Review of Plant Life Cycles 1 In the life cycles of all plants, there is an alternation of generations. This means that A B C D E 2 In plants, male gametes are produced by the A B C D E 3 A B C D E In moss, _____ produce sperm. A B C D E 5 pistil. ovary. sporophyte. antheridium. archegonium. Which of these represents the sporophyte generation of the moss life cycle? A B C D E 4 haploid sporophytes make haploid spores. meiosis in sporophytes produces haploid spores. gametophytes produce spores that develop into gametes. in plants, either the gametophyte or the sporophyte is unicellular. sporophytes and gametophytes are typically similar in appearance. embryos sporangia antheridia archegonia protonemata The sperm produced by mosses and ferns require _____ to reach an archegonium. A B C D E wind light animals moisture the development of a flower 4/13/2011 10:50:05 AM Page 1 Review of Plant Life Cycles 6 _________ are examples of seedless vascular plants. A B C D E 7 The conspicuous stage in the life cycle of a fern plant is a A B C D E 8 diploid sorus. diploid sporophyte. haploid sporophyte. diploid gametophyte. haploid gametophyte. In mosses gametes are produced by _____; in ferns gametes are produced by _____. A B C D E 9 Ferns Lilacs Mosses Pine trees Charophyceans mitosis ... mitosis mitosis ... meiosis meiosis ... mitosis meiosis ... meiosis binary fission ... mitosis Which of these structures in the life cycle of a fern is diploid? A B C D E A B C D E 4/13/2011 10:50:05 AM Page 2 Review of Plant Life Cycles 10 According to this phylogenetic tree, angiosperms are most closely related to A B C D E 11 Which of the following is NOT associated with flowers? A B C D E 12 style hypha carpel anther stigma The function of the endosperm in angiosperms is to provide A B C D E 13 green algae. bryophytes. gymnosperms. pteridophytes. charophyceans. nourishment for the pollen. a reward for animal pollinators. material for fruit development. material for flower development. nourishment for the developing embryo. Angiosperms differ from all other plants because A B C D E they produce fruits. they produce a pollen tube. they produce wind-dispersed pollen. the sporophyte generation is dominant. they use animals to disperse their seeds. 4/13/2011 10:50:05 AM Page 3 Review of Plant Life Cycles 14 Which of these is a male gametophyte? A B C D E 15 In pines, the female gametophyte contains _____, each of which contains a(n) _____. A B C D E 16 seed. immature sporophyte. immature male gametophyte. immature female gametophyte. food reserve for the immature sporophyte. In pine trees, pollen grains get to the ovule via the A B C D E 18 antheridia ... egg archegonia ... egg antheridia ... sperm cell archegonia ... sperm cell microsporangia ... egg cell In pines, an embryo is a(n) A B C D E 17 A B C D E eggs. micropyle. megaspore. pollen cone. integuments. Which of these statements is true about the gametophyte tissue that surrounds the pine embryo? A B C D E It is the remnant of the pollen tube. It functions as a diploid food reserve. It functions as a haploid food reserve. It functions as a triploid food reserve. It develops from the fusion of a microspore and a megaspore. 4/13/2011 10:50:05 AM Page 4 Review of Plant Life Cycles 19 Ovules are found within structure A B C D E 20 Which of these is unique to flowering plants? A B C D E 21 endosperm. megaspores. pollen grains. embryo sacs. male sporophytes. In flowering plants the integument of the ovule develops into a(n) A B C D E 23 pollen production double fertilization haploid gametophytes a dominant sporophyte generation an embryo surrounded by nutritive tissue The male gametophytes of flowering plants are also referred to as A B C D E 22 A B C D E fruit. cotyledon. seed coat. endosperm. sporophyte. A carpel (or pistil) is composed of A B C D E stigma, style, and ovary. ovary, ovule, and anther. petal, sepal, and stamen. zygote, anther, and endosperm. ovule, megasporocyte, and anther. 4/13/2011 10:50:05 AM Page 5 Review of Plant Life Cycles 24 A stamen consists of A B C D E 25 ovary and sepal. stigma and style. stigma and anther. stigma and filament. anther and filament. "Pollination" is the transfer of pollen grain to the _____ of a flower on the same plant or another plant of the same species.
