BIO 1002 EXAM 2
| Question | Answer |
|---|---|
| Fungi usually obtain food by: | digesting it externally and then absorbing it |
| As a group, fungi are _____. | decomposers (Fungi obtain nutrients from nonliving organic matter.) |
| Fungi release digestive enzymes into their _____. | surroundings (Fungi then absorb the digested nutrients.) |
| Basidia produce spores by a process known as _____. | meiosis (Basidia produce spores by meiosis.) |
| Chytrids are the fungal species best adapted to colonizing dry environments. True or False? | False |
| Fairy rings are produced by basidiomycetes. True or False? | True |
| Which fungal group produces swimming, flagellated spores? | chytrids |
| ________ form beneficial symbiotic relationships with plant roots. | Glomeromycetes |
| Which fungal phylum usually carries on sexual reproduction? | basidiomycetes |
| The specialized reproductive structures of club fungi are called: | basidia. |
| How does a plant benefit from an association between the plant's roots and a fungus? | The fungus processes soil nutrients and minerals and passes those from soil to the root cells of the plant. (Both partners benefit from this association; the plant feeds the fungus energy-rich sugar molecules.) |
| A more or less circular ring of mushrooms appears in your yard, apparently overnight. The circle is several yards in diameter. The mushrooms appear to be producing spores. What is the most likely explanation for this circle of mushrooms? | The mushrooms are all part of the same organism, with mycelia radiating out from the location of a germinated spore. |
| Mycorrhizae are plant parasites. True or False? | False |
| Which fungus species is responsible for the destruction of American elm trees? | ascomycetes |
| Fungal feeding network that is usually unseen. | Mycelium |
| Mutualistic partnership involving single cell photosynthetic organisms. | Lichen |
| Whimsical name for a ring of reproductive structures of club fungi. | Fairy Ring |
| Name of the sac that contains the spores of Sac Fungi. | Ascus |
| Reproductive cells formed from basidia by the process of meiosis. | Basidiospores |
| Partitioning structures present in some species of fungi. | Septa |
| Material used to build the cell wall of a fungus. | Chitin |
| Thick walled structure the forms from the fusion of two different mating types of zygote fungi. | Zygospore |
| Division of fungi that lack septa and reproduce mainly by an asexual cycle | Zygote Fungi |
| Division of fungi that have septa and reproduce using ascus. | Sac Fungi |
| Division of fungi that the common mushroom belongs in. | Club Fungi |
| An organism in the aquatic fungal division. | Chytrid |
| General term for structures that make spore. | Sporangia |
| Fungal division that is part of a beneficial symbiotic partnership with plants. | Mycorrhizae Fungi |
| Specific spore producing structures of club fungi. | Basidia |
| General term for an organism that derives nutrients from decaying material. | Saprobe |
| Threadlike component of mycelium. | Hypha |
| General structure used by fungi for reproduction. | Spore |
