Which characteristic of fungi? Most are single-celled, live in moist areas. All of the above are characteristics of fungi. Sporophyte Decomposer Why is the relationship between mycorrhizal fungi and their host plants considered mutualistic? They live in close physical association. Both species benefit from the association. The host plant cannot live without the mycorrhizae. The mycorrhizae cannot live without the host plant. What do seeds contain? Male gametophyte and nutritive tissue. Female gametophyte and nutritive tissue. Embryo and nutritive tissue. Mature sporophyte and nutritive tissue. Haploid unicellular spores are produced via: mitosis fertilization: conjugation: 10. How can nonvascular plants survive on land without true roots? They are small enough to allow minerals to diffuse throughout their bodies. They live in moist habitats. They have a thick cuticle to prevent water loss. Both A and B. The hyphae of arbuscular mycorrhizal fungi (AMF) form bush balloon-like structures after making contact with the plasma membrane of the root cells. Why? A. They anchor the fungus inside the root; so the association is more permanent. They increase the surface area available for the transfer of nutrients. They produce toxins that protect the plant against herbivores. They break down cellulose and lignin in the plant cell wall. The sporophyte-dominated life cycle originated in: Green algae. Plants. Gymnosperms. Angiosperms. Non-vascular plants. Seedless vascular plants. 13. The appearance of cuticle and stomata are correlated with what event in the evolution of plants? The first erect growth forms. The first woody tissues. The growth of roots. The evolution of the first water-conducting tissues.

47) What is the major distinguishing characteristic of fungi? A) acquiring nutrition through ingestion B) decomposing dead organisms C) prokaryotic cells D) absorbing nutrients E) sedentary lifestyle 48) Why is it more difficult to treat fungal infections than bacterial infections in humans? A) Fungal and animal cells and proteins are similar. Thus, drugs that disrupt fungal cell or protein function may also disrupt human cell or protein function. B) Fungi are able to mutate more quickly than bacteria, so they quickly develop resistance to antifungal drugs. C) Most fungi are multicellular and thus the drugs required to treat a fungal infection must be able to kill several types of cells; bacteria, on the other hand, are unicellular and thus simpler to kill. D) Fungi are larger organisms than bacteria and thus require stronger drugs to stop an infection. 49) In septate fungi, what structures allow cytoplasmic streaming to distribute needed nutrients, synthesized compounds, and organelles throughout the hyphae? A) pores in septa B) complex microtubular cytoskeletons C) two nuclei D) tight junctions that form in cross-walls between cells E) multiple chitinous layers in cross-walls

What is the nutritive of most fungi? To which kingdom do fungi belong? What is the name given to organisms which feed on dead or decaying organic matter? Are any fungi parasites? What is the basic reproductive structure in fungi? Which hypha function similar to the "runners" of strawberries? What are the rootlike structures of fungi? What kind of spores are produced by the Phylum Ascomycetes? What kind of spores are produced by the Phylum Basidiomycotes? Since fungi cannot make their own food, they are and their mode of nutrition is by The basic filaments of fungal growth are called , and a mass of these filaments is called a When you leave the top off of a jar of food, or leave bread uncovered, it is likely to become "moldy." Where might the mold have come from? Many people are "allergic to fungi." They cough and sneeze and sniffle. Couldn't they avoid their suffering if they just would not eat mushrooms? Explain.
