Kingdom Protista

Introduction Does not fit into kingdom fungi, animalia, or plantae Live in water Most are unicellular and some are multicellular Features may represent convergent evolution Three Types Plant-like (algae like) Animal like (protozoa) Fungus like

Animal-like Heterotrophs Consume either living or dead organic material Method of Movement: Pseudopods (amoeba) Flagella (euglena) Cilia (paramecium)

Plant-like Most are autotrophs Obtain energy from photosynthesis Has chloroplasts Algae are multicellular Euglena – autotroph and heterotroph

Fungus-like Resemble fungus do to spore-bearing bodies Ex. slime molds  spores germinate into cells

Kingdom Fungi

Introduction Fungi grow as filaments (hyphae) Mycelium = mass of hyphae Septa = cross walls dividing filament into compartments containing single nucleus Cell walls consist of chitin

Introduction Fungi are parasites or decomposers Absorb the breakdown products from the action of digestive enzymes secreted Some form mutualistic arrangements Mycorrhizae = between fungus and plants Grows on roots of plants facilitating the movement of water and minerals into the plant in exchange for sugars Lichens = between fungus and algae Alga provide sugars and nitrogen compounds and fungus provides water and protection from environment
