28 How is the fern life cycle different from the moss life cycle? A fern gametophyte always has both archegonia and antheridia.The young gametophyte is haploid.The mature sporophyte is diploid.The mature sporophyte grows from the gametophyte.
29 Which of the following includes a plant embryo, a food supply, and a protective covering? pollen grainsporeseedgametophyte
30 Seed-bearing plants differ from all other plants in that they have vascular tissue.they do not have a gametophyte generation.their gametes do not require water for fertilization to occur.all of the above
31 The gametophytes of gymnosperms are found inside reproductive structures called flowers.cones.embryos.angiosperms.
32 When land environments became drier millions of years ago, many moss and fern species became extinct.mosses evolved vascular tissue.mosses and ferns no longer required water for reproduction.many angiosperm species became extinct.
33 The most ancient surviving seed plants are the mosses.liverworts.ferns.gymnosperms.
34 Which of the following statements is NOT true? Seed plants can coexist with seedless plants.The evolution of seed plants caused many species of mosses and ferns to become extinct.Early seed plants were successful because they were adapted to dry environments.Fossils of seed-bearing plants exist from almost 360 million years ago.
35 The four groups of gymnosperms are conifers, cycads, ginkgoes, and bryophytes.horsetails.liverworts.gnetophytes.
36 Which gymnosperms produce exposed seeds? conifers onlyconifers and cycads onlyconifers and ginkgoes onlyconifers, cycads, gnetophytes, and ginkgoes
37 There is evidence that Ginkgo biloba was the first gymnosperm to have evolved.evolved before most other living species of seed plants.evolved from an angiosperm.has characteristics that differ greatly from its ancestors.
38 Angiosperms produce seeds inside protective structures called pollen grains.cones.ovaries.petals.
39 Which term below is least closely related to the others? fruitseedovarycone
40 The specialized reproductive structure that evolved most recently is the seed.pollen grain.ovary.gametophyte.
41 An example of a monocot is a tomato.lily.rose.daisy.
42 The number of seed leaves distinguishes club mosses from mosses.angiosperms from gymnosperms.two classes of angiosperms.seed plants from seedless plants.
43 Unlike a dicot, a monocot has four or five petals per flower.two cotyledons.taproots.parallel leaf veins.
