Biology 1030 Spring 2008 Exam 1 Version 3 Multiple Choice - 42 questions total, 2 points each (80 pt basis, 4 bonus points possible) Identify the letter of the choice that best completes the statement or answers the question. ____ 1. Plant spores give rise directly to A) gametes. D) gametophytes. B) sporophytes. E) seeds. C) sporophylls. ____ 2. 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 , and they make the unique carbohydrate laminarin for energy storage. A) Chlorophyta (green algae) D) Chrysophyta (golden algae) B) Rhodophyta (red algae) E) Dinoflagellata (dinoflagellates) C) Phaeophyta (brown algae) ____ 3. The gametophyte is the dominant stage in the life cycle for members of which of the following plant phyla? A) Arthrophyta (horsetails) D) Bryophyta (mosses) B) Psilophyta (whisk ferns) E) Pterophyta (ferns) C) Lycophyta (club mosses) ____ 4. The sac fungi have structures for sexual reproduction called: A) basidia. D) conidia. B) zygospores. E) mycorrhizae. C) asci. ____ 5. A plant that makes two types of meiospores, both megaspores and microspores, is called: A) dikaryotic D) heterosporous B) homosporous E) monoecious C) dioecious ____ 6. Members of this phylum are found in fresh water and on rotting vegetation and have an unusual life cycle. Spending most of their life as free-living, individual cells, a lack of food triggers them to aggregate into a multicellular "slug" that migrates toward light and then becomes a sessile sorocarp where sexual reproduction occurs. A species from this group, Dictyostelium discoideum , is often used in studies of multicellular co- ordination and development. A) Myxomycota (plasmodial slime molds) D) Acrasiomycota (cellular slime molds) B) Ciliophora (ciliates) E) Oomycota (oomycetes) C) Apicomplexa (sporozoans) ____ 7. This monophyletic group was defined only recently. The group is important for being in mycorrhizal rela- tionships with plants, with members of this group making endomycorrhizae. A) Chytridiomycota (chytrids) D) Glomeromycotoa (glomeromycetes) B) Ascomycota (sac fungi) E) Basidiomycota (club fungi) C) Zygomycota (zygomycetes) ____ 8. Which of these kingdoms is definitely NOT monophyletic? A) Protista D) Fungi B) Plantae E) Eubacteria C) Animalia ____ 9. This kingdom is composed only of complex multicellular eukaryotes with tissues and organs and with cell walls made of cellulose. A) Eubacteria D) Animalia B) Plantae E) Protista C) Archaebacteria ____ 10. Which of the following is a group that represents a clade? A) protists D) seed plants B) red and green algae E) seedless vascular plants C) nonvascular plants

____ 11. Members of this phylum have primarily calcareous tests. Deposit of their tests are common components of limestone rocks, forming chalks such as the white cliffs of Dover. They are an important fossil group, with a rich geological record going back over 200 million years. A)
