What is the difference between molds and slime molds?

a) Slime molds are aquatic molds

b) Molds are fungi, while slime molds are not

c) There is no difference

b). Molds are multicellular, filamentous fungi, while slime molds belong to a more primitive group of organisms called the Protista, which form unicellular or colonial forms such as amoebas and primitive algae.
