Acrasiomycetes -

: Because they never fuse their cell membranes, they are often used by scientists to study how single-celled life evolved the ability to cooperate and build multicellular organisms.

If you are studying Acrasiomycetes, these are the core biological characteristics that define them: acrasiomycetes

: They live independently in soil or decaying plant matter eating bacteria. They only come together into a visible structure as a survival mechanism to cast off spores. : Because they never fuse their cell membranes,

The class does not form a "solid piece" or a single fused mass at any point in its life cycle. Instead, these organisms are defined as cellular slime molds , meaning they maintain their individual cell membranes at all times. The class does not form a "solid piece"

: The individual amoebas move by abruptly extending lobe-like "false feet" to pull themselves forward.
