1. Fungus – Like Protists
Chapter 19 p. 540

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

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

4. Phylum Acrasiomycota Cellular Slime Molds
Begin life cycle as ameba-like cells
When a cell begins to run out of moisture or food, it sends out chemical signals that attract other cells of the same species
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

5. Contain haploid spores!
FRUITING BODY
Contain haploid spores!

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

7. Slime Mold on the move
Slime Mold movement

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

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