Protist General Biology Mr. Cobb
General Characteristics • Eukaryotic • Microscopic • General “catchall” kingdom • Like the “junk” draw in the kitchen • Described as: • Animal-like • Plant-like • Fungus-like
3 Types of Protists • Protozoan – animal-like • Algae – Plant-like • Fungus - like
Protozoan characteristics • Microscopic and unicellular • Most are aquatic • Classified by locomotion (movement)
Sarcodina Phylum Amoeba: no body shape Move slowly with a pseudopodium Responds to stimuli Surrounds its food and engulfs it
Cilates • Paramecium: • Move by cilia • Covered with cilia (little hairs for movement) • Oral groove to take in food
Paramecium Structure • hparamechighthumb.jpg
Sporozoans • Do not move • Parasitic • Plasmodium – causes malaria in the Anopheles mosquito Anopheles Mosquito Ruptured Red blood cells Life cycle
Flagellates • Propel by one or more flagella • Known as Zooflagellates • Causing African Sleeping Sickness Tsetse Fly Trypansome
Algae • Unicellular or colonial • Found in all water • Primary food source for zooplankton • 70% of photosynthesis on the planet
Algae Types • Euglena (algae with flagella) • Green Algae (stuff on the boat and pool) • Golden Algae • Diatoms (contain silica) (geometric shapes) • Brown Algae • Red Algae • Dinoflagelletes ( contain 2 flagellas and cause red tides)
Diatoms Purple Diatoms
Euglena • Algae with a flagella
Fungus-like Protist • Hetertrophic like Fungus but: • Cellulose cell wall • Motile • Two types: • Watermolds • Slimemolds
Watermolds • The “stuff” growing on dead fish. • Caused Potato blight
