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)

DidiniumParamecium

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

TYPES OF SPORES

1) Threadlike= spores look like thread (hyphae) Ex. Bread Mold

2) Sac= spores look like sacs Ex. Yeast

TYPES OF SPORES

3) Club= spores look like clubs Ex. Mushroom

4) Imperfect= canNOT reproduce sexually Ex. Penicillin

YEAST

• Reproduce by budding• Unicellular

• Will grow from “mother” cell • break off• form new cell

SUMMARY

Draw a line in your notes for your 3-5 sentence summary.
