stalk mycelium

  22. 3. Yeast - unicellular Ringworm and Athletes Foot (parasites) 5. Symbiotic relationships: Lichens – symbiotic relationship between – fungus and algae Fungus provides moisture, algae provides food – mutualism – both benefit

  23. Mycorrhizae – symbiotic relationship between – fungus and plant roots Fungus helps roots absorb moisture and nutrients, roots provide fungus with products of photosynthesis

  24. Importance: 1. Beneficial a. food—mushrooms, yeast, cheeses b. medicine - penicillin c. decomposers—recycle nutrients back into soil for plants

  25. 2. Harmful: a. plant diseases – smuts, rusts, mildew b. human disease – ringworm, athlete’s foot

  26. Protist Fungus WS • Mark out the following questions: • Protists side • # 9, 14, 16 • Fungus side • 10 on top and 10 in matching

  27. 2/12 Pick up Kingdom Lab worksheets on my desk. Staple together! Do not touch anything on the desks or countertops. 2nd-6th: finish Content Frame Get out your PROTIST LAB – TURN IN TO ALPHA SORTER
