WARM-UP FRIDAY 3/22/13
1)List 1 similarity of virus and bacteria.
2)List 1 difference of virus and bacteria.
PROTISTS AND FUNGI NOTES
Protist and Fungi Notes
OBJECTIVES
1)Compare & Contrast the characteristics of protists & fungi.
2)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)

eating
Green like plants!
Water mold
ANIMAL LIKE PROTIST
Types of Movement1.) 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?A. Harmful: cause disease
EX: malaria & African sleeping sickness B. 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
Kingdom Fungi
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
1) 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
