EUKARYA BACTERIA ARCHAEA Protists Plants Fungi Animals Protists more distinct from each other than plants, animals, and fungi are
Protists Mainly single celled eukaryotes (some are colonial, others multicellular) species in the genus Volvocales range from unicellular to colonial to multicellular.
Protists Often have a very complicated internal structure
Protists Forms –fungus-like –plant-like –animal-like –probably little to do with their evolutionary history
Fungus-like Protists Water molds and slime molds
Animal-like Protists classified according to how they move: –amoeba-like –ciliated – flagellated
Protists and Human Health and Welfare Many protists are responsible for human diseases, such as malaria.
–Giardia - causes diarrhea – Trypanosoma - causes sleeping sicknes
most single-celled, but some multicellular have chloroplasts include –Diatoms –Dinoflagellates (red tides) –Algae – green, red, brown Plant-like Protists
Figure 28.17x Diatom shell
Figure 28.17 Diatoms: Diatom diversity (left), Pinnularia (left)
Dinoflagellates Importance: parasites on fish cause “red tides” contain toxins cause mass mortalities of aquatic organisms
Algae Classified as: –green (mostly freshwater) –red (marine) –brown (marine “kelps”)
Green Algae The green algae are the ancestors of plants.
Ulva – “sea lettuce”
Codium © D. Stengel
Brown Algae “kelp”
Why are algae important? Production of Oxygen Production of biomass: -the leading primary producers in oceans and basis for marine and freshwater food chains
Grazing protists Photosynthetic protists Protists and Human Health and Welfare
Also … algae serves as human food –Annual value is about US$6 billion
CALIFORNIA California kelp forests considered most diverse in world
Kelp (Brown Algae) 1000 species, almost all marine most common in cold, temperate seas
Giant Kelps - largest of all algae Kelp Forests –one kelp can grow 25-30 m in one season –can reach 45 m long –among most productive of all plant communities
Parts of a kelp –Gas-filled pneumatocysts –Rootlike holdfast to attach to substrate –Long hollow stem or stipe –Leaflike blades FUNCTION AND FORM
Kelp forests - Where do they occur? Cold, temperate water
The ecological role of kelp
Dampen wave action Reduce coastal erosion Support populations of fish and invertebrates Habitat for many species
Animals of the kelp forest
Sea urchins graze on kelp
Sea otters control urchin populations by eating them
Now in trouble - not so diverse
Kelp Harvesting Old methods –led to reduction of many small marine creatures including abalone –now restricted
Kelp Harvesting Now Currently >100 tons of kelp are removed off the California coast alone --- down from 170,000
3 large groupings of Protists -protozoans (animal like) -slime molds and water molds (fungi like) -algae (plant like) Members of a Kingdom that is under.

Diversity of Algae There are millions of algal species, but we’ll focus in these five groups: Diatoms Dinoflagellates Red Algae Kelps or Brown Algae Green.
Protists KEY CONCEPT Kingdom Protista is the most diverse of all the kingdoms.
Protists. Protist Characteristics An extremely diverse group Eukaryotes Mostly unicellular some colonial some multicellular Some heterotrophic, some autotrophic,
Kingdom Protista Known as the “catch all” kingdom.
Protists Kingdom Protista is the most diverse of all the kingdoms. Are protists eukaryotes or prokaryotes?
What are protists? Very diverse group of organisms containing over 200,000 species Most are unicellular.
KINGDOM PROTISTA Kingdom Protista * all eukaryotes * mostly unicellular Protozoans “animal-like” Algae “plant-like” Fungus-like Protists.

KINGDOM: PROTISTA POINT > Identify 3 major groups of protists POINT > Describe 4 types of “animal-like” protists POINT > Describe 6 types of “plant-like”
Introduction to Kingdom Protista Domain Eukarya, Kingdom Protista –Any eukaryote that is not classified as a fungus, plant or animal Three major groups:
Protists. 1.A protist is any organism that is not a plant, an animal, a fungus, or a prokaryote.
PROTISTS. KINGDOM PHYLUM GENUS FAMILY CLASS ORDER SPECIES DOMAIN.
The Protists Eukaryotes. Most unicellular. Most aerobic. Moist environments Can be photoheterotrophs or photoautotrophs, chemoheterotrophs or mixotrophs.
