Question: why myxomycetes are called slime molds?
Answer: This class is commonly referred to as the acellular slime molds because the plasmodium (Figs. 7-8) stage of the lifecycle is not composed of many cells. Instead it is essentially a single, multinucleate cell. As in the myxamoebae stage, the plasmodium is also an assimilative stage that consumes food by phagocytosis.
