Fungus – Like Protists Chapter 19 p. 540

Fungus-like Protists p p These organisms lack chlorophyll and absorb food through cell walls Include cellular slime molds, and water molds Slime mold Water Mold

Kingdom Fungi vs. Kingdom Protista p p Fungi have cell walls made of chitin Fungus-like protists contain centrioles while true fungi lack centrioles

Phylum Acrasiomycota Cellular Slime Molds p Begin life cycle as ameba-like cells p When a cell begins to run out of moisture or food, it sends out chemical signals that attract other cells of the same species p n n Thousands of cells will aggregate into a large slug-like mass This mass migrates for several centimeters and then stops to form a fruiting body releases spores

FRUITING BODY Contain haploid spores!

Phylum Myxomycota p p Acellular Slime Molds Begin life cycles as amebalike cells that grow into large masses n The Mass is actually a single cell with thousands of nuclei

Slime Mold on the move p Slime Mold movement p

Acellular Slime Mold cont. They stream across leaves and twigs eating bacteria and other organic matter p Eventually they form fruiting bodies spores p When they make contact with soil, they germinate to produce flagellated cells p n These cells fuse to produce diploid (2 n) amebalike cells

Water Molds Phylum Oomycota p They thrive on dead or decaying matter p They have cell walls made of cellulose and produce spores that swim rapidly!! p n p These characteristics are ones that fungi do not share makes them a protist! Most live in water but some live on land n Land water molds include parasites of crops like grapes, avocados and potatoes

Water Mold

Potato Mold and Grape Mold
