Introduction

Physarum polycephalum is a species of acellular slime molds, or myxomycetes. Despite having a similar name to fungi, these organisms are protists. They are most commonly found in soil, moist vegetation, and the forest floor where it is cool, damp, and dark, where they contribute to the decomposition of dead vegetation. P. polycephalum has a very diverse life cycle, as they can range from being a microscopic single-celled amoeba, a multinucleated cell, or plasmodium, that can span several feet, morphing into a hardened mass known as a sclerotium, or forming small, delicate fruiting bodies that produce haploid spores.

Section 1 Genetics

Include some current research, with at least one image.

Sample citations: [1] [2]

A citation code consists of a hyperlinked reference within "ref" begin and end codes.

[3]

Section 2 Microbiome

Include some current research, with a second image.

Conclusion

Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
