Notes
PROTISTS 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 Didinium
eating
(eat other organisms) Paramecium
2) Plant Like- autotrophs
(contain chloroplast &
photosynthesize)
3) Fungus Like- decomposers
( break down dead matter)
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?
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
