Biology 1030 Spring 2008 Exam 1 Version 2 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. Which of the following Eukarya “supergroups” is most closely related to the supergroup Amoebozoa? A) Opisthokonta D) Alveotata B) Rhizaria E) Archaeplastida C) Discicristata ____ 2. 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) Radiolaria (radiolarians) D) Ciliophora (ciliates) B) Apicomplexa (sporozoans) E) Bacillariophyta (diatoms) C) Foraminifera (forams) ____ 3. Prokaryotic organisms are classified only in: A) Domain Archaea D) Kingdom Eubacteria B) Domain Bacteria E) Domains Bacteria and Archaea C) Domain Eukarya ____ 4. The ___________ is the sexual structure that produces egg cells in plants. A) archegonium D) stoma B) sporangium E) strobilus C) antheridium ____ 5. Members of this phylum of seedless vascular plants have a gametophyte called a prothallus, from which a sporophyte will grow and take over. The leaves of this dominant sporophyte form are called fronds, and sori are usually produced on the undersides of these fronds. A) Psilophyta (whisk ferns) D) Hepatophyta (liverworts) B) Pterophyta (ferns) E) Arthrophyta (horsetails) C) Cycadophyta (cycads) ____ 6. All living members of this seedless vascular plant phylum are classified in the same genus, Equisetum. Mem- bers of this phylum are characterized by having jointed, photosynthetic stems with scale-like leaves at the stem nodes; they also have silica deposits in some of their epidermal cells. A) Gnetophyta (gnetophytes) D) Anthocerophyta (hornworts) B) Lycophyta (club mosses) E) Arthrophyta (horsetails) C) Psilophyta (whisk ferns) ____ 7. Non-vascular plants with a dominant gametophyte that grows prostrate, with a sporophyte dependent on the gametophyte, and that are capable of asexual reproduction using gemmae are classified as: A) Anthocerophyta (hornworts) D) Psilophyta (whisk ferns) B) Bryophyta (true mosses) E) Hepatophyta (liverworts) C) Lycophyta (club mosses) ____ 8. 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)
