Definition
-580 species -> algae that lost their chloroplasts??
-have “hyphae” that make spores like fungi
-cellulose or chitin cell walls & flagellated swimming spores like algae
-unicellular(some), others w/ many hyphae(fine, branching filaments)
-not fungi: diploid stage dominates in oomycotes and they have biflagellated cells
-decomposers or plant pathogens -> absorb predigested nutrients -> saphrophytes or parasite in moist environment |
