$e .$ possess flagella.

Key Concepts

Pseudoplasmodium

A pseudoplasmodium is an aggregative structure formed by the coming together of individual amoeboid cells, primarily observed in cellular slime molds. This differs from the plasmodial form found in plasmodial slime molds, which involves a continuous, multinucleate mass rather than an aggregation of separate cells.

Flagella

Flagella are whip-like structures used for locomotion in some unicellular organisms. In the context of slime molds, particularly the plasmodial type, flagella are not typically present, as movement is powered by cytoplasmic streaming and the extension of pseudopodia.

Myxamoeba

Myxamoebae are individual, amoeboid cells typically associated with cellular slime molds. They represent a different stage in the life cycle compared to the syncytial plasmodium of plasmodial slime molds, where cells aggregate rather than forming a continuous multinucleate mass.

Coenocyte

A coenocyte is a cell that contains multiple nuclei that share a common cytoplasm, with no dividing cell membranes between them. In plasmodial slime molds, the plasmodium is a coenocytic structure that allows efficient distribution of nutrients and can rapidly respond to environmental changes.

Plasmodial Slime Molds

Plasmodial slime molds are eukaryotic organisms that undergo a unique life cycle characterized by a large, multinucleate cell known as a plasmodium. This stage is highly motile and feeds by phagocytosis, and it eventually differentiates to form structures for reproduction.

Fruiting Bodies

Fruiting bodies are specialized reproductive structures produced by many organisms to facilitate the production and dispersal of spores. In the life cycle of plasmodial slime molds, the plasmodium eventually forms fruiting bodies, which then generate spores for propagation under favorable conditions.
