Protista Kingdom

What is A Protista? A eukaryotic, unicellular organism that lives in wet environments 3 Types: Plant-like protista Animal-like protista Fungi-like protista

Animal-Like Protista Heterotrophic (Consumers) Move

Protista Movement Pseudopods = “false foot” Pushes out membrane to move The Ameba moves like a blob

Protista Movement Cilia = “hair-like” projections Move like a wave to sense environment & gather food Example: Paramecium

Protista Movement Flagella = A “whip-like” structure that helps it move

Fungus-like Protista Heterotrophs Have cell wall Use spores to reproduce Examples Water molds, Downy mildews, and Slime molds!

Plant-like Protista Autotrophs: use photosynthesis Important to the food chain! Examples: Algae, Diatoms, Dinoflagellates Video Review

Algal Blooms Eutrophication: If too many nutrients enter the water it causes a big increase in algae The algae then take all the oxygen Harmful to other organisms

Fungi Kingdom

Characteristics Eukaryotes Reproduce using spores: tiny cells that can grow into a new organism Heterotrophs: absorb or eat food Live in moist environments

Cell Structure Hyphae: threadlike tubes Hyphae can also produce chemicals to break down food

Reproduction spores Asexual: budding & spores Sexual: Two hyphae join together to exchange genetic info spores

Examples of Fungi Mushrooms, molds, mildews, & yeast

Roles of Fungi Decomposers: break down dead organisms Food: bakers yeast & mushrooms Disease: cause disease in plants and animals Athletes foot Antibiotics: penicillin
