What do all fungi have in common? absorption of nutrients The hydrolytic digestion of _____ should produce the monomer, an aminated molecule of -glucose? Insect exoskeleton and fungal cell walls If all saprobic fungi in an environment were to suddenly die, which group of organisms should benefit as a whole? prokaryotes When a mycelium infiltrates an unexploited source of dead organic matter, what are most likely to appear within the food source soon thereafter? c. exoenzymes What is NOT a characteristic of hyphate fungi? they may be saprobes, parasites, or mutualistic symbionts What is the primary role of a mushroom's underground mycelium? Absorbing nutrients What do fungi and arthropods have in common? The protective coats of both groups are made of chitin. In septate fungi, what structures allow cytoplasmic streaming to distribute needed nutrients, synthesized compounds, and organelles throughout the hyphae? pores in cross-walls What best accounts for the extremely fast growth of a fungal mycelium? A rapid distribution of synthesized proteins by cytoplasmic streaming The vegetative bodies of MOST fungi are..? composed of hyphae, referred to as a mycelium, usually underground Which of the following cannot be assigned to any kind of morphology or to any fungal taxon? Yeast In fungi, karyogamy does not inmediately follow plasmogamy, which.. Results in heterokaryotic cells What is a fungal process that has opposite effect in chromosome number than effect of meiosis? karyogamy What is the ploidy of a single mature Neurospera ascospore? Haploid Each of the eight ascospores present at the end of mitosis has the same chromosome number and DNA content (ng) as each of the four cells at the end of meiosis. What must have occurred between the round of meiosis and the round of mitosis? S phase Cytokinesis is to nuclear division as ___ is to karyogamy. plasmogamy Which is true about deuteromycetes? No sexual stage Which of the following is characterized by the lack if an observed sexual phase in its members' life cycle? Deuteromycota A biologist is trying to classify a new organism on the basis of the following characteristics: fungus-like in appearance, reproduces by conidia, has no apparent sexual phase, and parasitizes woody plants. If asked for advice, to which group would you assign this new species? Deuteromycota Which is a component of both chytrid zoospore and motile animal cell? 9+2 pattern of microtubules in flagella Considered a the taxonomic level of the kingdom, which of the following constitute a monophyletic clade? Chytrids and fungi What combination of environmental and morphological change is similar in the evolution of both fungi and plants? Colonization of land and loss of flagellated cells What is not shared by both chytrids and other fungi? Flagellated zoospores This phylum contains organisms that most closely resemble the common ancestor of fungi and animals: Chytridiomycota This phylum formerly included the members of the new phylum Glomeromycota: Zygomycota Members of this phylum produce two kinds of haploid spores, one kind being asexually produced conidia: Ascomycota This phylum contains the mushrooms, shelf fungi, and puffballs: Basidiomycota Member of this phylum form arbuscular mychorrizae Glomeromycota You have been given the assignment of locating living members of the phylum glomeromycota, where can you find it? Roots of vascular plants What are the sporangia of the bread molds?
