Protist & Fungi Notes
Kingdom Protist Characteristics
1) Domain Eukarya
2) Eukaryotic
3) Live in water or moist surroundings
4) Most unicellular; some multicellular
5) Autotrophs, heterotrophs, or both
3 categories of Protist
1) Animal like= heterotrophs ( eat other organisms )
2) Plant like= autotrophic ( go through photosynthesis )
3) Fungus like= decomposers
Didinium
eating
Paramecium
Types of movement
1) Cilia= tiny hair like projections
2) Psuedopod= “false feet” extension of cytoplasm
3) Flagella= whip like structure
Why do we care?
Harmful= cause disease; example- Malaria
Beneficial= food source for other organisms
Plant like protists
1) Most are algae
2) Autotrophs (photosynthesis)
3) Recycle sewage and waste materials
4) Red tides can cause illness and death in fish and humans.
Fungus like protists
1) Heterotrophs
2) Decomposers
3) Have cell walls
4) Example= slime molds, water molds, and mildew
Other protozoans
1) Sporozoans= parasites that feed on a host
Kingdom Fungi Characteristics
1) Domain Eukarya
2) Eukaryotic
3) Decomposers
4) Use spores to reproduce
5) Examples= yeast, mushrooms, and molds
Hyphae
= threadlike tubes that obtain food for fungi
Yeast
= unicellular; reproduce by budding
Budding
= a cell will grow on “mother” cell and eventually break off
Classification of Fungi
1) Threadlike= reproduce by spores in the hyphae; ex=bread
mold
2) Sac= produce spores in sacs; ex=yeast
3) Club= produce spores in clubs; ex=mushroom
4) Imperfect= cannot produce sexually; ex=penicillin
