Warm-Up Friday 3/22/13 • List 1 similarity of virus and bacteria. • List 1 difference of virus and bacteria.
Protist and Fungi Notes Protists and Fungi Notes
Objectives • Compare & Contrast the characteristics of protists & fungi. • List real world organisms that belong to kingdom Protista &kindgom Fungi.
Kingdom Protista
Common characteristics of Protists • Domain Eukarya/Kingdom Protista • All eukaryotic • Live in water or moist surroundings • Most unicellular, some multicellular • Autotrophs, Heterotrophs, or both
3 Categories of Protists(based on nutrition) 1) Animal Like- heterotrophs (eat other organisms) 2) Plant Like- autotrophs (contain chloroplast & photosynthesize) 3) Fungus Like- decomposers ( break down dead matter) Didinium eating Paramecium Green like plants! Water mold
Animal Like Protist Types of Movement 1.) Cilia= tiny hair-like projections - used movement & feeding
Animal Like Protist 2.) Pseudopod= “false feet” - cell membrane pushed 1 direction - cytoplasm flows into the bulge - allows protozoan to “drag” rest of cell behind it
Animal Like Protist • Form 2 pseudopods • surrounds & traps food. • Then breaks down food • Uses food vacuole
Animal Like Protists 3.) Flagella= Whip-like structures - used movement
Animal Like Protists • Why do we care? • Harmful: cause disease EX: malaria & African sleeping sickness • Beneficial: food source
Plant Like Protists • Most Algae • Autotrophs (photosynthesis) • Recycle sewage & waste materials • Algal blooms • harmful when overgrown • can deplete nutrients • Low O2 levels kill fish • Red Tides cause illness, paralysis, & death.
Plant Like Protists • Red Algae • Green Algae • Brown Algae
Fungus Like Protist • Heterotrophs • Decomposers • Have cell walls • Not in Kingdom Fungi • can move at 1 point in lives • Example: Mildew, Water Mold, & Slime Mold
Other Protozoans Sporozoans= parasites that feed on cells & body fluids of host Ex. Plasmodium- live in mosquitos
Common characteristics of Fungi • Domain Eukarya/Kingdom Fungi • Eukaryotes • Decomposers • Use spores to reproduce • Need warm, moist places to grow • Examples: yeast, molds, & mushrooms.
Fungi-Obtaining food Hyphae= threadlike tubes that obtain food • Grows hyphae into food • Secretes digestive chemicals • Absorb broken down food
Fungi Reproduction • Fungi release 1,000’s spores • Carried by water & air (asexual reproduction) • Spores land warm, moist area & begin to grow
Yeast • Reproduce by budding • Unicellular • Will grow from “mother” cell • break off • form new cell
Classifications of Fungi • Threadlike= spores look like thread (hyphae) Ex. Bread Mold 2) Sac= spores look like sacs Ex. Yeast
Classification of Fungi 3) Club= spores look like clubs Ex. Mushroom 4) Imperfect= canNOT reproduce sexually Ex. Penicillin
