Plasmodial slime molds are single-celled organisms which are not closely related to fungi or cellular slime molds, even though they appear similar to cellular slime molds in appearance.[1] Not only that, but they primarily store energy as glycogen like fungi and cellular slime molds.[2] Plasmodial slime molds can not live in an aquatic environment and are entirely terrestrial.[3] Plasmodial slime molds get their name from their lack of cell walls or “naked” cells.[4] These heterotrophic organisms use this to their advantage, because they are able to engulf and digest bacteria, yeast, fungal spores, and decaying matter.[5]

Reproduction

The organism can undergo asexual reproduction, and also has a sporic meiosis life cycle, or alternation of generations.[6] The cycle differs from many other organisms in that it has two haploid forms, a diploid form, and a multinucleate plasmodium.[7] The multinucleate plasmodium can form a dormant encysted stage, the sclerotium, or form sporangia, which produce haploid spores.[8] These spores may also be dormant, or germinated into one of two forms, amoebas or flagellated gametes.[9] Two gametes may then fuse to form a diploid zygote, which grows into a multinucleate plasmodium.[10]
