Document Summary
Introduction: fungi are polyphyletic and belong to 2 kingdoms: kingdom. The arrangement only benefits the parasite: 3) mutualistic: is the way two organisms of different species exist in a relationship in which each individual benefits. The mycelium: the mycelium is the fungal body , and is composed of many hair-like hyphae, hyphae are composed of cell wall with chitin and cellulose, the thickness and other features of hyphae can vary, depending on the species. Pseudofungi phylum oomycota: one of the lower fungi, evidence suggests they are part of chromista clade, or. Supergroup chromaveolata, in kingdom protoctista: they are oogamous, but can also reproduce asexually, asexually via zoosporangia and heterokontous zoospores, 2 orders, 1 aquatic; water mold, 1 terrestrial; downy mildews converged with powdery mildews. Reproduction: 2) eucarpic: outside of host, anisogamous, life cycle of a chytrid rhizophidium. Phylum dikaryomycota: includes true fungi with dikaryon (1n+1n) phase, hyphae are thin and resistant to drying out, includes 2 subphylum, 1) subphylum ascomycotina.
