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 Which of these represents the sporophyte generation of the moss life cycle? A B C D E 3 wind light animals moisture the development of a flower _________ are examples of seedless vascular plants. A B C D E 5 A B C D E The sperm produced by mosses and ferns require _____ to reach the eggs. A B C D E 4 haploid sporophytes make haploid spores. meiosis in diploid 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. Ferns Lilacs Mosses Pine trees Charophyceans The conspicuous stage in the life cycle of a fern plant is a A B C D E diploid sorus. diploid sporophyte. haploid sporophyte. diploid gametophyte. haploid gametophyte. 4/13/2012 8:40:07 AM Page 1 Review of Plant Life Cycles 6 In mosses gametes are produced by _____; in ferns gametes are produced by _____. A B C D E 7 Which of these structures in the life cycle of a fern is diploid? A B C D E 8 A B C D E According to this phylogenetic tree, angiosperms are most closely related to A B C D E 9 mitosis ... mitosis mitosis ... meiosis meiosis ... mitosis meiosis ... meiosis binary fission ... mitosis green algae. bryophytes. gymnosperms. pteridophytes. charophyceans. Which of the following is NOT associated with flowers? A B C D E style hypha carpel anther stigma 4/13/2012 8:40:07 AM Page 2 Review of Plant Life Cycles 10 Angiosperms differ from all other plants because A B C D E 11 Which of these is a male gametophyte? A B C D E 12 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 an opening in the egg case called the A B C D E 14 A B C D E In pines, an embryo is a(n) A B C D E 13 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. 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. 4/13/2012 8:40:07 AM Page 3 Review of Plant Life Cycles 15 Ovules are found within structure A B C D E 16 Which of these is unique to flowering plants? A B C D E 17 endosperm. megaspores. pollen grains. embryo sacs. male sporophytes. A carpel (or pistil) is composed of A B C D E 19 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 18 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. A stamen consists of A B C D E ovary and sepal. stigma and style. stigma and anther. stigma and filament. anther and filament. 4/13/2012 8:40:07 AM Page 4 Review of Plant Life Cycles 20 "Pollination" is the transfer of pollen grain to the _____ of a flower on the same plant or another plant of the same species.
