Protists and Fungi
2
Characteristics of Kingdom Protista

• Most diverse group
• Eukaryotic cells
• Some autotrophs, some heterotrophs
• Unicellular and multicellular

3

Kingdom Protista Types

• Algae-Plant like Protists, autotrophs
• Protozoans-Animal like Protists, all unicellular,
  heterotrophs
• Fungus like Protists- move at some point in their
  lives

4
Algae

• Classified by color
• Euglenoids
• Golden Algae
• Green Algae
• Brown Algae
• Red Algae
• Fire Algae

5
Euglenoids

• Autotrophic and heterotrophic
• Flagella- hunt like an animal
• Chloroplasts- make own food
• like plant

Golden Algae
Diatoms- two shells

More Diatoms

Green Algae
Unicellular and multicellular Contain
chlorophyll Plant ancestor Examples spirogyra,
ulva- sea lettuce, volvox- colonial algae
10
Green Algae
Spirogyra
11
Green Algae
12
Brown Algae

• Seaweed and kelp
• Has air bladder- gas-filled structures that keep
  algae floating near the surface for photosynthesis

13
Red Algae
Feathery and fragile bodies Live in deep
oceans
14
Fire Algae
Dinoflagellates Bioluminescence- glow when
disturbed in the water
15
Fire Algae

• Red tide- uncontrolled growth (algal bloom) of
  dinoflagellates. Release poisons that kill fish

16
Protozoans

• Classified by method of movement
• Rhizopods
• Ciliates
• Flagellates
• Sporozoans

17
Rhizopods
Amoeba
Move by pseudopodia- false feet- extends plasma
membrane around prey forming a pocket
18
Label the parts of the amoeba

• Contractile vacuole- used to pump out excess water

Ciliates
Move by beating cilia
Stentor

micronucleus
macronucleus
Oral groove
Anal pore
21
Flagellates
Move by flagella
Trypanasoma
22
Sporozoans
No method of movement Must live in food supply to
survive Many are parasitic
23
Fungus Like Protist
Plasmodium- colorful slime molds found oozing on
rotting logs in forests
Slime mold
24
Kingdom Fungi Review

• Classified by the shape of the structure that
  holds the spores
• Saprophytes- feed on dead matter
• Some parasites
• Stationary like plants/Heterotrophic like animals
• Absorb food through cell walls

Fungus and algae Mutualistic relationship-algae
provides food and fungus provides protection and
moisture
