BIOL 1030 Review 1
BIOL 1030 Review
| Question | Answer |
|---|---|
| Which group contains the organism, Trypanosoma, that causes African sleeping sickness? | Discicristata |
| You are doing a study of the DNA sequences of members of Kingdom Fungi to try to resolve questions about the phylogeny of the group. Which of the following would best serve as an outgroup for your study? | a fish |
| The definition of species as a single line of descent that maintains its distinctive identity from other lineages is called the _______ species concept. | evolutionary |
| Members of this phylum have double shells of silica that fit together like a box and a lid. “grass of the sea”. Fossils deposits of these organisms are mined for use in pest control, reflective paints, and filters. | Bacillariophyta |
| Sexual reproduction in club fungi, which have only dikaryotic hyphae in their fruiting bodies, involves production of spores in structures called | basidia. |
| When using a cladistic approach to systematics, which of the following is considered most important for classification? | shared derived characters |
| Which of these kingdoms is a paraphyletic group at best? | Protista |
| Members of this phylum form endomycorrhizae, also called arbuscular mycorrhizae, an important mutualism for plants. | Glomeromycota |
| Which of the following is true in the fern life cycle? | gametophytes are free-living and photosynthetic, but are replaced by a dominant sporophyte generation |
| Members of this plant phylum have true leaves, but those leaves have only a single vein of vascular tissue and are called microphylls, in contrast to the megaphylls that are found in most other vascular plants. | Lycophyta |
| Which process hinders clarification of the deepest branchings in a phylogenetic tree that depicts the origins of the three domains? | horizontal gene transfer |
| Although it does not belong to the group itself, A member of phylum Myxomycota is most closely related to members of which of the following? | Opisthokonta |
| Which of the following pairs of protist groups and their characteristics is mismatched? | Gymnamoeba : parasitic amoebas |
| Lichens are symbiotic (and usually mutualistic) associations. One member of the pair is always a fungus. The other member of the pair is often part of which of the following groups? | Chlorophyta |
| If a fern gametophyte is a hermaphrodite (that is, has both male and female gametangia on the same plant), then it | belongs to a species that is homosporous. |
| The _________________ is the sexual structure that produces sperm in plants. | antheridium |
| Which of the following groups includes organisms that form zooanthellae in other organisms such as corals, but also has predatory members that can create toxins that they use to kill marine life, including organisms as large as fish? | Dinoflagellata |
| For mycelia described as being dikaryotic, which process has already occurred, and which process has not yet occurred? | plasmogamy, karyogamy |
| Zygosporangia are to zygomycetes as asci are to | sac fungi. |
| These are small passages through the cuticle in plants that can open and close, allowing for some control of water loss by evaporation. In plants that have them, they are the main route for uptake of carbon dioxide. | stomata |
| Related classes are grouped into a/an _________ as the next higher taxonomic level. | phylum |
| Which of the following Eukarya “supergroups” includes, among other groups, Bacillariophyta and Phaeophyta? | Stramenopila |
| Which kind of DNA should provide the best molecular clock for gauging the evolutionary relatedness of several species whose common ancestor became extinct billions of years ago? | that coding for ribosomal RNA |
| A biologist discovers an alga that is marine, multicellular, and lives at a depth reached only by blue light. This alga probably belongs to which group? | Rhodophyta |
| The green parts of a liverwort belong to the _______________________ generation. | haploid gametophyte |
| non-vascular plant with a dominant gametophyte that grows prostrate, sporophytes dependent on that gametophyte growing out of some stalked structures, and gemmae cups for asexual reproduction. This plant is best classified as a member of which groups? | Hepatophyta |
| All living members of this seedless vascular plant phylum are classified in the same genus, Equisetum. Members of this phylum are characterized by having jointed, photosynthetic stems with scale-like leaves at the stem nodes; | Arthrophyta |
| Members of this group spend most of their life as free-living, individual cells, but with the proper trigger will aggregate into a multicellular form that migrates toward light and then becomes a sessile fruiting body called a sorocarp. | Acrasiomycota |
| The following are all true about the life cycle of mosses except | the growing embryo gives rise to the gametophyte. |
| Which of the following groupings represents a clade | Ascomycota, Basidiomycota, and Glomeromycota |
| Which of these is a fungal structure that is usually associated with asexual reproduction? | conidiophore |
| Based on the phylogeny that we are using in this course, which of the following groups forms a basal paraphyletic assemblage within Kingdom Fungi | Chytridiomycota |
| You are given an organism to identify. It has a fruiting body that contains many structures with eight haploid spores lined up in a row. What group does this fungus belong to? | Ascomycota |
| Based on the phylogeny that we are using in this course, which of the following groups or groupings is a sister group to Basidiomycota? | Ascomycota |
| The members of this phylum are all multicellular, and often large, including some important marine producers called kelps (example: Sargassum). Their chloroplasts have chlorophylls a and c, | Phaeophyta |
| new unicellular organism that possesses multiple flagella, a pronounced feeding groove, and two small, but equal-sized, nuclei. The organism has reduced mitochondria (mitosomes), no chloroplasts, anaerobic. which clade does this organism belong? | Excavata |
| The best classification system is that which most closely | reflects evolutionary history. |
| Tests and thread-like pseudopodia that can perform phagocytosis are generally characteristic of which group? | Rhizaria |
| this phylum of seedless vascular plants have no true roots or leaves; instead, they are essentially forking green stems. The six living species of this phylum are the living plants that look most like the oldest vascular plant fossils, Cooksonia. | Psilophyta |
| If Archaeplastida is eventually designated a kingdom that includes the groups taught in this course as being part of it (Rhodophyta, Chlorophyta, and Plantae), then what will be true of this new kingdom? | It will be monophyletic. |
