Habitat. Slime molds live in somewhat variable habitats all over the world. Generally slime molds live in damp areas of vegetation. They live under rotting logs and damp leaves. Some of the other habitats that slime molds will inhabit include water such as tropical fish tanks.
Cellular Slime Molds. As mentioned above, the vegetative phase of the cellular slime molds is an ameboid cell. Depending on environmental conditions, these cells will enter either the sexual or the asexual reproductive phase. For sexual reproduction, two cells of opposite mating types fuse to create a diploid cell.
