Episode notes
Slime Mold Is A Single-Cell Protist
- Slime molds are protists, not animals or fungi, and were reclassified from fungi to protists.
- Some plasmodial slime molds form single giant cells without cell walls containing millions of nuclei.
Giant Blobs That Are One Cell
- Some plasmodial slime molds can reach pizza-size while remaining one giant cell with many nuclei.
- They lack cell walls so the cytoplasm flows as a single organism rather than distinct cells.
Cells That Team Up Like A Flock
- Cellular slime molds are single-celled but aggregate into a pseudoplasmodium under stress.
- They retain cell walls when aggregated and can disperse again when food is abundant.
