A) green algae B) red algae C) charophytes D) brown algae E) angiosperms Answer: C Topic: Concept 29.1 Skill: Knowledge/Comprehension 2) The structural integrity of bacteria is to peptidoglycan as the structural integrity of plant spores is to A) lignin. B) cellulose. C) secondary compounds. D) sporopollenin. Answer: D Topic: Concept 29.1 Skill: Knowledge/Comprehension 3) Which kind of plant tissue should lack phragmoplasts? A) bryophyte tissues B) diploid tissues of charophytes C) spore- producing tissues of all land plants D) tissues performing nuclear division without intervening cytokineses E) the meristematic tissues of fern gametophytes Answer: D Topic: Concept 29.1 Skill: Knowledge/Comprehension 4) The following are common to both charophytes and land plants except A) sporopollenin. B) lignin. C) chlorophyll a. D) cellulose. E) chlorophyll b. Answer: B Topic: Concept 29.1 Skill: Knowledge/Comprehension 5) A number of characteristics are very similar between charophytes and members of the kingdom Plantae. Of the following, which characteristic does not provide evidence for a close evolutionary relationship between these two groups? A) alternation of generations B) chloroplast structure C) cell plate formation during cytokinesis D) sperm cell structure E) ribosomal RNA nucleotide sequences Answer: A Topic: Concept 29.1 Skill: Knowledge/Comprehension Page 1 6) A researcher wants to develop a test that will distinguish charophytes and land plants from green algae. Which of the following chemicals would be the best subject for such an assay? A) chlorophyll a photosynthetic pigment B) carotenoids a class of accessory photosynthetic pigments C) starch a food storage material D) glycolate oxidase an peroxisomal enzyme that is associated with photorespiration E) flavonoids a class of phenolic compounds that is often associated with chemical signaling Answer: D Topic: Concept 29.1 Skill: Application/Analysis 7) In animal cells and in the meristem cells of land plants, the nuclear envelope disintegrates during mitosis. This disintegration does not occur in the cells of most protists and fungi. According to our current knowledge of plant evolution, which group of organisms should feature mitosis most similar to that of land plants? A) unicellular green algae B) cyanobacteria C) charophytes D) red algae E) multicellular green algae Answer: C Topic: Concept 29.1 Skill: Knowledge/Comprehension 8) On a field trip, a student in a marine biology class collects an organism that has differentiated organs, cell walls of cellulose, and chloroplasts with chlorophyll a . Based on this description, the organism could be a brown alga, a red alga, a green alga, a charophyte recently washed into the ocean from a freshwater or brackish water source, or a land plant washed into the ocean. The presence of which of the following features wouldsource, or a land plant washed into the ocean....
