20.5 Funguslike Protists

Page 2: Biology 20.5

Cellular Slime Mold• Slime mold whose individual cells remain

separated during every phase of the mold’s life cycle.

Page 3: Biology 20.5

Acellular Slime Mold • Slime mold that passes through a stage in

which its cells fuse to form large cells with many nuclei.

Page 4: Biology 20.5

Fruiting Body

• Slender reproductive structure that produces spores and is found in some funguslike protists; reproductive structure of fungus that develops from a mycelium.

Page 5: Biology 20.5

Plasmodium• Structure with many nuclei formed by

acellular slime molds.

Page 6: Biology 20.5

Hypha• Tiny filament that makes up a multicellular

fungus or a water mold.

Page 7: Biology 20.5

Zoosporangium • Spore case.

Page 8: Biology 20.5

Antheridium• Male reproductive structure in some algae

and plants.

Page 9: Biology 20.5

Oogonium • Specialized structure formed by hyphae that

produces female nuclei.

Key Concept

• Like fungi, the funguslike protists are heterotrophs that absorb nutrients from dead or decaying organic matter. But unlike most true fungi, funguslike protists have centrioles. They also lack the chitin cell walls of true fungi.

Key Concept

• Oomycetes thrive on dead or decaying organic matter in water and some are plant parasites on land.
