Are slime molds multicellular or unicellular?
Slime molds are mostly considered multicellular. They begin as unicellular organisms, but then transform into multicellular organisms during the different phases of its life cycle.
Basically, slime molds are unicellular protists that form the multicellular, visible slime mold when under stress or seeking to divide.
Two broad groups of slime molds are recognized. The individual cells of cellular slime molds remain distinct– separated by cell membranes– during every phase of the mold’s life cycle. Slime molds that pass through a stage in which their cells fuse to form large cells with many nuclei are called acellular slime molds.
