Which of the following do all fungi have in common? a. meiosis in basidia d. absorption of nutrients b. coenocytic hyphae e. symbioses with algae c. sexual life cycle 2. If all saprobic fungi in an environment were to suddenly die, which group of organisms should benefit as a whole? a. plants d. animals b. protists e. mutualistic fungi c. prokaryotes 3. Which of the following is not a characteristic of hyphate fungi (fungi featuring hyphae)? a. They acquire their nutrients by absorption. b. Their body plan is a netlike mass of filaments called a mycelium. c. Their cell walls consist mainly of cellulose microfibrils. d. They may be saprobes, parasites, or mutualistic symbionts. e. The nuclei of the mycelia are typically haploid. 4. The functional significance of porous septa in certain fungal hyphae is most similar to that represented by the ____ of certain animal cells, and by the ____ of certain plant cells. a. desmosomes; tonoplasts d. centrioles; plastids b. gap junctions; plasmodesmata e. flagella; central vacuoles c. tight junctions; plastids 5. What is the primary role of a mushroom's underground mycelium? a. absorbing nutrients d. asexual reproduction b. anchoring e. protection c. sexual reproduction 6. What do fungi and arthropods have in common? a. Both groups are commonly coenocytic. b. The haploid state is dominant in both groups. c. Both groups are predominantly saprobic in nutrition. d. The protective coats of both groups are made of chitin. e. Both groups have cell walls. 7. In septate fungi, what structures allow cytoplasmic streaming to distribute needed nutrients, synthesized compounds, and organelles throughout the hyphae? a. chitinous layers in cell walls b. pores in septal walls c. complex microtubular cytoskeletons d. two nuclei e. tight junctions that form in septal walls between cells 8. The vegetative (nutritionally active) bodies of most fungi are a. composed of hyphae. d. A and B only b. referred to as a mycelium. e. A, B, and C c. usually underground. 9. Consider two hyphae having equal dimensions: one from a septate species and the other from a coenocytic species. Compared with the septate species, the coenocytic species should have a. fewer nuclei. d. less cytoplasm.
