Explore the intriguing life cycle of Plasmodial Slime Molds, belonging to the Myxomycota phylum. These multinucleate organisms exhibit unique locomotion through cytoplasmic streaming and have flagellated or amoeboid reproductive cells. During the feeding stage, the plasmodium ingests bacteria, yeasts, spores, and decaying organic matter. Witness the formation of sporangia, production of haploid spores through meiosis, and the emergence of haploid reproductive cells. Observe how these cells, either biflagellate or amoeboid, work as gametes to form a zygote. Delve into the world of Plasmodial Slime Molds as they undergo reproductive processes involving mitosis and cytoplasmic activities.

Plasmodial Slime Molds! by Jessica Ackerman
Phylum: Myxomycota Multinucleate plasmodium Locomotion Cytoplasmic streaming Flagellated or amoeboid reproductive cells General Information
Feeding • Feeding stage: plasmodium • Multinucleate mass of cytoplasm • Slimy in appearance • Streams over decaying logs and leaf litter • Ingests bacteria, yeasts, spores, and decaying organic matter
Plasmodium crawls to an exposed surface Initiates reproduction Sporangia forms (stalked structure) Meiosis produces haploid spores Reproduction
Spores germinate Haploid reproductive cell emerges May be biflagellate or amoeboid Work as gametes—two fuse to form a zygote Diploid nucleus divides by mitosis—cytoplasm does not divide Reproduction
