Reviewing the life cycle and then checking it against their predictions, helped my students better explain the life cycle phenomena to each other. They reproduce both sexually and asexually; the asexual spores are called diploid zoospores. Life Cycles / Book \ NDBUPPZFIN Life Cycles By Marks, Marilyn Creative Teaching Pr, 1999. The life cycle of all living organisms ultimately is based on their manner of reproduction. Chytridiomycota, a phylum of fungi (kingdom Fungi) distinguished by having zoospores (motile cells) with a single, posterior, whiplash structure (flagellum). (1982). Zoospores are attracted to the host cell by specific signals. Chytridiomycota, a phylum of fungi (kingdom Fungi) distinguished by having zoospores (motile cells) with a single, posterior, whiplash structure (flagellum). The life cycle of a basidiomycete usually includes a long-lived dikaryotic mycelium In response to environmental stimuli, the mycelium reproduces sexually by producing elaborate fruiting bodies call basidiocarps Mushrooms are examples of basidiocarps The numerous basidia in a basidiocarp are sources of sexual spores called basidiospores endobj This generalized diagram (Fig. zoospore of the Chytridiomycete Physoderma gerhardti .

LLMB3_1 PML-2011m Chytridiomycota sp. Ascospores of most ascomycetes contain one or more haploid nuclei , and therefore most (but by no means all) ascomycetes have a haploid vegetative mycelium . The Phylum Chytridiomycota (chytrids) is one of the five true phyla of fungi. The kingdom Fungi contains five major phyla, which were established according to their mode of sexual reproduction or use of molecular data. The chytrid Batrachochytrium dendrobatidis is seen in these light micrographs as transparent spheres growing on (a) a freshwater arthropod and (b) algae. The phylum Chytridiomycota contains one class, the Chytridiomycetes, and is composed of five different orders. Peronsporales: Only secondary zoospore is produced.
