Biology, 7e (Campbell) Chapter 30: Plant Diversity II: The Evolution of Seed Plants Chapter Questions 1) The sporophytes of mosses depend on the gametophytes for water and nutrition. In seed plants, the reverse is true. From which seed plant sporophyte structure(s) do the immature (unfertilized) gametophytes directly gain water and nutrition? A) sporophylls B) embryos C) sporangia D) sporopollenin E) ovary Answer: C Topic: Concept 30.1 Skill: Comprehension 2) Which of the following is not true concerning the sporophyte or gametophyte generations of flowering plants? A) The flower is composed of gametophyte tissue only. B) The sporophyte generation is dominant. C) The sporophyte generation is what we see when looking at a large plant. D) The gametophyte generation is not photosynthetic. E) The gametophyte generation consists of relatively few cells within the flower. Answer: A Topic: Concept 30.1 Skill: Comprehension 3) Which of the following is an ongoing trend in the evolution of land plants? A) decrease in the size of the leaf B) reduction of the gametophyte phase of the life cycle C) elimination of sperm cells or sperm nuclei D) increasing reliance on water to bring sperm and egg together E) replacement of roots by rhizoids Answer: B Topic: Concept 30.1 Skill: Comprehension 4) All of the following cellular structures are found in cells of angiosperm and gymnosperm gametophytes except A) haploid nuclei. B) mitochondria. C) cell walls. D) chloroplasts. E) peroxisomes. Answer: D Topic: Concept 30.1 Skill: Application 1

5) Plants with a dominant sporophyte are successful on land partly because A) having no stomata, they lose less water. B) they all disperse by means of seeds. C) diploid plants experience fewer mutations than do haploid plants. D) their gametophytes are protected by, and obtain nutrition from, the sporophytes. E) eggs and sperm need not be produced. Answer: D Topic: Concept 30.1 Skill: Knowledge 6) Seeds commonly provide for each of the following except A) a choice of germination location. B) dispersal. C) dormancy. D) a nutrient supply for the embryo. E) desiccation resistance. Answer: A Topic: Concept 30.1 Skill: Comprehension 7) In addition to seeds, which of the following characteristics are unique to the seed-producing plants? A) a haploid gametophyte retained within tissues of the diploid sporophyte B) lignin present in cell walls C) pollen D) A and C only E) A, B, and C Answer: D Topic: Concept 30.1 Skill: Knowledge 8) Which of the following most closely represents the male gametophyte of seed-bearing plants? A) ovule B) microspore mother cell C) pollen grain D) embryo sac E) fertilized egg Answer: C Topic: Concept 30.1 Skill: Knowledge 9) Suppose that the cells of seed plants, like the skin cells of humans, produce a pigment upon increased exposure to UV radiation. Rank the cells below, from greatest to least, in terms of the likelihood of producing this pigment. 1.
