1. Kingdom Protista
What are the groups of multicellular plant-like protists?
What are the similarities and differences between the fungus-like protists?

2. Multicellular Plant-Like Protists
Brown algae (phylum Phaeophyta)
Contain chlorophyll a and c and fucoxanthins
Marine
Found in cool, shallow waters of temperate and arctic areas
Examples: Kelp, Sargassum, and Fucus

3. Multicellular Plant-Like Protists
Green Algae (phylum Chlorophyta)
Contain chlorophyll a and b
Found in fresh and salt water
Unicellular Green Algae
Chlamydomonas
Colonial Green Algae
Spirogyra forms long, threadlike colonies called filaments
Volvox consists of 500 to 50,000 cells arranged to form hollow balls

4. Multicellular Plant-like Protists
Green Algae (phylum Chlorophyta)
Multicellular Green Algae
Ulva – sea lettuce

5. Multicellular Plant-Like Protists
Red Algae (phylum Rhodophyta)
Contain chlorophyll a and phycobilins
Found in marine water from polar region to tropical waters
Grow anywhere from ocean’s surface to 260 meters

6. Fungus-like Protists
Slime Molds – play a key role in recycling organic material
Cellular Slime Molds (phylum Acrasiomycota)
Usually free-living cells
Lack of food: cells come together as a colony to reproduce sexually
Acellular Slime Molds (phylum Myoxmycota)
Lack of food: cells fuse to produce structures with many nuclei (plasmodium) and then reproduce sexually

7. Fungus-like Protists Water molds (phylum Oomycota)
Feed on dead or decaying organic matter in water and are plant parasites on land
Produce thin filaments called hypha, but no cell walls are present
